Summary: I recommend this product. After a few minutes fitting the Ultrafit 1000 to my ears, the product is comfortable through jogging, and working out in the gym. Sound quality is superior to other products I have used in this price range.
Pros: The cord design resist tangling. Sound quality is great. Overall quality design is apparent in several features.
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: The number one reason I purchased these particular headphones was so they wouldn't fall out of my ears while I run. For that function, they pass with flying colors. I also appreciate the two lengths of chord depending on how I want to use them.
Pros: Headphones stay in ears very well and the different lengths of chords (with remote on the longer chord) help to diversify its capabilities.
Cons: The sound quality suffers greatly from the design of the rubber earpieces and everything sounds muddy with all the high frequencies that get filtered out.
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.
