Buy the Theragun Prime if you want a deeper, harder, more percussive stroke and the signature triangle grip — it is the gun for dense muscle and people who like to feel the pressure. Buy the Hyperice Hypervolt 2 if you want a quieter, smoother, lighter gun that is more comfortable for everyday recovery. Both are excellent mid-range guns from the two biggest names; they simply feel different, and that difference is the whole decision.
One generation note before the specs. Hyperice launched the Hypervolt 3 line in March 2026 — the Hypervolt Go 3, the Hypervolt 3 and the Hypervolt 3 Pro — and the standard Hypervolt 3 is the current version of the gun compared here. It answers the two criticisms below directly: Hyperice now publishes a 12 mm amplitude and a 60 lb stall force for it, it moves from three speeds to five, and battery is rated at about four hours. The Hypervolt 2 is still widely sold and everything we say about it is still accurate, so this comparison holds if that is the gun in front of you — but if you are buying new, compare the Prime against the Hypervolt 3 rather than the 2. We rank the Hypervolt Go 3 in our best massage guns roundup.
The Prime's headline is its 16 mm amplitude — a long, deep stroke that penetrates big muscles and feels genuinely intense. The Hypervolt 2 does not publish an amplitude figure, and in practice its stroke is shorter and its defining trait is QuietGlide smoothness: it is one of the more pleasant guns to actually hold and use. Below is the honest spec comparison, then the verdict for each type of buyer. If neither brand's premium appeals, our best massage guns roundup has quieter, harder-hitting guns for less, and are massage guns worth it? covers whether either is the right spend at all.

The verdict
Buy the Theragun Prime if you are a bigger or more muscular user, you do deep deep-tissue work, you like to actually feel the percussion, or you want the triangle handle to reach your own back and shoulders. The 16 mm stroke and rugged build are its reasons to exist.
Buy the Hypervolt 2 if you want the quietest, smoothest, most comfortable everyday gun, you value a lighter body and longer battery, or the built-in pressure sensor and a gentler stroke appeal to you. It is the easier gun to live with — and it typically costs less, which only sharpens its case.
How we picked
Everyone in this category says they tested twenty products. We have not lab-tested any of these, and we say so. What we did instead: compiled the published specifications, pulled the numbers from the manufacturer manuals, ran the cost-to-run and cost-per-unit math where there was math to run, and scored each product against a published rubric. The scores are judgments from documented research — not measurements we took, because we do not have a lab and we will not pretend we do. Where a number came from someone else's work, we name them in Sources.
