Ekrin B37 Review: Ekrin’s Secret Weapon Against The Big Names

Disclaimer: Our content is unbiased, non-sponsored and fact-checked. If you buy via links on our site, we may earn a commission. As an Amazon Associate, we earn from qualifying purchases.

So here’s the Ekrin B37 review. We’ve been itching to get this one done for a while.

We got it 6 months ago and have had a perfect time with it. Easing tension in our muscles after a hefty workout, or getting a much needed pre-workout muscle activation, or sometimes just using it to get our blood flow stimulated. We have a few things to say about it, so follow along. 

We got the Ekrin B37 because of the hype it received when it came out. You’re not alone in going for what is hyped. We all love what others love. It’s not a sin. But the gospel about this massage gun is not all hype. It’s not only the massage gun that put Ekrin Athletics out there, but it packs a lot of features that impressed us.

And since we love massage gun talk, this one carries power, aesthetics, (we loved it at first site) and offers real value for money. In fact, we’ve listed it as the best value massage gun for 2022.

Meet Ekrin Athletics

If you’ve been reading our massage gun reviews you’ve probably noticed how we’ve had to explain in some cases that we really don’t know about the company but we liked the massage gun anyway.

Well here’s one of those reviews where we can comfortably say that we know about Ekrin Athletics. Unlike many other brands, they’re not one of those private labels that only exist at Amazon.

In fact, they are one of the few USA massage gun brands! Take it from us, most brands out there are Chinease brands. They just pretend to be American.

Ekrin Athletics Massage Gun Brand

Ekrin Athletics is a relatively new company. They started off in 2019 with two former student athletes who wanted to share with others about being fit and healthy. They saw it fit to emphasize on muscle recovery and prevention of injury to athletes. 

A quick glance through their website and we found out that Ekrin is not a name they chose to stand out. We have seen percussion massagers with names that look like Wi-Fi passwords (they don’t mean much).

Ekrin actually means something. It’s a combination of two Greek Words (it’s Greek so bear with us here) that mean “Explosive Movement”. So we got excited to check out what else they have to offer and we found out that for now they only do massage guns. Which is perfect for us!

The Ekrin B37 percussion massager was their maiden product and boy, was it “explosive”. We know this because we’ve been reading a lot about how customers have loved this percussion massager and we’ve also had fun using it. They followed it with the newer B37s, later on made the mini-sized Bantam after which they released their third full-size massager, the 365 model.

Any keen customer looking to buy a massage gun will definitely have a few questions about the company. For example; do they offer warranties, or what’s their return policy like, do they respond quickly to customer questions? Well, we have interacted with Ekrin Athletics and we can give them a good nod on all these questions.

We had a few things to ask about their massage gun. No, we didn’t have any problems with it, we just wanted to get clarification on a few things. Like how’s their return policy like, and also find out the conditions for their LIFETIME WARRANTY.

Sometimes you just want to get answers directly from company representatives about their product, and we are glad that the response was quick and efficient.

So let’s get into the Ekrin B37 massage gun review, shall we?

Ekrin B37 Specifications (according to Ekrin)

First Impressions

So first things first. You can tell that Ekrin Athletics really mean business with the quality of the B37’s carrying case. It’s nicely built and straightaway tells you that whatever’s inside is not a toy.

b37 package box
The B37 comes in a high-quality hard case.

We’ll go ahead and call it a nice little travelling case. It has two zippers which again felt really like we were opening a premium package. Enough about the case though.

Inside, the contents are pretty well organized. We noticed the massage heads were arranged nicely. There’s the device; kind of sticks out in the middle of the case, and then the charger.

The device itself is impressive, first to look at, and then also to touch. The satin paint gives the Ekrin B37 a stylish and glossy look.

Holding it gives you the impression that it’s well thought out. It feels sturdy and durable. Not one of those massage guns that you first hold and straightaway can tell that it won’t go the distance.

We noticed it has just the one button that you use to turn it on and off and also when you need to change the speeds. You guessed it, it’s simple.

