I have both QC35 from bose and APP. I tried them both on a long flight, while yes, the Bose QC35 is superior in noise cancelling and sound quality, it’s not so much better that I’m willing to dedicate space in my luggage or bag for it. It’s just way too big and I’d much rather carry the APP at just 5% of the volume in my travel bag. The Bose QC earbuds look really nice but at this point, I’m kind of done with Bose headphones and earphones. They are on a strictly quality scale slightly ahead of APP, but they strike out on convenience versus the APP. Now with spatial audio on APP, I’m happy to just go all in on Apple portable audio devices going forward. Now when it comes to home theatre sound, my Bose lifestyle system is incredible and I really enjoy watching movies on that.
