The AULA BS303 is a mini portable Bluetooth 5.3 speaker with a 40mm driver, a 600mAh battery that charges over USB-C, and a transparent shell with a rhythmic light bar. It suits anyone who wants a small, colorful speaker for a desk, nightstand or bag.
Who the AULA BS303 is for
Desks and nightstands: The transparent PC shell shows the 40mm driver and circuit board, with a VU-style light bar that AULA calls rhythmic lighting.
Phones, tablets and laptops: Bluetooth 5.3 pairs with most Bluetooth phones, tablets and computers, with a rated range of up to 10m (33 ft).
Grab-and-go listening: A braided carry loop on top and a 600mAh battery that recharges over USB-C make it easy to move from room to room.
Matching your setup: Five colors (Orange, Purple, Blue, Black and Mint Green) share the same see-through shell and carry loop.
Skip it if: you need a rugged outdoor speaker or a rated play time; AULA lists no water-resistance rating or battery hours for the BS303.
