Wireless headphones from rockmia. The flexible band allows for various uses, such as wearing around the neck or placing on a desk, adapting to your needs. It can be charged via a USB-C port. It also supports playback of music files from a microSD card (though I haven't tested this). Usage time is about 5 hours. I believe it's in good condition with no noticeable stains. Shipping is planned from Hokkaido via Yu-Yu Mercari. Discounts are available for combined purchases with other items. The EBS-906 is a USB-chargeable neckband speaker, and comes with a convenient storage bag. - Model Name: EBS-906 - Brand Name: rockmix - Included Accessories: USB cable - Storage Bag: Included - Type: Neckband Speaker Thank you for viewing.
