PingPangBV, dragoonk. My stereo Sennheisers were a similar price and similrly plastc. Good quality plastic but plasticall the same. The microphone, can people hear what you are saying?. That is all I would want from a mike. They get the important thing right, there ain't nought wrong with the listening! Sure you you can get three of that and half a dozen of the other for the price, but I live in a flat. I have had to force out two douches wtth no regard for their neighbours and I like my music loud. I have to pay good money for a decent headphone exsperience. The buzzing being picked up is a probably a ground/shielding problem, and as likely down to the sockets in your case as anything else. Once it has been superimposed on the waveform the drivers are getting, there might not be a lot to be done about it. You could include a notch filter in the headphones, but that would equally take out audio at those frequencies as well. Is it all the ports? Is it intermittent? If you are using a front port for convenience, I wouldn't be surprised if the cable isn't shielded at all. As I said my stereo Sennheisers were a similar price and you agree this very good kit where it counts. How much would ironing out the little niggles bump up the price? This isn't negative criticism for either of you. I have an eliectrical engineering background and have suffered a lot from noise pollution.
