★Weekend Sale★ Bluetooth neck speaker. Includes a receiver, so it can be used with older devices like the Nintendo DS that don't have Bluetooth. The receiver needs power via USB. You can use a power adapter to plug it into a wall outlet. Works perfectly, but it's a used item, so there may be some scratches or dirt on the exterior. Recommended for those who don't mind minor imperfections. Instruction manual included. #WearableSpeaker #NeckSpeaker #Earphones #Bluetooth
