Choose it if…

You want game sound and voice chat in one headset.
You are happy to check your voice with your chat app’s mic test instead of hearing yourself continuously in headphones.
You want a wearable microphone rather than a separate desk stand or arm.

Before choosing this model

On a console you use the adapter in the box; beyerdynamic sells a 1.2 m console cable separately.
beyerdynamic warns never to plug the mic into an input with phantom power (12 to 48 V): it damages the mic.
beyerdynamic names Switch, not Switch 2.
It plugs in by cable, so there's no edition to match: use a jack that takes a headset mic, such as a controller's 3.5 mm jack.
No stand or arm needed: the mic is on the headset.
Use the cable in the box; you only need an adapter if your computer lacks that port.
