What to know before buying

Listing details to confirm

The listing details are inconsistent about protection, calling it waterproof and IP67 in the product copy but only water resistant in the specification table. The product listing also gives a 1.6 Pounds weight, while its descriptive copy states 750g, and quotes 30 Watts maximum output without further context. Confirm which configuration and specifications apply to the selected listing. Battery life is claimed at moderate volume, and Auracast is stated to require compatible Android devices.

Customer feedback praises the sound, particularly its reported high fidelity at low volumes, and some describe the value positively. Build quality feedback is mixed, with both favourable and disappointed reactions. For buyers considering a portable speaker for lower-volume listening, the sound comments are relevant, but they do not establish performance across rooms or volume levels. The mixed build comments are worth weighing alongside the listing's conflicting weight and protection details.

Positive themes

Customers praise sound quality, particularly at low volumes.
Some customers report good value for money.

Mixed feedback

Customer feedback on build quality is mixed, ranging from excellent to disappointing.
