Gramovox Bluetooth Gramophone

Posted on Mar 12 2015 - 2:21pm by gadgeta

 A Unique Conversation Starter.  A Unique Sound.  Combining Modern Music with the Past.


The Gramovox’s bold design and vintage sound are inspired by the 1920s Magnavox R3 Horn Speaker. Its form and function are a marriage of vintage and modern aesthetics–resulting in a timeless piece that allows you to stream nostalgia.


Works With Any Bluetooth Capable Device.

Gramovox will stream your music from any bluetooth device with a range of over 30 feet!  Remove the cord, take it outside and stream music wireless for 15 hours of battery life!


Gramovox has clearly made the device a premium product, not a throwaway hunk of plastic. For one, the final forms of its horn is made of steel and brass, materials most consumers never thought they’d see in a speaker. Same goes for the device’s wood base, which is sleek, minimal, and juxtaposes well with the curves of the horn.


All of this, Gramovox says, combines to create “an organically mid-range, vintage sound.”
