I love the bright colors of these V-Moda's earbuds, but I'm not sure the audio quality can be that great.

Based on what I've read ear bud headphones don't actually cut it compared with sound isolating in ear headphones.

I've been thinking of upgrading my iPod earbuds and would appreciate some advice on the best sounding in ear headphones to get.

I agree about the clarity of [Ultimate Ears Super.fi Pro 5 earphones]: http://www.hifiheadphones.co.uk/ultimate-ears-superfi-pro-earphones-black-prodid-264.html "Ultimate Ears Super.fi Pro 5 earphones". There is also plenty of bass, something that is lacking in the lower end Shure IEM models (SE110 and SE220). The in-ear fit is also really good for my ears with the Ultimate Ear's.

I haven't yet tried a decent set of bluetooth wireless earphones. The box shape things hanging out of your ears with the Etymotic's are a little strange!

Until then I think I'm sticking with regular RF wireless headphones.
