Happy to have found these to replace my Bose Quiet Comfort 15s. I am a regular business traveller, musician and swim-dad. These Cowin E8s are next generation! Their noise cancelling is superior to Bose in my opinion. The around the ear comfort is also better with softer padding and a less-tight/lighter-sitting design. The active noise cancelling tech is great, especially in swim meet venues where the ambient noise is very loud and echo-y. Sound quality is good and I use these to play and practice in my home studio. The volume control buttons are on the small side so folks with bigger hands/fingers like me may have more mis-hits. Not a huge deal though. The case is bigger than the Bose so take that into account when packing/traveling your cary-on bag. The case fits nicely into my rolling computer bag. Bluetooth paired easily with my phone for listening to music, audiobooks and podcasts. I liked these so much that I bought another pair for my wife!.
