I broke the headphones that came with my Bush DAB radio (trapped in the car door). Was this a disaster? No way! I bought a pair of these to replace them on impulse (at Richer Sounds in Prestwich). The difference is incredible! Not only does my DAB radio sound much better but the MP3's on the laptop and on my CD/MP3 player sound twice as good!
I'm not an audiophile so the difference must be massive for me to notice it so much!
So...trap your current headphones in the car door and buy some of these. You won't regret it!
