If you don't like ATH-M50 's bass try ATH-TAD 500 it's has has less bass and mid is very good for indie/pop.

Marshall Major born to Rock & Roll

If she don't care about sound quality,you will recommend her Monster Beats,DNA or Crystal Tear

I suggest Logitech UE 9000 , Sennhiser RS 180 , and MM 550-X TRAVEL 

Fiio X5 find  headphoneguru and modify it for better sound.

I  suggest DUNU DN-2000 for a choice

 Denon AH D1100.   I own it and also listen to the same genres as you.   They are $200 on Amazon, but if you shop around you can find a better price.   Very comfortable, great bass and soundstage. Awesome for dnb, dubstep, reggae, etc.   No need for amp.  

I have Ostry KC06 it's sound great like grado sr-60. If you are in the market for a very good pair of IEMs that can compete with phones costing 2-3X as much, get the Ostrys

Panasonic RP-HTX7  best value for under 50$

Havi B3 Pro + Fiio X1+ Fiio E11 = 

LCD-X The Best Full Size Headphone ever.... 

KZ-GK (Spartarcus) is my first KZ 's headphones. Bass is really well but silicones ears tips isn't well.  Can anybody suggest the perfect pair for it?

Thanks for the CK100 review! it's very interesting i will try it.  

waiting for review
