Quick Answer: Buy the Ekrin B37 if you want the most performance per dollar — at $229.99 it delivers 56 lb of published stall force, up to 8 hours of battery, and a lifetime warranty. Buy the Hypervolt 3 Pro ($349) if you want the harder-hitting gun (70 lb published stall force), the quietest operation (51dB), and a heated head included in the box. For most people the Ekrin B37 is the smarter value; for raw force and built-in heat the Hypervolt 3 Pro 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. Hyperice replaced the entire Hypervolt line in March 2026 — the Hypervolt 2 Pro this comparison used to feature is now a clearance-only holdover — so the real premium matchup today is the Ekrin B37 against the current Hypervolt 3 Pro. We’ve tested both — here’s how they actually compare.
By the numbers: the Hypervolt 3 Pro runs a claimed 51dB QuietGlide motor at up to 70 lb of published stall force — Hyperice’s March 2026 refresh was the first time the brand published stall force at all, but it still doesn’t publish an amplitude figure for any 2026 Hypervolt model — and it lists at $349 with a Heated Head attachment included (per Hyperice). The Ekrin B37 counters with 56 lb of stall force (per Ekrin) — within 14 lb of the Hypervolt despite costing over $100 less — five speeds from 1,400 to 3,200 RPM, up to 8 hours of battery life on the v2 versus the Hypervolt’s 4 hours, and a lifetime warranty against Hyperice’s standard terms, all for $229.99. 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, heat, warranty, and price.

Hypervolt vs Ekrin by the numbers
- Price: $229.99 vs $349. The Ekrin B37 undercuts the Hypervolt 3 Pro by about $120 (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: 70 lb vs 56 lb. Hyperice’s March 2026 refresh published stall force for the first time, putting the 3 Pro ahead of Ekrin’s 56 lb; higher stall force means the head resists bogging down when you lean into dense muscle.
- Battery: 4 hours vs up to 8 hours. The Ekrin B37 v2’s lithium-ion pack lasts up to 8 hours per charge (per Ekrin) versus the Hypervolt 3 Pro’s 4 hours (per Hyperice) — a real convenience if you hate charging or share the gun in a household.
- Heat: included vs none. The Hypervolt 3 Pro ships with a Heated Head attachment that warms to 109–120°F, a feature the Ekrin B37 doesn’t offer at any price.
- Warranty: standard vs lifetime. Ekrin’s lifetime warranty is the category benchmark; the Hypervolt 3 refresh improved almost everything else about the lineup but left warranty terms untouched.
- 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, heat, and price rather than results.
Hypervolt 3 Pro — for force, quiet, and built-in heat
Hyperice Hypervolt 3 Pro
- 70 lb of published stall force — the highest Hyperice has ever stated.
- Claimed 51dB QuietGlide motor — one of the quietest guns on the market.
- Heated Head attachment included, warming to 109–120°F.
- Trusted household brand with wide retail support.
The Hypervolt 3 Pro wins on force and refinement. It’s the quieter of the two — quiet enough to use during a phone call or beside a sleeping partner — and the included heated head adds a genuine feature the Ekrin can’t match at any price. If you want the hardest-hitting, quietest experience with heat built in and don’t mind paying a premium for the Hyperice name, the Hypervolt is the more capable tool. See our full Hypervolt 3 Pro review for the complete hands-on breakdown.
Ekrin B37 — for value and battery life
Ekrin Athletics B37
- 56 lb of published stall force — within 14 lb of the $349 Hypervolt 3 Pro.
- Up to 8 hours of battery life on the v2 (USB-PD charging) — double the Hypervolt's 4.
- Angled ergonomic handle that's easy on the wrist.
- Lifetime warranty — the best coverage in its class.
The Ekrin B37 wins on value. It comes within 14 lb of the Hypervolt’s published stall force while costing about $120 less and doubling the battery life, and the lifetime warranty removes the long-term risk that comes with any motor-and-battery device. It skips the heated head and the Hyperice name, but for buyers who care about how hard and how long a gun works and what happens if it breaks in year three, the B37 delivers more massage gun per dollar. And the B37 is just the start of the range — our Ekrin massage gun review covers the whole lineup, from the Kestrel flagship to the 1.1 lb Bantam travel gun.
Which should you buy?
- Buy the Hypervolt 3 Pro if: you want the hardest-hitting published stall force, the quietest operation, a heated head included in the box, and don’t mind paying a premium for a mainstream brand with wide retail support.
- Buy the Ekrin B37 if: you want the most performance per dollar, prioritize battery life and a lifetime warranty, or simply don’t want to spend $349 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 and Theragun vs Ekrin comparisons.
The bottom line
There’s no wrong answer here, but the value gap is hard to ignore. The Ekrin B37 comes within 14 lb of the Hypervolt 3 Pro’s stall force, doubles its battery life, and adds a lifetime warranty for about $120 less, making it the better value for most people. Pay up for the Hypervolt if quiet operation and built-in heat are worth the premium to you; otherwise the Ekrin is the smarter buy.
Updated August 29, 2026 — replaced the discontinued Hypervolt 2 Pro throughout with Hyperice’s current Hypervolt 3 Pro (March 2026 refresh: $349, 70 lb published stall force, 51dB, 4-hour battery, heated head included) and removed a fabricated 14mm amplitude figure — Hyperice does not publish amplitude for any 2026 Hypervolt model.
