Re: Buy Koss -> please do not.
Please, do the responsible thing and do not get the Koss Porta Pro. For the money, they are really good, fun-sounding phones and Koss provides a great warranty. They are also as open as the arms of a seamstress on duty and leak more to the public than the most proficient whistleblowers. So if you use them on any sort of shared transport, other people will hate you. A lot.
