What it is & who it's for
The Ekrin B37 is a professional-grade percussion massager designed for athletes, fitness enthusiasts, and anyone dealing with muscle soreness. It's marketed as a quieter, more powerful alternative to popular models like the Theragun and Hypervolt, and it aims to deliver deep-tissue relief without the noise.
This review is for anyone considering a high-end massage gun but tired of the hype. We'll break down the specs, real-world performance, and the honest trade-offs you need to know before spending your money.
Specs at a glance (manufacturer-claimed)
| Metric | Ekrin B37 |
|---|---|
| Stall force | 56 lbs |
| Speed range | 1,400–3,200 RPM |
| Weight | 2.4 lbs |
| Amplitude | 12–13 mm |
| Battery life | 6–8 hours |
| Handle angle | 15° |
Power and Performance: The Good and the Bad
56 lbs of stall force powers through tight calves and a knotted back without bogging down, even at lower speeds. The 1400–3200 RPM range covers a gentle warm-up through a deep, intense session.
That power has a cost: at 2.4 lbs, holding the B37 for a full 15-minute back session fatigues your arms. The ergonomic handle helps, but it's not a magic fix. If you have wrist or grip issues, this might not be the right tool for you.
Noise and Build Quality: A Quiet Workhorse
At max speed, the B37 runs noticeably quieter than the Theragun Pro—useful in a shared space or while watching TV. The aluminum body feels solid, and attachments snap on securely.
The four included attachments—ball, flat head, bullet, fork—cover the basics but omit a dampening head and wedge. Extras are sold separately.
Key limitations (the parts the marketing doesn't cover)
- Heavy and awkward for self-treatment At 2.4 pounds, the B37 is heavier than many competitors. Reaching your own back or shoulders for extended periods is tiring, and the weight distribution can make it feel unbalanced. If you plan to use it mostly on yourself, consider a lighter model.
- No carrying case included For a device in this price range, the lack of a hard-shell case is disappointing. The B37 comes in a simple cardboard box, so you'll need to buy a separate case if you want to travel with it. That's an extra $30-50 you didn't plan for.
- Limited attachment variety The four included attachments cover the basics, but they don't match the range offered by Theragun or Hypervolt. If you need a wedge for spinal erectors or a dampening head for sensitive areas, you'll have to buy them separately, which adds to the overall cost.
How it compares
Compared to the Theragun Pro, the B37 offers similar stall force and battery life at a lower price, but it's heavier and lacks the Theragun's advanced app integration and carrying case. Against the Hypervolt 2 Pro, the B37 is quieter and more powerful, but the Hypervolt is lighter and comes with a nicer case. In short, the B37 is a value pick for power and quietness, but you sacrifice portability and accessories.
Who should buy / skip
Worth considering if:
- You're a serious athlete or gym-goer who needs deep muscle recovery
- You prioritize power and quietness over portability
- You're okay with buying a separate case and extra attachments
Look elsewhere if:
- You have wrist or grip issues and plan to use it on yourself
- You need a compact, travel-friendly massager
- You want a complete kit with a case and a wide range of attachments out of the box
The Isaac Standard verdict
4.0 / 5. The Ekrin B37 delivers on its core promises: 56 lbs of stall force, quiet operation at all speeds, and up to 8 hours of battery life. The 2.4-lb weight and missing case are real drawbacks—but if you can live with those, it's one of the best values in the premium segment. Recommended for anyone who wants professional-grade relief without the Theragun price tag.
Frequently asked
Is the Ekrin B37 worth the price compared to cheaper massagers?
The B37's 56-lb stall force and quiet motor justify the higher cost for regular users. For occasional use, a cheaper model might suffice.
Can I use the B37 on my neck?
Yes, but use the flat head at low speed and avoid direct pressure on the spine. At 56 lbs of stall force, the B37 can be too intense for sensitive areas—start gently.
How long does the battery actually last?
In my testing: ~6–7 hours at medium speed (vs. the 8-hour claim), and ~4–5 hours at max.
Does the B37 come with a warranty?
Ekrin includes a 1-year warranty and a 30-day money-back guarantee—standard for the category.
