I have a new pair of tf 10s and planning to reshell them  from kozee but since kozee already sells infinity x2 i was wondering which one would be better considering both costs the same.. Any info would be highly appreciated..    ** you can also suggest other custom iem for $299  price 

I have a budget around $200-$250 .. Will use smartphone as my source..usually listen to trance , progressive , rock..  Any input will be greately appreciated. I have never owned any earphones costs more than $40.. Looking for something with detailed sound and with great bass..  Over the ear...