Yet we might say for us simple is better. It’s much easier to know you won’t have to fiddle with it mid-massage trying to figure out what button does what exactly.

Operation mode is to long press if you want to turn it on or off and then quick presses will allow you to change speeds. 

Also, since it’s simple use, you don’t get the LCD option with this device. Someone might argue that a modern device should at least have this kind of sophistication, and for good reason too. But we like the simplistic approach.

Plus, it doesn’t take anything away from the performance, which is what matters most.

The Attachments

So the massage heads are pretty standard we’d say. But they’re really nicely built with a premium touch that we liked. The B37 has four; bullet head, ball head, spine/fork head, and the flat head.

A bit on what we thought about the attachments on this one:

Round / Ball Head

We use the ball head to get more of a general massage. If you have used a massage gun before you know this is the go-to attachment. It’s always the lazy massage gun head because 90% of the time it’s the one always attached.

And the Ekrin B37 one is a bit special, we might say. It’s made with a higher quality EVA foam that we liked. Not like one of the cheap forms we have seen from the low-end massage guns. It felt really smooth on our glutes and hamstring.

b37 attachment round ball

Fork / Spine Head

You guessed it; the fork or spine head is used around the spine. The two prongs go either side of the spine and activate the muscles around there. It also works on the lower back pains.

The Ekrin B37 one was perfect again for us. It’s made of tough plastic. We actually enjoyed using it around the calves as well. Some of the bigger guys have had fun with it.

Flat Head

The flat head is what we call the must-have. It’s multi-purpose. And our favorite. It works on diverse sets of muscles. But we actually love using it for our larger muscles, that’s the pecs, the glutes and calves.

The B37 one is made with hard plastic. It still looks rather new considering how long we’ve used it.

b37 attachment flat

Bullet Head

Thebullet head is the focus head. We use it especially when we have pain in certain muscles. We have heavy lifters in our team and occasional shoulder sprains are not uncommon.

For this, Ekrin chose hard plastic as well and we’ve had good fun with it.

b37 attachment bullet

You’ve probably noticed that the massage heads, apart from the ball head, are all made of hard plastic. This, you might say, doesn’t make for a smooth massage like what perhaps Achedaway would offer. But for a novice company making their first product to this standard, we might argue is a plus. We’ll get into the praises in just a bit, hang on. 

The heads can be easily attached and removed. Actually, apart from the fork head which has a little line on it that indicates where it needs to go in, the other heads just require you to do tiny bits of push and pull.

The line on the fork head is to prevent it from spinning around as you massage the spine area. We did notice though smaller guys appearing to use a bit of force trying to pull the heads off, but the bigger guys had no such problem.

ekrin b37 all 4 attachment

Other things we found in the bag include the instructions manual. They’ve got special information on there on how to use the heads and also just general massage gun use stuff (if you’ve never used a massage gun before don’t worry).

Our case also included a nice EKRIN sticker which we felt is a nice touch from the company. Shows they do care, and we love small details.

Size, Weight, Ergonomics

The gun itself is pretty light. At 2.2lbs, feels pretty standard.

There are lighter guns out there we have to agree, but this one feels just about the right weight. We have used heavier guns that are low standard. We think most of the weight is accounted for by the motor and perhaps the high-quality in-built Samsung battery.

It’s just about the perfect size we might say. For a full-scale massage gun it doesn’t feel as bulky as some of the industry massage guns we’ve used before. We’ve tested some power-drill shape guns that are way heavier (Hypervolt 2 Pro and Theragun Pro feel a bit dense in comparison). 

We were really impressed by the handle on this gun. Instead of staying with the industry standard of T-shaped massage guns, Ekrin went with a unique 15-degree angled handle.

This we might say is the standout genius of this device (at least by just looking at it). Many of the straight or T-shaped massage guns we have used tend to put so much tension on our wrists that we can barely even get a 3-minute session without having to stop.

ekrin b37 15-degree angled handle
15° angled handle.

