AWESOME SOUND – The speaker produces all the highs and mids you’d expect from a Hi-Fidelity speaker of its size. While attached to the Tumbler, users can feel the beat of the music. Remove the speaker and use it in the shower as an added use. TRAVEL USE – Designed to fit in any standard car cupholder so you can bring it with you with or without the detachable speaker. The handle ensures a solid grip while holding.
