i own the sd2s and the fitear tg334. i find they compliment each other. :) one good for sleeping and one good for serious listening. they both share the same sig - mid focused, but still they differ to each other generally. yes, the inear stagediver iems are the best iem that fits any ear :) its like having a univeral in a custom form.
