Summary: These are Not noise reduction earphones, and they never were advertised as such, but had to put something in the rating. Anyway, I purchased these and received them in a very timely manner. When I got them, the sound was just flat or muddy (take your pick). I tried different ear pieces.
Pros: Crutchfield is easy as all get out to work with, both in ordering and returning products.
As for the earphones - they were comfortable.
Cons: Sound quality. Overall quality - I mean really, the wire came loose.
Summary: Overall these seem like good headphones for athletic purposes but the true test will be durability. I purchased these as an alternative to PowerBeats. I much preferred the Beats sound and fit over the Polk's but after 3 pairs of Beats failed because of sweat, I decided on trying these out.
Summary: Nice phones. They don't sound quite as good as my large Sennheiser cans (obviously) and lag a bit behind my Sennheiser on-ear portables. However, I needed something that would allow me to answer the phone while running/biking. These fit the bill, and the fit is very secure.
Pros: fit, not "great/awesome" but definitely good sound quality. Good fit once you figure it out - phones NEVER fall out of your ears
Cons: Mic ends up a good distance from your mouth when all hooked up. Only an issue while biking, and the provided clip takes care of this. Can take a bit of wrangling before finding the best fit.
Summary: I bought these in ear head phones for listening to music while on long motorcycle road trips . The fit and comfort of them is great , the sound is super . They stay put , are lite to wear and feel good in my ears under my helmet . The sound and bass were way better than I expected .
Pros: Good quality , nice sound and the extra ear pieces and case are nice features .
Cons: I wish the 3 button remote was usable with the short cord .
