“i'd say go for the Beyerdynamics since their only drawback is their harsh upper register of the frequency and nothing else. For the money, you can't beat them!”— chrissb34 on Reddit
“dt 770 100% and hyperx quadcast microphone! Best combo ever and "cheap"”— NervousNobody666 on Reddit
“The long term durability of these headphones seems to really depend on the climate where you live. When I moved to Florida the humidity and/or heat really caused them to start deteriorating fast.”— Lord_swarley on Reddit
“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
Real owners rate these about evenly: 55% of 197 DT 770 Pro owners recommend it, vs 53% of 352 for the HiFiMan Sundara.
Owners point the DT 770 Pro at gamers and FPS players wanting wide, precise soundstage in a closed-back set, and home studio mixers/producers who value detail and don't mind a bright signature.
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.
The most-cited downside of the DT 770 Pro is sharp, peaky treble (the well-known 'Beyer treble') that many find harsh, sibilant, or fatiguing, sometimes causing headaches after 10-15 minutes. For the HiFiMan Sundara, it's 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.
