Query: Better than your average headphones

They're certainly better than the average earphones, but don't confuse them with noise-cancelling headphones. These are noise-isolating earphones which means they don't have the microphone/electronics to produce an opposing frequency to cancel out ambient noise. These earphones, and all other noise-isolating earphones, rely on the removable ear pieces to block ambient noise. With that said, I think these do a great job when using the right ear piece.They come with three different types of ear pieces. I found that the foam ones did the best job of blocking ambient noise. My main issue with the headphones is that they have absolutely NO bass. I don't really "bump" my music, or really listen to music that relies heavily on it, but it's noticeable.I paid about $70 for this pair. $50 would have been more reasonable.
