Inspired by mid-century modern architecture, the Crosley Octave Bluetooth speaker is truly a functional piece of art for your home or office. The walnut veneer lends richness, while the heather gray speaker cloth adds texture and vintage appeal. Gold-tone hardware rounds out the Octave's sophistication. In addition to Bluetooth, this speaker features an aux in port and USB allowing you to switch up your music sources and the USB port doubles as a phone charger. The three knobs on the top let you control volume, treble and bass. From the sound quality to knob tension, you'll notice the detail that went into the craftsmanship of the Crosley Octave Bluetooth speaker.
