iPod Headphones: What Do You Use?

I've enjoyed my new iPod for a couple of weeks now. The iPod is an "insanely great" audio player but, now that I've used it for a while, I want to replace the standard headphones. There are a couple of reasons for this:

• I find the supplied in-ear set very uncomfortable, particularly after extended use
• Having tried the iPod with my hi-fi headphones, I know that even better sound is available with the right set
• I don't want to advertise the fact that I'm walking round with £400 worth of audio equipment in my pocket

However, when it comes to finding a replacement, I am spoilt for choice.

So my question, to iPod users far and wide, is this: What headphones do you use with your iPod?
