Question 1

Are these headphones good for gaming, and do I need a separate microphone?**

Accepted Answer

Absolutely. Many users on gaming forums praise the HD 620S for immersive single-player and story-driven games due to their natural spatial imaging. For competitive gaming, the accurate sound helps, but dedicated "gaming" headsets might emphasize positional cues more. You will need a separate microphone, as these are purely audiophile headphones. A simple desktop mic or an attachable modmic works perfectly.

Question 2

How is the comfort for all-day use, especially with glasses?**

Accepted Answer

Comfort is a major highlight. The velour ear pads and lightweight design are built for long sessions. Note that some users with glasses or larger heads mention a firm initial clamp force. This typically loosens up after a few days of use. The consensus is that once broken in, they disappear on your head, making them ideal for extended work, editing, or listening.

Question 3

Do I need a special amplifier to use these?**

Accepted Answer

While the HD 620S are more efficient than some classic audiophile headphones, they truly shine with a dedicated headphone amplifier. You can drive them from a phone or computer, but a good amp (even an affordable DAC/Amp combo) will provide more control, dynamic range, and volume headroom, unlocking their full potential for detailed, low-distortion sound.

Question 4

What's the deal with the cable, and are there upgrade options?**

Accepted Answer

The included cable uses a 2.5mm twist-lock connection. Some Reddit users have noted it can feel a bit delicate when connecting/disconnecting, and the cable itself can transmit rustling noises if it rubs against your clothes. The good news is the cable is detachable! A vibrant aftermarket exists for upgraded cables (including balanced options) from brands like Hart Audio Cables or Periapt, which many enthusiasts recommend for improved durability and microphonics.

Question 5

How do these compare to the famous open-back Sennheiser HD 600 series?**

Accepted Answer

This is a key question from audiophile communities. The HD 620S is designed to bring the neutral, natural tonality of the HD 600 series into a closed-back design. The main trade-off is soundstage: open-backs like the HD 600 have a more expansive, airy feel. The HD 620S counters with impressive (for a closed-back) spatial imaging and the crucial benefit of noise isolation. If you need to block sound in or out, the 620S is the clear choice. If you listen in a quiet room and want the absolute most open sound, the classic HD 600/650 remains king.
