These took a little while to get used to but in the end I really liked them.... until (just as another user reported) the left side earpiece stopped working entirely. If you press hard on the outer side of the earpiece, it will engage the sound for about 1/4 second and then go dead again. It's pretty frustrating. I guess I'll have to send them back to JBL for repair

Cant figure out how to install batteries, so, I can't review the noise-cancelling feature.

Initially I was very pleased with these headphones. The sound quality is great, the headband is fairly comfortable (although it has yanked out a few hairs on occassion) and the earphones are very soft and comfortable. I can use them for hours at a time at work. I started to get a bit disappointed when the right headphone started to bend out a bit and made it to where the trackpost which stops the headphones from rotating more the 180 degrees came out of it's groove and it began spinning freely. It was only a minor inconvenience. Now, after owning them for under 2 months the left earpiece has completely stopped working. I will be contacting JBL for a refund or replacement. This is very disappointing for some headphones at this pricepoint.

Just received mine today. Great packaging...great build quality...and even better sound. The live concert mode had mixed reviews online, i thinks its amazing. Better than having to tweak the eq for each song. Very happy...and for this price, its a no brainer.

Have previously been using Beats headphones and these have a much better sound quality. They are slightly larger than I would like as I use them for working out at the gym, but the sound quality makes up for it. Great price for the quality and comfort ability.
