Owners praise
  • Exceptional value for the price, repeatedly called the best bang-for-buck headphone in the hobby, punching well above its price bracket
  • Responds dramatically well to EQ, with many owners saying a modest EQ profile transforms them into a much more detailed, bass-capable headphone
  • Wide, spacious soundstage with strong instrument separation and detail retrieval that owners compare favorably to pricier flagships
Owners complain about
  • 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
  • Bright, sometimes sibilant treble that a meaningful minority finds fatiguing or 'too bright' out of the box
  • Thin sub-bass and lacking low-end impact without EQ, described as anemic by several owners

What HiFiMan Sundara owners say

“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.”

What Sennheiser HD 650 owners say

“What an incredible difference they make to everything I had before! You can listen to a track and hear subtle details that you did not even know they existed. Wow!”
— @marco83 on YouTube
“HD650 with a bum driver, but I was able to solider the voice coil back on, so they work normally again. I had a pair 15 years ago and always regreted selling them.”
— kindofbluetrains on Reddit
“I find the HiFiMan Sundara & the Fiio FT1 Pro both more useful for mixing - the Sennheisers have a much more condensed/flat sound with less bass extension than either of those”
