This iSimple BlueJax ISBT32 adapter connects to most standard 3.5mm auxiliary inputs, so you can wirelessly stream music from a compatible Bluetooth-enabled device. The built-in rechargeable battery offers more than 8 hours of use for extended listening
I bought this to use at work when I'm on the road and use it in my own car as well. Super easy to use! I almost always plug it in and charge it over night and it always works great for at solid 6+ hrs. 3 things to keep in mind, 1. I need to be extra careful and put in my pocket if I take it out of the car. Due to it's shape, I find it too easy to drop. (If it was sold with or made with a rubber anti-shock ring I'd be super impressed) 2. If I'm in and out running errands, I sometimes lose the bluetooth connection and am forced to disconnect and reconnect the bluetooth connection on my iPhone 6 and power off and power on this device. Happens occasionally - not a lot, but sometimes. 3. I have an Alpine head unit w/ a 250W amp. When I used an aux line to connect my phone to the Alpine head unit my max volume setting would be "19" (max is 31 or 32) With this device I most often use a volume setting of 23-26 to get the equivalent of the "19" with the aux line. When I use it in my work vehicle ('15 Tahoe stock stereo) I turn the volume between 3/4 and max and sound quality is great. I have used it in a '13 Tahoe w/ stock stereo and it is VERY hard to hear anything.
