Independent shopping perspective
The Korena take
HD 620S are wired, closed-back over-ear headphones built for focused listening without giving up a broad, speaker-like presentation. Their angled 42 mm dynamic transducers are designed to present detailed, naturally balanced music, including substantial yet controlled bass and clear handling of complex tracks. Artificial-leather earpads, spacious earcups, and a 326 g cable-free weight support long sessions. The detachable 1.8 m cable terminates in 3.5 mm, with a 6.3 mm adapter included.
Strong match
Who this is for
- Focused extended listening sessions where a closed-back, over-ear design helps keep attention on the music.
- Connecting to a 3.5 mm source or a 6.3 mm headphone output with the included adapter.
- Listening closely to complex tracks, vocals, instruments, classical music, or rock.
Consider the trade-offs
When to look elsewhere
- Listeners seeking a wireless headphone design.
- Setups that require a balanced connection without adding the optional 4.4 mm balanced cable.
