Sennheiser PC 3 Chat Headset In idle status, a soft sound (~ 750Hz) is höbar I (have broken its earpads) with my old cheap headset could not perceive (and apparently also injects into the microphone, s. Customers image)). By contrast, also the bass come much weaker - in contrast to the heights that schrimmeln violently. If it is only transmitted by phone quality which may well be intolerable. In addition, a volume control missing. However, something more appealing design and gold-plated jack plug does not compensate for these shortcomings - even if it would only cost 5!
