If you want something nicer, you can't really go wrong with the Klipsch S4i. My only beef with them is that they are Y cords, while I prefer J cords (where the cord for the right ear is longer and goes behind the neck). Reviews all over the interwebs.
I have been using genuine apple earbud that came with my iPhone lately. I've used one from bose, but if you don't like it, just stick with the one came with with your phone. It looks the best with the iPhone.
1st what is your budget?
2 what features matter nost
3 what type of music do you listen to?
4 what matters are you into the over driven bass like the Dre's that's why people like them. Or are you looking for good reproduced sound quality.
5 do you want buds like apples or IEM's
6. it's really difficult for people to honestly know your audio likes and needs.
7. mee electronics has a nice range of IEM's and prices also look at shure Panasonic, Sony to name a few and last here is a large review on tons of IEM's
I recently purchased a pair of ultimate Ears 600vi's. Little over a hundred bucks but these are the best I've had so far for in-ears. Multiple silicone and foam tips, super comfortable, and super clear and crisp sounds. Lots of mostly positive reviews on them.
Glad I came across this thread. I still use the factory phones that came in the box...press them in to get better sound and deeper bass. ( I know: that's terrible for my ears) So I'm glad to hear some input on the better choices available.
