This really is a great set of in-ear sport earphones. The noise cancelation is really good, I used it while biking and on public transportation too - had no issue with outside noise. The build quality could be a little bit better, but the lightweight plastic construction is needed so they are lightweight. The fake kevlar-looking insert on them fells off pretty soon (I had two sets of these earphones, that plastic piece lasted a year each time) In my opinion the symmetrical cord wasn't the best choice as an asymmetrical one would be a lot more comfortable and would offer a better fit and not getting tangled while running.
As it was mentioned before me, the comfort is great, the fins keep the earphones in your ears and I don't think sweat could be an issue for anyone. Sound quality is good, detailed mids, bass is good.
Came with a carrying pouch and a set of S/M/L sized fins, no-fin rubber parts, sponges for the canal (to soak up sweat), a tool for swapping the sponge and buds.
