Very good sound quality, but controls for volume, off/on, and modes are very difficult to use. Volume control on the earbuds is virtually impossible to use. I'm keeping the earbuds but only because of sound quality and comfortable fit. Will just have to use my iphone for any changes in volume.
I made a mistake! I had Senniesers and Sony. My finale decision was based on the ANC. It is slightly better but does a weird thing of amplifier very loud sounds i.e. like a lawnmower would be ok until I turn the lawnmower then I get a short blast of sound. They are really cheaply made esp. the case. The unforgiving part thou is losing connection. Where you have to take them out put back in case ect. They do sound great not as good as the Senniesers and the ANC would be good for commuters. Senniesers app. Is far superior too. I currently use both i do like the bose 3d sound aspect as well.

Hello And thank you for your review, we are glad to hear you are enjoying the immersive audio of your QuietComfort Ultra earbuds.
Excessively noisy environments such as airplanes taking off, concerts, emergency sirens, and construction zones (among others) can overwhelm the microphones used to monitor external frequencies (part of the ANC technology) causing the headphones to crackle or distort. Be aware, this can also happen in Quiet and Aware mode, It is important to know these loud environments will not damage the headphones and there is no lasting damage to the product. If you would like to reduce the amount of times this happens we recommend doing your best to move away from the loud noises.
