PS5 Compatible SONY Headphones - Junk

This is a SONY headset that was used with a PS5. The sound output is fine, but the microphone does not work.
Please note that this headset cannot be used by those who need the microphone function.

The original purchase price was around 9,000 yen.

This is a used item, and we ask that only those who understand this and are comfortable with amateur assessment and storage purchase. Thank you.
