Had the 150's for a couple of years, sound went i left ear after about a year and the right after about 18 months only use them for the mic now but good headset, only downside is that they hurt your ears after and hour or so due to them pressing on your ears all the time. Just bought Sennheiser HD555's and love them. Heard abit about the Medusa's but would get the 150's out of those 2 just because i've had them before.
