This wireless audio adapter makes anything Bluetooth compatible. Just plug your audio signal in and pair it with your speakers or headphones! It has a port for a regular “aux cable” sized plug (1/8” input). So you can plug in your tape deck, your turntables, your television, whatever — then play that sound with a Bluetooth speaker or headphone set. Also, if you have a newer TV, this thing has a digital optical cable input as well (like most Soundbars use). I’ll give you a DAC cable with it, it makes the sound quality clearer / better / a little bit louder. I barely used this thing, only once or twice really. It cost me way more when I got it off Amazon, I think around 30$! But hey, I’ve really got no use for it now. I used to have two UEBoom-2 speakz. I would use the phone app to stereo-pair them, then play my TV through them via Bluetooth. — Sounded super great! But now I’ve sold them both & just have a normal, boring, wired sound-system for everything. I’ve really got no use for this thing, so it’s going cheap. UPDATE **NOW EVEN CHEAPER: $5.00 only! Wow! 5$ for the converter, a DAC cable & a USB chord to power it. Five bucks people. Offers & Trades welcomed as well.
