While this device may look like an old Fisher-Price Tape Player, what we have here is a bonafide music playback device designed for Google (probably as some sort of Tchotchke/giveaway) by Chord Electronics. The stereo is a variant of Chord’s Chordette Carry with inputs on the back for multiple devices as well as Bluetooth support.
Why this thing needs so many inputs is beyond me, but clearly this was supposed to ship at Christmas and since I didn’t notice anyone mentioning that they just got their “schweet Google stereo for being an affiliate marketeer” back in December, we can only assume that this gadget fell through.
Here’s the Chordette for context.
