Purchased in December 2025. The sound quality is not affected by any malfunctions or wear and tear. However, after using it a few times, the neck speaker's specifications didn't quite suit me, so I'm putting it up for sale. - Purchase Price: 39,600 yen (tax included) - Brand: Panasonic - Model: GNW30 - Included Accessories: All original items (main unit, transmitter, charging cable, instruction manual) - Type: Wireless Neck Speaker - Color: Black ※ I am not very familiar with the equipment, so please confirm the specifications of your monitor or TV for connection compatibility before purchasing. ※ This is a high-end model of the "SC-GNW10S" from the same manufacturer. This model has superior features, so please be aware of the difference. ※ An ELECOM ultra-high-speed HDMI cable (1m) will be included as a bonus. An HDMI cable is not originally included, so I hope you will find it useful. However, please understand that I cannot offer a discount if you do not need it.
