“I keep coming back to them frequently as I love their weight, fit and sound, especially for mixing music.”— _crackerjack73_ on Reddit
“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.”— rajmahid on Reddit
“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).”— gussic on Reddit