The 15-degree angled handle makes for great ergonomics on the B37. It allows you to reach almost 90% of the body muscles without having to work your arm into difficult positions.

We also found out that with this design we could use the massage gun for longer than we have done with other massage guns (we have tested many).

Ekrin doesn’t say it, but even if you were giving a massage to a colleague, the design gives a comfortable two-handed grip (the little extension at the top). You could argue that maybe Theraguns have better handles, but Ekrin did well here for a value massage gun.

The downer here though (not catastrophic) is that the handle’s diameter felt a little large for some of the guys with smaller hands.

But Ekrin more than makes up for it with a nicely done silicone rubber grip. If you are a little short on the length of your fingers then don’t worry, the rubber grip ensures the device doesn’t slip from your hand when you are using it.

For those with smaller hands, Ekrin released the entry-level 365 model. It is lighter and slimmer, but not as powerful as the B37. Check out our hands-on Ekrin 365 review for more details.


To be honest we were a little worried about how this device would perform given we had already tested some of the industry giants (Theragun and Hypervolt). We decided to test it based on what anyone would want in a massage.

Here’s some insight into what the Ekrin B37 can give you…

Stroke Length / Amplitude

We can often tell the amplitude of any massage gun by looking at the lengths of the attachment heads it comes with.

Amplitude just refers to how deep the gun can hit

This device offers what Ekrin says it does.

At 12mm it offers the right punch needed to penetrate the muscle deep enough to improve blood floor, get to the sore muscles, and also break up the lactic acid accumulation.

12mm is not nearly enough to rival Theragun’s 16mm or Opove Max’s 15mm but to be fair it offers just enough. Plus, the high stall force makes up for this.

Verdict It has the right amplitude to give deep muscle massage.

b37 12mm stroke length amplitude

Stall Force

After an intense workout, some of us like to get our big muscles worked on. Sometimes in order to get really deep into say, the pecs, we have to press the gun really hard on to the body. This can sometimes stop the massage gun.

That force needed to stall or stop the gun is what is known as the stall force. 

For a massage gun under $200, the B37 really shines with a 56lbs. stall force. This is impressive because its peers don’t even get close. We’ll not get over our heads here especially when it’s a couple of pounds behind Theragun Pro and Achedaway Pro, but considering its size we would be pretty fair in declaring it powerful enough.

We noticed that the stall force is progressive with speeds. To be fair, at the slowest speed it stalls with 28lbs, second speed with 32lbs., third with 40lbs., fourth with 52lbs., and then finally it’s hardest to stall at highest speed with 55lbs. We tried stalling it just as practice and we had to apply a fair amount of pressure to do it.

Verdict At higher speeds this device can provide deep-to-the-bone massage.

B37 Muscle Recovery Massage Gun

Performance Parameters Comparison

Let’s see how B37 compares against other popular competitors.

Stall Force (lbs.)

Our Take
Ekrin B37 offers a lot of stall force. 56 lbs. is more than the top range Hypervolt 2 Pro. It’s well enough to break through those knotted muscles and tissues.

Stroke Length (mm)

Our Take
12mm amplitude is not industry leading, but more than enough for deep tissue massage (especially when paired with 56lbs. of stall force)

Percussions and Speed Levels

The B37 revs between 1400 – 3200RPM. It is what they advertised, and we found it accurate — our laser tachometer gave us the same result.

Pretty standard range, you might say. Fair enough, but what impressed us is how low you can start. Even industry giant Theragun starts at 1750RPM.

You can get precise muscle penetration especially when you are using more pressure. It has simple LED indicators that light up as you change the speeds. It revs across 5 speeds.

But perhaps the most stunning feature of this gun is its ability to deliver the range regardless of the pressure exerted against the skin. See, most (like 90% or so) massage guns are not powerful enough to keep revving under pressure. Press them slightly, and they slow down, so you don’t even get close to advertised percussions — This Ekrin’s different. Thanks to the high stall force, it just keeps revving, regardless of the force applied and speed selected.


