THE Bose QuietComfort 35s are the best wireless headphones I've ever used.
Their noise-cancelling cuts outside din and traffic to almost nothing and they produce crisp and powerful sound.
Unlike other options in the over-ear headphone market the QC35s aren't a fashion statement - they come in plain black or silver. I did have some Bluetooth connectivity issues with the QC35s at times with playback briefly dropping in and out.
Even using the headphones for an hour or two each day the battery lasted more than a week before needing a charge. And if you do run flat they come with an audio cable to plug into your phone. Price $499.
