The Ultimate Ears UE-11 Pro. I got a pair by working for it, instead of actually getting any money. I got a pretty good deal because of this, and that is the only reason I could afford them, which is the main problem: These buggers will cost you.

But it is worth it. The sound is unlike any other set of earphones. There is space for each and every instrument you add, and they perform best with recordings of (Or, if you are like me, actual) live situations, and nothing compares to the time I plugged them into the wireless monitors the musicians themselves were using. It proved to me that four drivers are worth it. The sound, the impact, the detail and yet the musicality stunned me and still stuns me even with my lowly recorded music. They speak a different language, but it is a language that I can not help but enjoy. They are nothing like regular, full-sized headphones, but they sure as hell compete with them in terms of providing a completely right sound.

They are not called Ultimate for no reason.

Ultimate Ears UE 11 Pro Review

this is my first review on headphone reviews. i owned a lot of headphones and tested almost high end headphones on the market ,just real audiophile.UE 11 is not the most expensive i tested but it sound better than the more expensive ones like em3 earsonics,at first let me tell that the included accessories are perfect and 11 pro come in complete package.most headphones have different taste to different genre.but i feel 11 pro fits best for everything you play.the bass for UE 11 is very fast.11 pro do the bass as ts expected from the recorder. and also it is not artificial,really what we can dream of,the 11 pro's midrange is the best i ever heard and somehow how it never exaggerate the midrange i think its good point for professional to hear the exact midrange and maybe bad thing for other people that they want to repair midrange by their headphones,the treble is fast too bud but 11 pro is not standing there for treble, but maybe you like that when your headphone do not hit you with treble its personal taste i also don't prefer to have very strong treble,if the treble is necessary for you go for something else.i know some better ones for full size headphones but 11 pro is the best in midrange and treble among canal ones.the beast earphone money can buy is the 11 pro,but you may find better thing in bass treble ,bass midrange but never in canal earphones maybe just in full size headphones
