Quick Answer: Buy the Ekrin B37 if you want the most performance per dollar — at $229.99 it delivers 56 lbs of stall force (per Ekrin), up to 8 hours of battery, and a lifetime warranty. Buy the Hypervolt 2 Pro (~$329–$419) if you want the quietest gun, a slightly deeper 14mm stroke, and app-connected features. For most people the Ekrin B37 is the smarter value; for the quietest, most polished experience the Hypervolt wins.
Hyperice’s Hypervolt and Ekrin Athletics sit at two ends of the massage-gun market: one is a household premium name sold in gyms and Apple Stores, the other a direct-to-consumer challenger that undercuts the big brands on price while matching them on specs. If you’re deciding between the Hypervolt 2 Pro and the Ekrin B37, you’re really asking whether the premium gun is worth roughly double the money. We’ve tested both — here’s how they actually compare.
By the numbers: the Hypervolt 2 Pro runs a 14mm amplitude at up to 3,200 percussions per minute with a QuietGlide motor Hyperice tunes specifically for low noise, and it lists at $329–$419 (per Hyperice). The Ekrin B37 counters with a 12mm amplitude, 56 lbs of stall force — only about 4 lbs shy of the $599 Theragun Pro, per Ekrin — five speeds from 1,400 to 3,200 RPM, up to 8 hours of battery life on the v2, and a lifetime warranty, all for $229.99. The Hypervolt reaches marginally deeper and runs quieter; the Ekrin costs far less, resists stalling under harder pressure, and runs longer between charges. Either way the underlying benefit is the same: a 2020 study in the Journal of Sports Science and Medicine (Konrad et al.) found a single five-minute percussive treatment increased range of motion without reducing muscle strength — a result both guns deliver, which is why the choice comes down to noise, feel, and price.

Hypervolt vs Ekrin by the numbers
- Price: $229.99 vs $329–$419. The Ekrin B37 undercuts the Hypervolt 2 Pro by roughly $100–$190 (per each brand’s list price) — the single biggest factor for most buyers, and money that buys a lot of accessories or a second mini gun.
- Stall force: 56 lbs vs ~40–50 lbs. Ekrin publishes a 56-lb stall force for the B37, within about 4 lbs of the $599 Theragun Pro; the Hypervolt 2 Pro isn’t officially rated but reviewers measure it lower. Higher stall force means the head resists bogging down when you lean into dense muscle.
- Battery: up to 8 hours vs ~3 hours. The Ekrin B37 v2’s lithium-ion pack lasts up to 8 hours per charge (per Ekrin) versus roughly 3 hours for the Hypervolt 2 Pro (per Hyperice) — a real convenience if you hate charging or share the gun in a household.
- Amplitude: 14mm vs 12mm. The Hypervolt’s stroke reaches 2mm deeper (per each brand’s published specs), a modest edge for dense, stubborn muscle that the Ekrin partly offsets with its higher stall force.
- Evidence base: A 2020 study in the Journal of Sports Science & Medicine (Konrad et al.) found a single five-minute percussive treatment increased range of motion without reducing strength — a benefit either gun delivers, so the decision is about feel, noise, and price rather than results.
Hypervolt 2 Pro — for quiet, premium polish
Hyperice Hypervolt 2 Pro
- QuietGlide motor — one of the quietest guns on the market.
- 14mm amplitude reaches slightly deeper than the Ekrin.
- Bluetooth app with guided routines and pressure sensor.
- Trusted household brand with wide retail support.
The Hypervolt 2 Pro wins on refinement. It’s the quieter of the two — quiet enough to use during a phone call or beside a sleeping partner — and the app connectivity and pressure sensor add a layer of guidance beginners appreciate. If you want the most polished, quietest experience and don’t mind paying a premium for the Hyperice name, the Hypervolt is the more luxurious tool.
Ekrin B37 — for value and raw performance
Ekrin Athletics B37
- 56 lbs of stall force — within 4 lbs of the $599 Theragun Pro.
- Up to 8 hours of battery life on the v2 (USB-PD charging).
- Angled ergonomic handle that's easy on the wrist.
- Lifetime warranty — the best coverage in its class.
The Ekrin B37 wins on value. It matches or beats the Hypervolt on stall force and battery while costing $100–$190 less, and the lifetime warranty removes the long-term risk that comes with any motor-and-battery device. It’s marginally louder and skips the app, but for buyers who care about how hard and how long a gun works rather than brand cachet, the B37 delivers more massage gun per dollar.
Which should you buy?
- Buy the Hypervolt 2 Pro if: you want the quietest possible gun, value app-guided routines and a pressure sensor, prefer a mainstream brand with wide retail support, and don’t mind paying a premium.
- Buy the Ekrin B37 if: you want the most performance per dollar, prioritize stall force and long battery life, want a lifetime warranty, or simply don’t want to spend $400 on a massage gun.
- Want to go even deeper? If you’re chasing maximum amplitude, both lose to the 16mm Theragun Pro — see how it stacks up in our Theragun vs Hypervolt comparison.
The bottom line
There’s no wrong answer here, but the value gap is hard to ignore. The Ekrin B37 matches the Hypervolt 2 Pro on the specs that matter most — stall force and battery — for $100–$190 less and adds a lifetime warranty, making it the better value for most people. Pay up for the Hypervolt if quiet operation and app features are worth the premium to you; otherwise the Ekrin is the smarter buy.
