Q90B Portable Bluetooth 5.3 Speaker

The dotn Q90B is a compact wireless speaker that pairs a 40 mm driver with a four-unit cavity design to produce 360-degree stereo sound. Bluetooth 5.3 provides a stable link up to 15 metres away, while the built-in microphone enables hands-free calls. A suction cup mount and IPX7-rated shell let it cling to wet tiles or glass without damage.

Bathroom listeners and outdoor users

Buyers who want a lightweight speaker for showers, beach trips or car cupholders will appreciate the eight-hour battery and the LED light show that pulses to the music. The single 5-watt unit cannot fill large rooms or deliver audiophile-grade separation, so home-theatre enthusiasts or party hosts needing high output should look elsewhere.

Bluetooth 5.3 with 15-metre range

The sole connection method is Bluetooth 5.3; there is no auxiliary input, USB audio or Wi-Fi streaming. If your source device lacks Bluetooth or you require a wired fallback, this speaker will not integrate with your setup.

Questions about this item

Will the dotn Q90B connect reliably to my older phone using its Bluetooth 5.3 link at 15 metres?

The speaker uses Bluetooth 5.3 with a stated operating range of 15 metres, which is backward compatible with earlier Bluetooth phones and maintains a stable link within that distance.

How can I confirm the dotn Q90B is working correctly after I pair it and attach the suction cup?

After pairing, play audio and verify sound comes from the 40 mm dual bass diaphragms, check that the LED light cycles through its seven colour themes, and ensure the suction cup holds the speaker firmly on a smooth surface.

What comes in the box with the dotn Q90B and what must I supply myself?

The package includes the speaker, a suction cup, a Type-C charging cable and a user manual; you will need to provide a USB power source such as a wall adapter or power bank for charging.