The battery is a Samsung lithium ion (Li-On) with 2550 mAh capacity. We were a little surprised how Ekrin managed to pack a powerful battery into a rather small device.

Kudos to Ekrin for actually specifying the kind of battery inside the B37. We’ve seen devices that don’t specify this that have gone on to deteriorate in quality in less than 3 months (looking at you, Toloco).

ekrin b37 wall charger
2550 mAh capacity give between 5-8 hours of use.

A single charge will give between 5-8 hours of use depending on how long you use it and the amount of pressure you use during your massage sessions.

If you have 10-minute daily sessions it should be able to go for 10 days or even more. There are 4 LEDs below the power button that indicate the charge level. 


We wouldn’t say it’s too noisy and we also wouldn’t say it’s the quietest gun we’ve seen, but it’s quiet enough. It’s one of those things you have to use and judge.

But on our part, we didn’t have to raise the TV volume when using it. Ekrin say it’s 35 – 55dB depending on speed but it goes from 50dB to just over 60dB, with a background noise at 35dB.

One thing we noticed is that it doesn’t rattle much when pressed to the body. Also, the vibrations don’t transfer to the handle. Which makes it quite comfortable to use.

Price, Warranty and Where to buy

The device goes for $229.99 but you can get it at $183.99 with 20% off if you use the coupon code MGA20. Buy it in Ekrin store here.

You can buy the device from the company’s website. Take advantage of their top notch customer service. They offer a lifetime warranty and lifetime customer support. Also, while there you can check out the reviews from satisfied customers.

Ekrin B37 in Action

The B37 is a perfect all-rounder. Long, angled handle will give you about an inch or two more when reaching the lower back. It is also easy to manoeuvre – weighs only 2.2lbs, and has a lot of rubber on a handle.

Who is it Best For…

The B37 is a versatile device that will serve a wide range of users.

We’ll go ahead and recommend it to pro athletes and bodybuilders. Yes, this percussive device can give deep-to-the-bone massages even for guys with bigger muscles. 

Also, if you’re looking for a good massage to use at home when you need a stronger massage, this device will serve you well.

If you haven’t used a massage gun and are looking for one, this is a good device to start with. If you don’t have $599 to spend on Theragun Pro but want a premium-made device, this gun is worth consideration.

Get it from Ekrin directly and save $46 by applying the MGA20 promo code at checkout.

We can recommend the B37 to therapists and chiropractors who want a versatile and powerful device. The disadvantage though, is that you won’t have the option of removable batteries like you would if you got the Theragun.

Ekrin B37 vs Theragun

When it comes to Ekrin B37 vs Theragun, we would pick Theragun Pro or Theragun Elite to compete, or in this case compare to the B37.

We checked out Theragun Prime but the specs on it are too weak to compare with this. The Theragun Mini is a whole different category. It’s a small portable device and comparing it to the B37 just wouldn’t be fair at all.

ekrin b37 vs theragun
Ekrin B37 vs Theragun PRO

The advantages of our Theragun picks over the B37:

  • Theragun punches harder with their 16mm amplitude compared to Ekrin B37’s 12mm.
  • Pro and Elite both have OLED screens (you can read speed changes on there). Ekrin B37 doesn’t have any screen.
  • Theragun Pro has replaceable batteries (although the new, 5th Generation Pro no longer comes with two batteries included. There is just one.)
  • Both Pro and Elite have built-in reactive force meter.
  • Both Elite and Pro have Bluetooth connectivity and work with a dedicated app. But we’ve heard rumors that Ekrin could be working on an app.

