Logitech Wireless Headset H600. This product uses a proprietary USB dongle for wireless connection, not Bluetooth. I used this headset and another pair of headphones interchangeably for about 3 years. I'm selling it because I don't use it as much anymore due to changes in my home environment. There is some wear and tear, such as scratches on the plastic, from age and use, but all parts function without issue. The charging cable is not included. Two new ear pad sponges (third-party) are included. It will be shipped via Rakuraku Mercari delivery in a cardboard box. Instant purchase is welcome. Thank you.
