Sennheiser HD 620s
The Sennheiser HD 620S is a wired, closed-back over-ear that aims to deliver an open-back-like soundstage and imaging for its price range. Its tuning is largely neutral with a slight low-end emphasis, while its high impedance and sensitivity make it flexible with various amplifiers, though its weight and fit-dependent response are notable trade-offs. Overall, it earns praise as a capable mid-priced option for those seeking a natural, detailed closed-back experience.
- Pro:Balanced, natural tuning with minimal harshness
- Pro:Impressive soundstage width for a closed-back design
- Pro:Strong sub-bass extension and dynamic punch
- Con:Heavy build may cause fatigue over long periods
