Review: Onyx 4 thumbs up - I love the shape and speakers performance
Review: The best speaker in its class, but - Performance wise: by far the best Bluetooth speaker within its price range / grade and even beyond, crisp sound and deep bass which gives music what it needs. It gets 5 stars easily! Battery: After using the speaker for almost 3 years, it stops working if disconnected from the charger if the volume is above 40-50%, even if the battery is charged. I think the battery went bust, that’s why I gave 4 stars.

### ⭐⭐⭐⭐⭐ Ottimo funzionamento e qualità del suono
*by L***Y on 28 February 2024*

Ho istallato due nella camera e uno nel bagno e ci metterò un terzo nella seconda camera. Il pairing col'iphone funziona perfettamente. Bisogna collegare solo uno al telefono, l-altro si collega tramite un tasto sul speaker al altro speaker. Facile. Il suono é davvero impressionante, un pò bass heavy. Comunque ottimo acquisto.
