ok from past experience, the sennheisers CX-300 II, cheap with an awesome sound, but watch out, its fragile (price you pay i guess), mine broke after about 6-7 months? gutted! please also watch out for all the fakes out there, be sure to buy it from a known supplier.
I've ordered a pair of Denons...should arrive soon, will get back to you on that one with a review lol
Edit: ooooo! they arrived! I got a pair of Denon AH-C260's. comfy, nice range of earbuds, simple, 1st track i tested this against was Pendulum - Masochist. its a lil quiet on normal effects, bass doesnt seem to be totally there but man that SRS effect on our phones make a difference with D&B tracks.
2nd track: Professor Green - Jungle, same as the above, when no effects is on its a lil short on the lower levels, but SRS sorts that out big style!
3rd Track: Lamb of God - In your Words, same as the above 2....turn on SRS and your a happy bunny
so yeah...its a lil lacking on the bass but ive been told that the build quality is alot better on these. dont get me wrong, the sennheisers cx300's were awesome , but i dont want to keep paying
