53% recommend · 30% neutral · 17% don't
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.

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.

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!

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.

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
