## Less suited to

- Buyers prioritising a particularly lightweight speaker for frequent carrying.
- Anyone who needs a guaranteed 25-hour runtime or verified performance under specific listening conditions.

## Customer feedback

Customer feedback praises sound quality, especially punchy bass, and Bluetooth connectivity. Battery life and weight draw mixed reactions. This matters for buyers who plan long sessions away from a charger or expect to carry the speaker often. The listing's 25-hour battery claim is not a guarantee, and the stated weight is 4 Kilograms.
- Positive themes: Customers praise the sound quality, particularly the punchy bass.
- Positive themes: Bluetooth connectivity is appreciated. One customer reports using it with a non-Bluetooth music keyboard.
- Mixed feedback: Battery-life feedback is mixed, with some customers saying it falls short of the advertised 25 hours.
- Mixed feedback: Weight feedback is mixed, with customers describing the speaker as heavy.

## Frequently asked questions

The listing claims 25 hours. Customer feedback is mixed, and some report that it does not reach that figure, so treat it as a claimed maximum rather than guaranteed runtime.

### What comes in the box?
The listed contents are a shoulder strap and a USB cable \(C to C\).
