Select owners of Guitar Hero III for Wii have been moshing uncontrollably as best they can in mono for months on end, but it seems as if Activision has finally got its interconnects sorted and will start issuing replacement discs. According to direct end-user reports and the (admittedly blurry) shots in the gallery below, the firm is now dishing out pre-paid envelopes in which customers have to ship back their faulty GH III disc and wait "3 to 4 weeks" before getting a new, stereo-enabled one free of charge. Live sans your favorite game for a month, or keep rockin' in the monaural world? Tough call, indeed.

Those tired of buying a proprietary adapter for each and every audio source they'd like to make wireless need look no further than Casuh, who has apparently conjured up an end-all solution to multiple audio sources funneling into a single wireless headset. The Joyfon headphones utilize the firm's Retaw-1 chip to communicate with transceivers that can plug into any audio source with an auxiliary output, giving users the ability to toggle between sources sans the fuss. Additionally, it looks like you can take a listen at multiple audio streams (hey, nothing wrong with a little Yeah Yeah Yeahs to drown out a recorded lecture), and it can even be used to hold conversations with other Joyfon users. Check it out in a bit more detail after the jump.
