^^ This. I've heard a lot of good, some bad, but for $99 for a pair, you can't beat it. If you're looking for SQ and find something that provides that + a higher SPL, then go with that. For loudness & clarity, I'd say go with two sets of the Crescendo's.
My buddy got some and they are loud as crap and sound decent, but I don't think they have the smoothness of my RF T1s.
