“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

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 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.
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 Momentum 4 Wireless, it's 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.
