- Does the HD 620S need an amplifier?
- No. At 150 ohms and 110 dB sensitivity it reaches good volume from a phone or laptop. A USB dongle or desktop amp gives cleaner bass and more headroom.
- How is it different from the HD 600?
- Same family tuning, but closed cups for isolation and less sound leakage. The trade-off is a narrower soundstage and more weight.
- Can I use it for calls and gaming?
- Yes, with the cable's inline mic or a separate mic. The closed design keeps game audio from leaking, and the neutral tuning suits voice.
- Are the earpads replaceable?
- Yes. The artificial leather pads and headband padding are user-replaceable, which extends the headphone's life.
- Does it fold for travel?
- No. The cups do not fold and the frame is bulky, so it is best kept at a desk or at home.
- Does it have noise cancellation?
- No. It relies on passive isolation from the closed cups, which cuts some room noise but not engine or fan drone.
