58%of 93 owners recommend
58% recommend · 24% neutral · 18% don't
Owners praise
  • Surprisingly wide, spacious soundstage for a closed-back design, with several owners saying it rivals or beats open-back headphones in this regard
  • Excellent comfort and passive isolation, with soft, deep ear cups and padding many describe as some of the best they've worn
  • Outperforms other closed-backs owners have compared it to, including the DT770, FT1, HDB630, and Noire X
Owners complain about
  • Treble can be harsh, bright, or metallic-sounding, especially in the upper registers and vocals
  • Getting a proper seal and comfortable fit is finicky for some, including a protruding headband anchor piece pressing into the ear cup area
  • Bass can feel weak, anemic, or lacking low-end extension, particularly noticeable for movies and sub-bass-heavy content

  • Classical and orchestral listeners who want spacious, airy presentation over bass slam

What K712 Pro owners say

I keep coming back to them frequently as I love their weight, fit and sound, especially for mixing music.

Recommendation for the AKG 712 Pro, and perhaps tryout the k702 earcups for more detailed sound and wider soundstage.
Bastelkorb on Reddit
the 712 fell way short with boosted bass that created a muddled midrange and a tepid soundstage not as pinpoint accurate and open as the other 7 series.

What Sennheiser HD 620S owners say

Just got my 620s yesterday, I like it, which is saying a lot for a closed back. I think it’s easily one of the best closed back headphones not only in the price range, just in general.
MoonWun_ on Reddit
Crazy enough, the HD800s and the HD620s share the top spot in my endgame headphones. And the price difference is over €1,000. I just can’t believe what the HD620s deliver for €279.
No-Desk-1808 on Reddit
I think technically the 620s but the design of the ear cups means they have this bit that protrudes into the ear cups (I think the anchor for the headband) and it’s quite uncomfortable (at least for me).
