Bose QuietComfort Ultra Wireless Noise Cancelling Headphones with Spatial Audio, Over-The-Ear Headphones with Mic, Up to 24 Hours of Battery Life (QuietComfort Ultra, Sandstone)

I work in an office that has a fan blowing overhead all day long. It’s never quiet. The first time I put these on it was a little creepy how silent it was. My coworker could not tolerate the silence. I love the noise cancelling obviously and the app is easy to use and adjust. The battery is not as long as I would have expected however I do not need it to last 24 hours before its next charge. I love the 2 connections for Bluetooth at work so I can make calls and it switches back to my audiobook. Makes my day even more efficient.

I made the mistake of assuming that these would be similar in functionality to my QC-35s. If you connect an audio cable, the headphones still need to be powered on. Additionally, the sound coming back from a connected audio interface monitor is not clean - more like a gated reverb that might have something to do with its immersion audio technology (which, in of itself is cool).

Nice headphones, overall good audio (though no better than my wired Sony MDR-7506s). The noise cancellation is superior to any other I've used.Generally quite comfortable, but not great with eyeglasses.Software issues:1) The app sucks. Limited number of presets and you cannot rename any of them.2) The headphones sleep instantly when taken off. Unfortunately, even momentary interruption, like adjusting them for comfort, can send them into sleep. That might not be so bad, except there is a lag of a few seconds while they reestablish a Bluetooth signal, at which point you get another 8 seconds or so of a computer voice reporting battery charge and naming all devices it is presently connected to. Same drill, of course, when you deliberately pause the signal. This gets really old, really fast, and I wish there were some way to disable that so-called feature.

Absolutely love them!!! The noise canceling is amazing. I don’t hear anything in the background when I have them on. The sound is incredible as well!! They connect quickly to my phone and I love that when I take them off they pause my music. Absolutely love them and I cannot recommend them enough!
