Each piece of music can be a masterpiece which is why the speaker it comes out of should be, too. Enter the Tube Audio Bluetooth Speaker from Leff Amsterdam. A result of a design partnership with Piet Hein Eek, a Dutch furniture studio, this speaker is equal parts form and function. The Tube Audio Speaker; which is available in brass, copper, and steel; was made to be identical to the Tube Clocks of the same brand. When paired, the speaker and clock produce a stunning symmetry to your table or desk. Pairing with your tablet, smartphone, or computer, the Tube Audio Speaker pumps out music at up to 100dB to blow you away. Additionally, the lithium-polymer battery packs enough juice to play for 12 hours.
