Casque Sennheiser HD 620S fermé avec isolation acoustique

Excellent balance of virtues : fantastic passive isolation without excessive pressure on the head, soundstage width up there with what you'd expect from open headphones (my closed Audio Technica ATH 1000X Grandioso perform just as well there, but they are nowhere near as good in isolation terms - and although they do sound even more musical with deeper bass, they used to cost twice as much). Top-to-bottom coherence is great, excellent resolution, the mids are rich and detailed and the treble well extended without a trace of harshness. My only gripes so far : I do find the bass a touch recessive, up to and including the mid bass, and front-to-back stage depth isn't as great as left-to-right width. However, I associate both issues to insufficient break-in, so I expect both to improve with time. If you have a home theater setup with a projector - those are ideal : crisp dialogue, widescreen soundstage and great dynamics, PLUS no noise from your beamer. I'm lucky enough that I own a pair of well-broken-in HD800s, and although those play in a different league, I tend to go to the 620s whenever I use the beamer in high lamp mode for 4K content. Recommended.