However, the Ekrin B37 stands out with these points:

  • Ekrin B37 has a powerful stall force of 56lbs. Only Theragun Pro has a higher force at 60lbs. Elite is way short at 40lbs. and just to mention that the B37 has a stall force twice that of Theragun Prime.
  • The Theraguns have percussions that range between 1750-2400rpm. The B37 has speeds ranging between 1400-3200. Apart from the short 12mm amplitude, we would argue that the B37 can provide a more intensive massage.
  • The B37’s battery will last up to 5 hours compared to the Theraguns’ which can only go for 2-2.5 hours before they run out of juice.
  • B37 is less noisy (lower by 7-9dB). Ekrin’s sound it smoother, too. Theragun’s a bit harsh.
  • Ekrin offers a lifetime warranty. Only the Theragun Pro offers a 2 year warranty, the other models have a 1-year warranty each.
  • Ekrin is cheaper. With the MGA20 code it goes for $183.99, a 20% off the regular price. Theragun Pro goes for $599 while Elite will cost you well over two times more.

Some similarities we noticed:

  • Both Theraguns have 5 defined speeds just like the Ekrin B37.
  • Theragun Prime and Elite also weigh 2.2lbs, but the Pro is noticeably heavier (2.8lbs.)

Theragun have made a name for themselves because they offer premium quality. However, you’ll also have to bear with their premium pricing.

Ekrin may be the “who’s he” of the industry, but with excellent customer service and specs that go toe to toe or even beat Theragun we’d opt for it over the giants. The 50-70% lower price here is the deal breaker.

Ekrin B37 vs Hypervolt

Ekrin B37 Vs Hypervolt 2 Pro
Ekrin B37 vs. Hypervolt Plus

Hypervolt is a well-known industry massage gun. We can use Hypervolt 2 Pro as Ekrin B37’s peer. Here’s our input for the Ekrin B37 vs Hypervolt comparison:

Similarities, not many of them:

  • Ekrin B37 and Hypervolt 2 Pro have 5 speed levels each.
  • They also have similar size.
  • Both have similar noise levels, which means they are both quiet massage guns.

Differences :

  • Hypervolt 2 Pro is a high-amplitude device (14mm). Ekrin belongs to the middle-amplitude category (12mm.)
  • B37 revs much faster than Hypervolt 2 Pro. It maxes out at 500rpm more (3200 vs 2700).
  • B37 also starts at lower frequencies. You get 1400 percussions per minute at the first speed, Hypervolt starts at 1700.
  • B37 betters all Hypervolts in the stall force category. It has nearly twice as much power than the regular Hypervolt (56 lbs. vs ~25 lbs.). It is also much more powerful than Hypervolt 2 Pro, which has about 35lbs. (Hyperice doesn’t disclose it, it is our estimation).
  • B37 has better ergonomics with the slightly tilted handle. The Hypervolts are power drills.
  • Ekrin has a stronger battery (5-8 hours compared to 2-3 hours). But Hypervolt 2 Pro will offer you the option of removables.
  • Hypervolts have 5 attachments, that’s one more than the B37 which has 4.
  • You get Bluetooth with Hypervolts. Not so with the B37.
  • You get the force meter (pressure sensor) with the Hypervolt Plus. No such in B37 (but the more advanced Ekrin B37s has one)
  • B37 has a nice carrying case. Hypervolts don’t even offer you one.
  • Warranty: Hypervolts have 1 year, Ekrin has lifetime.
  • Price: Hypervolt 2 Pro currently goes for $349 at RecoveryforAthletes.com, B37 is $183.99 with the code MGA20.

If you like the Bluetooth that comes with the Hypervolts or are just into their fancy badge then by all means go for the Hypervolts. However, we think that in terms of real performance specs, the B37 outperforms all Hypervolt devices by a large margin.

On top of that you get a lifetime warranty and also get to save almost half of the price. Yes, Ekrin B37 is our pick here.

B37 Percussion Massager Alternatives

Opove M3 Pro Massage Gun New Version 2022
Opove M3 Pro
(new 2022 version)

Opove M3 Pro 2

The new Opove M3 Pro 2 is the latest deep tissue percussion massage gun from a known Hypervolt competitor, Opove. It’s the company’s answer to Hypervolt 2 Pro, Hyperice’s top-shelf gun.

