Pocket-sized audio companion

The No Sew B19 Pro is a miniature Bluetooth speaker built for listeners who want music on the move without carrying bulk. At 1.8 inches wide and 1.9 inches tall, it slips into a pocket or small bag and pairs with smartphones, tablets, laptops, televisions and smartwatches over Bluetooth 5.3 for wire-free playback.

Simple wireless integration

The speaker draws power from its internal battery and needs only a Bluetooth source to operate, freeing you from cables and mains sockets. Its 2.0 active configuration means the amplification is built in, so no external amplifier is required. For wider stereo imaging, two units can be linked via TWS by double-tapping the power button, creating a 360° sound field from a pair that still fits in a jacket pocket.

Step up from phone speakers

This unit replaces the tinny built-in drivers of a phone or laptop with a 5W full-range driver that delivers clearer highs and deeper bass for personal listening. The jump is worth it when you need louder, richer sound for podcasts, music or video calls while travelling, at a desk or outdoors. It is not suited for buyers who need room-filling volume, multi-room audio or a built-in voice assistant.
