My k92 are getting a bit iffy. Right speaker keeps going out, had them open, all connections seem fine, so I guess it's the speaker, so need a replacement. No idea what to replace with though. Usage is mostly games and some youtube. I want closed back (noisy enviroment), over the ear, rather than sitting on it and that's about it. Never used outside, so bulk doesn't really matter. Have a modmic, so not looking for a headset. I use onboard sound. Budget £60ish, but can probably stretch to £100 if it's really worth it. Thanks.
