Came in super fast, sound quality is amazing, very comfortable

The battery life gets me through a full day, they charge quickly and easily, the audio quality is adequate (I have used better headphones but these aren't distracting due to poor quality) , and after some adjustment they are comfortable for a long period of time

Excellent Bluetooth range, great isolation and good sound quality.

Great fit options & awesome sound quality!

Sound quality is pretty horrific

Sound quality was very very bad

The battery on the Sport4 seems to last about 2 hours longer and the sound quality is phenomenal on both, however the Sport4 sounds a bit more crisp and has deeper bass.
