“I recently purchased the Sony ULT Wear and I love it!”— @jamesbarlett246 on YouTube
“The bass is honestly pretty fun, sometimes I just wanna press a button and destroy the song I'm listening to.”— @Pika915 on YouTube
“To be fair, I didn't hear hardly any difference. The ULTs fit my head better, but they looked much chunkier on my ears as the phones stuck out way more. I've decided to keep the XM4s and return the ULTs.”— @1977ver on YouTube

Owners point the Momentum 4 Wireless at sound-quality-first listeners who'll trade top-tier ANC for richer, fuller audio, and frequent travelers who want multi-day battery life and decent (not best) noise cancellation.
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 Momentum 4 Wireless is aNC is consistently rated weaker than Sony (WH-1000XM3/4/5/6) and Bose competitors, usable for daily commuting but inadequate on planes for some owners. 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.
