Original Rexi brand (Rexi Neckband). Enjoy 120 to 140 hours of continuous music on a single charge, although the company claims 200 hours. The neckband features a display to check battery status directly. You can also use it with a memory card. One charge lasts for a full week. The sound system is excellent, and it is lightweight for comfortable use. Contact me directly if interested. Thanks.
P.S. Selling because I want to buy a waterproof neckband.
