Best sounding earbuds

Just bought a new phone that have FM radio and MP3 player, and was wondering if you guys recommend any earbuds that sound good on the go.

The price shouldn't be higher than what I paid ($40) for the phone :D

Opinions may differ, but I've got a couple of these Sennheiser CX300's and they fit the bill perfectly, IMNSHO. But, then again, I've never been dissatisfied with any of the other Sennheiser earbuds I've owned over the years.

...and the price is right.

Panasonic RPHJE120K Shockingly good at this price.

Thanks Mark and Ardy

I went by the store today (no names :D), and really not much selection. They either had $5 cheap brands or expensive Monster brand with not much in between. So may opt for buying online.

The price for Sennheiser look good, so does Panasonic review for for such a low price.

Dunno if you still look for them but I'd always recommend Creative earbuds. I've tested many and these were always the best!

You could try these. I got a pair for my Sansa ClipZip. They are better than I thought they'd be.
