The Fender x Teufel Rockster Go 2 is the sole portable Bluetooth speaker we’ve tested under $100 that comes near to the sound of an honest bookshelf speaker.

Value: This small speaker represents excellent value. https://www.bluetoothspeaker.top/tws-speaker-stereo-sound-bluetooth-speakers-china-factory-high-quality/
