The company behind the $399 Nuraphone Bluetooth hearing-correcting headphones have made a new gaming microphone accessory that effectively makes the wireless headphones wired. The microphone costs $49.99 — on top of the somewhat steep cost for the Nuraphone. However, it allows the headphones to plug into anything that accepts a 3.5mm jack, so they can be used with PCs, Macs, mobile devices, the Nintendo Switch, and modern console controllers.
