I used to be a '320kbps mp3 is good enough' guy when it came to ripping my CD's.
But lately I've been re-ripping some of them to Apple Lossless and listing to them through some decent headphones.
I don't claim to be an audiophile or have golden ears, but it does make a difference.
I was using the Sennheiser MOMENTUM 3 Wireless for a few months already and got the new B&O Beoplay HX today.
I just wish I could merge the two. The Sennheiser has great bass, fold ups (auto turn on/off & pairing as you do so) and has physical controls.
But I find the B&O more comfortable to wear, the headband adjustment is more solid and it has 35 hours of battery life.
I listened to my lossless rips of Morning Musume's '10 My Me' on both of them today and it's like rediscovering that album all over again.
