True. Even the Sennheiser PC 360 I bought (touted as the greatest) had serious issues related to the microphone.
I think the only worthwhile headset I've ever had was an old USB Plantronics Gamecom.
All cheap headsets have been a waste of money (terrible sound, non-functional mic).
I'm thinking perhaps it's time to just buy splurge on an expensive mic separately and forget the headset.
They don't make them near as durable anymore for what you pay.
