- How does the HD 620S differ from the HD 600 and HD 650?
- It is the closed-back model of the family. The HD 600 and HD 650 are open-back and leak sound both ways; the 620S seals the cups for quieter rooms and private listening.
- Do I need an amplifier?
- At 150 ohms it is easier to drive than the 300-ohm HD 600 and HD 650, but a phone jack may still sound thin. A desktop amp or a strong dongle DAC gets the most from it.
- Does it block noise well enough for an office?
- It reduces nearby chatter and keeps your music from leaking, but it is not active noise cancelling. Very loud rooms will still come through.
- What comes in the box?
- The headphones, a 1.8 m cable with a 3.5 mm plug, and a 3.5 to 6.3 mm adapter. No case or balanced cable is included.
- Can I use it for gaming and calls?
- It has no microphone or inline controls, so you would need a separate mic. Its imaging works well for games, but it is built for music listening.
- Are the earpads replaceable?
- The pads are user-replaceable, which matters because artificial leather wears over time.
