“SR80x (120€ new) was my first audiophile headphone over two years ago. They were so good that within a week I returned them to upgrade to SR225x”— Hunter-97-G on Reddit
“Grado SR80s were my first decent pair of headphones too, and I still love them - still have them and listen to them something like 15 years later.”— srmd22 on Reddit
“Using chinese components. And a lot of glue... You'd think with all that American Engineering, we could not use Glue, and instead use... maybe screws?”— KaosC57 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
