Three Ways to Listen

The Avantree BTSP-850-BLK combines an FM tuner, a Bluetooth speaker and an SD card MP3 player in one pocket-sized unit. It measures 5.2 in by 1.3 in by 2.6 in and weighs 158 grams. A built-in rechargeable battery charges via USB for portable power. The speaker delivers 2 watts of output tuned for clear voice and balanced audio.

Best for Personal Use

Suits listeners who want a compact device for close-range radio, podcasts or streamed music at home or outdoors. The numeric preset keys 1-9 store favourite FM stations with a long press. Buyers needing room-filling volume, stereo separation or a larger display should look at larger audio systems instead.

2-Watt Mono Speaker

The single driver produces 2 watts, designed for personal listening at arm's length rather than background music across a room. Bluetooth pairing connects phones, tablets or PCs for wireless streaming. The SD slot plays MP3 files directly from a standard card without a separate source device.
