Hyperice Hypervolt Heated Head Attachment is the legacy heated massage head designed for compatibility with all Hypervolt models. It adds three selectable heat levels of 43°C, 46°C and 49°C to a compatible Hypervolt device, with a single-button control built into the attachment. This exact MPN is distinct from the newer Heated Head Attachment 3, whose compatibility is limited to the Hypervolt 3 line. The attachment has its own rechargeable power source and is rated for up to 75 minutes of use on the highest heat level. USB-C charging is supported, and a USB-C charging cable is supplied. Because this is an accessory head rather than a massage gun, a compatible Hypervolt is required for percussion operation. The three temperature choices can be selected directly on the attachment, allowing existing Hypervolt owners to add heat without replacing the complete device.
