This whole thread seems very 'No True Scotsman' and a bit snobbish to me. Labelling the entire $140 - $280 wired headphone range as 'decent' but not 'good' for wired headphones is just ridiculous. Even more so calling every pair Bluetooth headphones below $350 not-even-decent. My Sennheiser PXC 550s (which regularly go for $300 on Amazon) would like to disagree.
There's also a whole lot of outdated information in this thread, e.g. concerning the quality of Bluetooth audio. It's really come a long way.