The M3 Pro Max is a reasonably powerful massage gun is even cheaper than Ekrin, but has slightly less stall force available, and doesn’t percuss as fast.

If you want something that looks very Hypervolt-ish but don’t have the extra bucks to spend, then this is a worthy option.

As far as the specs are concerned, the M3 Pro Max punches up to about 40-45lbs. and max out at 2600 RPM. The amplitude is the same 12mm, so it’s within our sweet-spot range.

Compared to B37, it has about 10-15 pounds less stall force, and is quieter than the B37. Ekrin revs faster though, by 600 rpms (2600 vs 3200) so it has be a tad louder due to that.

Opove gun comes with 6 heads and a 2600 mAh battery that delivers similar juice with a single charge. Ekrin might have an edge here though, since it features a Samsung-branded battery.

Opove holds well due to good handle shape (slightly oval), but it is the B37 that will hold better, due to the angled handle it has, and less weight (2.2 vs. 2.5lbs)

The M3 Pro goes for $199 but you can use our link to get a sweetened deal and save up to $80. Get it here at $119.

One thing to keep in mind is that you’ll get a 1-year warranty if you buy the M3 Pro Max. Ekrin B37 will get you a lifetime one.

Lifepro Sonic Massager
Lifepro Sonic Pro

LifePro Sonic

This one’s similar to the Opove and Hypervolt, at least in terms of the power drill-like design.

This budget massager offers the amplitude of 10.5mm (advertised 12mm), so it is going to feel slightly more vibrational than our beloved B37.

The stall force also isn’t on par with Ekrin’s, but if you’re just starting with massage guns, chances are that Opove-like 40lbs (or likely a tad less), will be enough.

The Sonic has a decent speed range of between 1200-2800rpm. Interestingly, it starts lower than Ekrin, but does’t rev as fast. It’s calibrated with 5 speeds, same as the two other guns we’ve talked about. We think 5 speed levels is more than enough for the range.

In the same spirit of a little too much, the gun comes with 8 attachments. Actually we might give them this one. 8 attachments sound cool especially if you are a therapist, even though some of them feel somewhat similar.

Its battery is powerful, offering 2600mAh worth of juice. Same as Opove and pretty similar to B37 that has a 2550mAh battery.

It has LED indicators that show battery level and speed (in frequencies). It’s louder than B37, with up to 70dB but this is still a reasonable result for such a device that cheap.

Lifepro is a trusted brand. They also offer a lifetime warranty, just like Ekrin.

It only costs $116.99 with our MGA10 code that gives you 10% OFF the regular price ($129.99). You can get it right here.

Ekrin B37 Review – Final Thoughts

We’ve come to the end of our Ekrin B37 review and we have to say it didn’t disappoint.

It gave us what we wanted: high quality, well thought out, premium components (like the powerful in-built Samsung battery), and a good motor that packs just the right punch.

It’s perfectly balanced and we were impressed with the 15-degree angled handle. The lifetime warranty is a huge plus.

It’s very much a recommended buy. We think it’s reasonable to get this device than go for the industry darlings like Theragun and Hypervolt.

And don’t forget you can now get it at $183.99, which is 20% off the regular price.

Ekrin B37 Rating
  • Quality
  • Effectiveness
  • Usability
  • Accessories
  • Price Value


Ekrin’s B37 percussion massager is a powerful, yet slick-looking device that outperforms some of the biggest names in the business. It holds confidently, comes with the right set of accessories, features a lifetime warranty and, perhaps most importantly, it is able to provide the deep-to-the-bone massage.

  1. I love my Ekrin B37S, today a buddy at the gym asked me to research the best value / price for it, I bought mines in 2020 and for whatever reason I keep reading it has “4 attachments” but mines came with 6 attachments? No complaints all around great value for price!

    • Thanks for the comment! B37s comes six attachments; it is the B37 that comes with four.

      Both of them are fantastic value massage guns, depending on what power/features you are looking for.

      Hope it helps!
