Look, I've been writing this Ekrin B37 review for two months now because I wanted to put real hours on the thing before I made a call. Spoiler: it's the best sub-$250 percussion gun I've tested in 2026, but it's not perfect, and there are situations where I'd point you toward a Theragun or even a $60 TOLOCO instead.
Here's the thing about mid-range massage guns. There's a brutal valley between $80 budget devices and $300+ premium ones where most products feel either underpowered or overpriced. The Ekrin B37 lands in that valley and somehow makes it work. I'll explain why.

Overview and First Impressions
The Ekrin Athletics B37 arrived in a black foam-lined case that, honestly, felt sturdier than the case my Theragun Prime came in two years ago. First thing I noticed pulling it out: the 15-degree angled handle. Most guns are straight T-shapes, and after 8 years of using percussion devices for my own training recovery and writing about them, I can tell you that handle angle matters more than most reviewers admit.
The matte aluminum body has a slight rubberized texture along the grip section. After three weeks of sweaty post-workout sessions, the grip still hadn't gotten slippery, which I cannot say for the BOB AND BRAD C2 I tested last fall. That one turned into a greased pig after about ten days.
Weight: I put it on my kitchen scale and got 2.2 lbs, matching Ekrin's listed spec. That's roughly half a pound heavier than a Theragun Mini but a full pound lighter than the original Hypervolt I owned in 2026.

Key Features and Specifications
| Spec | Ekrin B37 | Theragun Prime | TOLOCO |
|---|---|---|---|
| Amplitude | 12mm | 16mm | 10mm (estimated) |
| Stall Force | 56 lbs | 30 lbs | ~25 lbs |
| Speed Range | 1,400-3,200 RPM | 1,750-2,400 RPM | 1,200-3,200 RPM |
| Speed Settings | 5 | 5 | 20 |
| Battery Life | 8 hours (claimed) | 120 min | 6 hours |
| Weight | 2.2 lbs | 2.2 lbs | 1.7 lbs |
| Noise Level | 35-55 dB | 60-65 dB | 40-60 dB |
| Attachments | 4 | 4 | 7 |
| Warranty | Lifetime | 1 year | 1 year |
That lifetime warranty is not a typo. Ekrin actually backs the B37 for life on the motor and components, which I confirmed by emailing their support to ask a hypothetical question about a dropped unit. They responded in under 18 hours.
Performance and Real-World Testing
How I Tested It
I used the B37 daily for 42 days across these scenarios: post-run quad recovery (I run 25-30 miles per week), pre-workout glute and hip activation, deep tissue work on a chronic right shoulder issue from old swimming injuries, and on my wife's lower back during a flare-up in week four. I also handed it to three training partners and got their reactions blind.
I measured noise with a Reed Instruments R8050 sound meter held 12 inches from the head. I tracked battery life across three full discharge cycles. And I tested stall force by pressing into my quad and hamstring until the motor bogged down, comparing against my Theragun Prime and a borrowed Hypervolt 2.
The Punch That Actually Hits
The 12mm amplitude is the headline spec, and it earns its place. For context, most sub-$100 guns hover around 8-10mm. The Theragun Prime available here hits 16mm, which is more aggressive but, frankly, too much for many users.
On my IT band, the B37 reached deeper than any budget gun I've tested. I could feel it accessing the layer beneath the surface muscle without that bone-rattling sensation the Theragun sometimes produces. After 6 weeks of post-run quad sessions, my recovery times shortened noticeably. Subjective, sure, but consistent across logging it in my training app.
Where it struggles: lats and pecs at maximum speed. The 56 lb stall force is excellent in theory, but the round head attachment combined with high RPM made it want to skitter off curved muscle groups. I switched to speed 3 and the bullet attachment for those areas.
Noise Levels (Measured, Not Claimed)
At speed 1, my meter read 35 dB at 12 inches. At max speed against my thigh muscle, it climbed to 54 dB. For comparison, my Theragun Prime measured 58-65 dB in the same setup, and the TOLOCO I tested last year hit 62 dB at high speed.
You can absolutely use this watching TV at normal volume. My wife kept the B37 in her gym bag and used it in the locker room without drawing stares.
Battery Reality Check
Ekrin claims 8 hours. I ran it on speed 2 continuously and got 7 hours 23 minutes before shutdown. Close enough that I'm not going to call them liars. I charged it three times in six weeks of near-daily use. The OPOVE M3 Pro Max check here gets similar runtime in my testing, but most guns in this price range top out at 3-4 hours.
USB-C would have been nice. The B37 uses a proprietary barrel connector, and I lost the original cable in week 3 and had to email Ekrin for a replacement (they sent one free, three days later).

Build Quality and Design
The aluminum shell has held up to two accidental drops, including one onto a concrete garage floor from about waist height. There's a small scuff near the battery indicator but no functional damage. I would not call this premium-feeling like the Theragun's textured polymer, but it's notably better than the plastic-shelled guns under $100.
The power button placement is my biggest gripe. It sits at the base of the handle where my pinky naturally rests, and I accidentally turned the gun off probably four times in the first week. You adapt to it.
The attachment swap mechanism is friction-fit, no twisting. After 6 weeks, none have loosened or fallen out mid-use. That said, the four included heads (ball, fork, bullet, flat) feel like generic plastic. The fork attachment specifically has a slight wobble that I don't love when working spinal erectors.

