“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
“I then connected them to my android phone and everything was much crisper and detailed because it used LDAC. I then also played around with the equalizer and now they sound much better.”— Alanwake28 on Reddit
“Using XM3 daily since before covid, only headphone I own and do everything you say we shouldn't. Through pouring rain, snowstorms, at the gym, at my factory, stuffed into bags.”— electro_lytes on Reddit
“The issue I have with the Sony XM6 headphones is that they tend to cause my ears to become warm and sweaty, especially during extended use. This discomfort can be quite distracting”— No-Seaworthiness7880 on Reddit
Real owners lean toward the Sennheiser HD 620S: 58% of 93 owners recommend it, vs 35% of 571 for the Sony WH-1000XM6.
Owners point the Sennheiser HD 620S at gamers wanting a closed-back with wide soundstage for competitive FPS, and office/WFH users needing strong passive isolation from surrounding noise.
Owners point the Sony WH-1000XM6 at commuters and travelers who want class-leading ANC for trains, planes, and noisy offices, and listeners willing to tweak the 10-band EQ, since many say default tuning is flat until adjusted.
The most-cited downside of the Sennheiser HD 620S is treble can be harsh, bright, or metallic-sounding, especially in the upper registers and vocals. For the Sony WH-1000XM6, it's hinges and headband can crack or snap outright, sometimes within months, and owners report Sony denying warranty repair or charging for it.
