Choose a portable speaker with both wireless and stored-music routes. The S51 design lists 10W output, Bluetooth 5.2 and support for USB and TF-card playback.
Stream from a nearby device or load a stored playlist when that suits the session. The battery and audio entries give you specific figures to compare, while the portable design lets you arrange the speaker where you want the music.
TF-card and USB playback give the S51 routes for stored music as well as Bluetooth. Confirm supported file and storage formats, then choose the source that fits your listening session.
02
Wireless audio where you place it
Bluetooth 5.2 connects a compatible device to the speaker without an audio lead between them. Keep the source within a suitable range and account for walls or other obstructions.
03
A separate speaker for your changing setup
The portable format lets you move the audio between a desk, shelf or other listening spot. Check its full dimensions and charging needs before planning how it travels with you.
