So I googled Xears since I've never heard of that brand, and I immediately saw this IEM model.
It looks suspiciously similar to my $7 Cliptecs.
And yea they are hella boomy. Sounds like you only have woofers on your speakers and no tweeters. Ok probably a very weak tweeter but you catch my drift.
Avoid like a plague
There's a significant appreciation thread for Xears (http://www.head-fi.org/t/545450/xears-appreciation-thread-formerly-td-iii) which I don't get at all.
The N3i sounded like it had a woofer tuned at 200Hz, and a midrange driver wrapped in blankets.
The XE200Pro added a tweeter to the mix...
