Excellent comfort and passive isolation, with soft, deep ear cups and padding many describe as some of the best they've worn

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).”

What Sony ULT Wear owners say

“I recently purchased the Sony ULT Wear and I love it!”
— @jamesbarlett246 on YouTube

“The bass is honestly pretty fun, sometimes I just wanna press a button and destroy the song I'm listening to.”
— @Pika915 on YouTube

“To be fair, I didn't hear hardly any difference. The ULTs fit my head better, but they looked much chunkier on my ears as the phones stuck out way more. I've decided to keep the XM4s and return the ULTs.”
