Ekrin Athletics B37 Percussion Massager vs Therabody Theragun PRO
Side-by-side comparison of features, pricing, ratings, and alternatives.

The B37 is Ekrin Athletics' benchmark percussion massager and its most popular model, aimed at athletes who want professional-level percussive therapy rather than a novelty device. It pairs a powerful brushless motor with five speed settings chosen to cover the useful range rather than padding a spec sheet, and the amplitude is matched to the power so it actually reaches muscle rather than vibrating the surface. Two practical details separate it from cheaper massage guns: ultra-quiet operation, which makes it usable in a shared space or while watching television, and an eight-hour battery life, so it is not constantly on charge. The angled ergonomic handle reduces wrist strain when reaching your own back and shoulders. Ekrin backs it with a lifetime warranty and sells it alongside the compact Bantam and the higher-end Kestrel.
The Therabody Theragun PRO is a professional-grade percussive therapy massage device designed to provide deep muscle relief and recovery. With a rotating arm and 16mm amplitude, it delivers a powerful and effective massage experience. This device is ideal for professionals and individuals who require intense muscle therapy and recovery.
