claim perfect pitch is some sort of qualification, I will too, since you like to use head-fi's reviews. You're dismissing one online reviewer and endorsing another - at the end of the day it's all just guys with opinions and keyboards. It's guys with opinions and different backgrounds in terms of what they own and what they have heard, hence the comment from Mic Cullen about people here on OzBargain knowing what is truly high SQ. Yeah I like this product and I will endorse it if I choose to, people can listen or they can ignore me at their prerogative. It is exactly what I did, without researching further, because I saw your 'urinate over cx300s' comment and decided to try out the m4s. As I said, not sure if your comment is based purely on the cx150, cx300 and a pair of m4s that you have owned, or maybe the m4s I currently own are duds (and if this is the case, looks like I'm not the only one, quality control issues maybe), or they really are just bad, talked up by people who only own $30 audio equipment (low standards/expectations). People can also choose to read what I post. Audio equipment currently in my hands: sennheiser hd228, audio technica ath-m50s, sennheiser cx300, feels pro 900, brainwavz m4 (mic, burned in) I don't claim to be an audiophile, but the way I see M4s being talked up in OzB is a bit concerning. At this point in time
