“They won't break. I've got a opair of the 2020 Sundara's and a recently purchased set of Arya Stealth. They're both perfect. Sound wise and build quality too.”— Kevbassman on Reddit
“Absolutely the Sundara gives you way more than its price suggests clean planar bass, great detail and a neutral tuning that honestly captures most of what people love about higher end cans.”— Ornery-Ad-9419 on Reddit
“I think the. Sundara is super overrated. It's fine, nothing special, has some quirks/problems that many better headphones in and above its class don't.”— drwafflefingers on Reddit
“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
Real owners lean toward the HiFiMan Sundara: 53% of 352 owners recommend it, vs 47% of 154 for the Sony ULT Wear.
Owners point the HiFiMan Sundara at budget-conscious audiophiles wanting near-flagship detail and soundstage for a fraction of the price, and listeners willing to EQ, since owners say a bass shelf and treble tweaks transform the sound.
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 HiFiMan Sundara is inconsistent build quality and QC, owners report cracked headbands, dead or channel-imbalanced drivers, and units failing anywhere from days to a couple years in. 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.
