The Hammerhead Pro v2 In-Ear Headphones from Razer has been redesigned and features an improved body with a tangle-free flat cable for mobility and easy storage when you're on the move. Its large 10mm dynamic drivers deliver acoustic clarity and improved bass performance thanks to an optimized inner acoustics chamber. Furthermore, an in-line microphone and audio controls provide you with additional functionality and convenience. These controls are fully functional on iOS devices with a 3.5mm combo jack; however, functionality on other devices may vary. As it uses a standard 3.5mm connector, the Hammerhead Pro v2 is widely compatible with most portable audio, mobile, and computing devices. Included are replacement ear tips of varying sizes and a carrying case.
