20 W portable Bluetooth speaker

The dotn M17B delivers 20 W of stereo output through a 2.0 driver configuration and Bluetooth 5.4 connectivity. It is aimed at listeners who want a compact, wireless speaker for music, calls or media playback with a 30-metre operating range.

IPX7 waterproof cube with EQ modes

The 5.0-inch cube weighs 1.23 lb and carries an IPX7 rating, so it survives immersion in water. Three EQ presets, a TF card slot and an AUX input give wired and wireless flexibility, while a built-in microphone handles hands-free calls.

Upgrade from basic mono units

Replaces single-driver speakers that lack stereo separation, bass boost or True Wireless Stereo pairing. The jump is worth it when you need 360° sound, 20-hour playback at 50 % volume and RGB lighting that can be toggled off to save power.
