HD 620S

Didn't expect it from the graphs, but the HD 620S became one of their favourite headphones, with good isolation and comfort.

Uses the HD 620S when not on ANC or open cans; it gives good passive isolation.

Their HD 620S sounded better after some break-in time.

The HD 620S's stock tuning isn't the best, but its passive isolation is excellent if it fits well.

Likes the HD 620S a lot: robust build, easy to stretch for comfort, and a clarity in tuning that reveals more detail than most headphones; some sub-bass roll-off on their head, but clearly better than their HD 650.

Compared the HD 620S on a FiiO K7 with the Sivga Oriole, FiiO FT1 Pro and Truthear Hexa on electronica and instrumental tracks, and finds it less immersive: the sound sits in front rather than around them.

“And HD620 sounds a bit less surrounding, like the sound comes more from in front of me than from all sides, the immersion is different, worse, when I change headphones immediatelly and have clear comparison.”

The HD 620S was their first audiophile headphone and they love it for its comfort, isolation, durability and punchy bass, with natural sound on many genres; it isn't as expansive as the HD 800 S.

“HD620S are comfortable, durable, look nice, punchy bass, and many genres sound relatively natural on them especially after letting your ears get used to them. They were my first audiophile headphone and I will defend them to my grave.”
