Description
A passive bamboo phone dock that boosts your speaker without any electronics.
Drop the phone into the slot and the hollow bamboo chamber directs the speaker output forward and amplifies it — the same resonance physics behind acoustic instruments. No batteries, no Bluetooth, no charging: louder sound for music, podcasts and speaker calls at the desk or kitchen counter.
Real bamboo with an internal acoustic channel. Fits most smartphones. Wipe with a damp cloth; keep liquid out of the channel.
