The sound quality is fantastic, great bass, just enough and doesn't overpower the vocal and treble. At first, the build quality of the earphones look a bit plasticy and cheap but are actually very strong, the earphones aren't fingerprint resistant though. Nice right angled jack so it won't get stuffed in your pocket and also comes with the handy case for protection.
Wouldn't recommend for running, the cable rustles and sounds horrible. The noise isolation is excellent. Very effective, especially with music going, looking forward to using them to walk to school tomorrow! The different ear cushions are very helpful, only one of each though. They are very comfortable when you find the right ones, just trial and error. I found myself using different sizes on each ear too! XS on my right and S on my left! The foam ones are also very comfortable but not as effective for noise isolation.
