Real owners lean toward the Sony ULT Wear: 47% of 154 owners recommend it, vs 36% of 434 for the Bose QuietComfort Ultra Headphones (2nd Gen).
Owners point the Bose QuietComfort Ultra Headphones (2nd Gen) at frequent flyers who want quiet on a plane and a case that fits a carry-on, and glasses wearers and anyone whose head hurts in tighter-clamping headphones.
Owners point the Sony ULT Wear at bass lovers who want heavy, adjustable low end, and buyers who want strong noise canceling without paying flagship prices.
The most-cited downside of the Bose QuietComfort Ultra Headphones (2nd Gen) is a background hiss or white noise floor with nothing playing, audible to many owners though not all. For the Sony ULT Wear, it's plastic hinges that crack or snap, often during normal handling, anywhere from a few weeks to over a year after purchase; some owners had a second pair break the same way, while others say a replacement has held up.