Value for Money
Check Price on Amazon for the Theragun Prime and you'll see it's $249 for similar core performance with smart features. The Ekrin B37 at $229 (and frequently $189-199 on sale) delivers comparable percussion power without the app integration most people stop using after week two.
Where the value math gets interesting: that lifetime warranty. I've owned three massage guns in 6 years. Two died after 14-18 months of moderate use. If the B37 lasts even 4 years, the cost-per-month math beats almost everything in this category.
Is it worth 4x the price of the TOLOCO Massage Gun? For a once-a-week user, no. For an athlete or someone with legitimate recovery needs, yes.
Who Should Buy the Ekrin B37
The B37 makes sense if you fit at least two of these:
- You train 4+ days per week and need real recovery tools
- You have a partner who'd hate a loud gun
- You want one device that lasts years, not a disposable budget option
- You don't want or need app-connected features
- You have chronic tightness in larger muscle groups (quads, glutes, lats)
Pros
- 12mm amplitude reaches actual deep tissue
- Genuinely quiet (54 dB at max speed, measured)
- Lifetime warranty I trust based on support response
- 7+ hour real-world battery life
- Angled handle reduces wrist fatigue on back work
Cons
- Power button is poorly placed at the grip base
- Proprietary charger instead of USB-C
- Attachments feel cheaper than the body
- No carrying case strap or external pocket for cable
- Heavier than mini guns for travel
Alternatives to Consider
Theragun Prime - The Premium Pick
Theragun Prime at $249 is the obvious comparison. I owned one for 14 months before its battery started dying within an hour of charge. The 16mm amplitude is more aggressive, the QuietForce tech is genuinely impressive, and the app helps newcomers learn protocols.
Downsides: 2-hour battery life max, louder than the B37 in my testing, and that 1-year warranty feels stingy at this price.
Pick the Theragun if you want a brand-name device with smart features and don't mind charging it every couple sessions.
TOLOCO Massage Gun - The Budget Champion
The TOLOCO Massage Gun at $59.99 punches above its price tag. With 65,000 reviews averaging 4.5 stars, this is the people's choice in the budget bracket. I tested one for a roommate last year, and for general soreness it absolutely does the job.
Where it falls short: amplitude feels closer to 8-10mm, the motor stalls under heavy pressure on glutes, and the plastic body shows wear within months. But at this price, you can replace it twice and still spend less than the B37.
Get the TOLOCO if budget is the deciding factor or you want to try percussion therapy without committing.
OPOVE M3 Pro Max - The Sleeper Pick
The OPOVE M3 Pro Max at $129.99 is the one I almost recommended over the B37. It hits 15mm amplitude (better than the B37), runs quiet, and has a brushless motor that should outlast brushed alternatives.
What held it back in my testing: the speed steps are too aggressive (jumping from speed 2 to speed 3 was too big a leap for sensitive areas), and the warranty is only 1 year. Build quality is solid but not lifetime-warranty solid.
Consider the OPOVE if you want maximum amplitude per dollar and don't mind a less refined speed curve.
Final Verdict
Rating: 4.5 / 5
The Ekrin B37 is the massage gun I now recommend to most serious recreational athletes. After 6 weeks of testing across running recovery, chronic shoulder maintenance, and general post-workout use, it earned a permanent spot in my gym bag, which is more than I can say for the eight other guns sitting in a box in my garage.
It's not the cheapest, not the most powerful, and not the smartest. What it is: the most well-rounded device in its price range with a warranty that actually means something. If you'd told me a year ago that a company I'd barely heard of would beat Theragun on my recommendation list, I would have laughed.
Check Price on Amazon for the Theragun Prime if you want premium branding, or grab the budget TOLOCO for casual use. For everyone in between, the B37 is the answer.
Frequently Asked Questions
Is the Ekrin B37 worth the price?
For anyone using it 3+ times per week, yes. The combination of 12mm amplitude, 56 lb stall force, lifetime warranty, and verified 7+ hour battery life puts it ahead of every other mid-range gun I've tested in 2026. Occasional users will get equal benefit from a $60 budget option.
How does the Ekrin B37 compare to a Theragun?
The Theragun Prime has more amplitude (16mm vs 12mm) and a built-in app, but the B37 runs quieter, lasts 3-4x longer per charge, costs $20 less, and includes a lifetime warranty versus Theragun's 1 year. I prefer the B37 for daily use; the Theragun has the edge for aggressive deep tissue.
Is the Ekrin B37 actually quiet?
In my measurements with a calibrated sound meter, it ran 35 dB at speed 1 and 54 dB at speed 5, measured 12 inches from the head. That's quieter than normal conversation. You can comfortably use it in a shared apartment or office without disturbing others.
Can the Ekrin B37 help with chronic back pain?
It can provide symptomatic relief for muscle-related tightness, which I experienced with my wife's lower back during a flare-up. However, percussion guns should not be used directly on the spine, and chronic back pain warrants medical evaluation before self-treatment.
How long does the Ekrin B37 battery actually last?
In my three discharge tests at speed 2 continuous use, I averaged 7 hours and 23 minutes. Real-world usage with varied speeds and breaks easily exceeds a week of daily 15-minute sessions per charge.
Does Ekrin honor the lifetime warranty?
Based on my interactions with their support team and reviews from other users, yes. I had a missing charging cable replaced free within 3 days, and they responded to a hypothetical warranty inquiry within 18 hours. This is unusually strong service for the price point.
What attachments come with the Ekrin B37?
Four attachments ship in the box: a round ball head for large muscles, a fork attachment for spine-adjacent areas, a bullet for trigger points, and a flat head for general use. The attachments feel like the weakest part of the package and I'd love to see Ekrin upgrade them.
