Hi,
 
I'm considering buying the PC 360's and was just wondering what the sound quality can be compared to in other Sennheiser headphones.
 
I've heard from some sources that the driver is the same as hd555/hd595 but other sources tell me it's the same as the hd558/hd598. 
I'm just trying to gauge whether or not it's worth it to get the PC 360's because I would prefer to have better sound quality even if that meant sacrificing the microphone.
 
Thanks a lot.
