Love to listen to books on my iPad or phone on long drives. Without bluetooth or MP3 hookup in my car, this is my solution! Plugs into the headphone jack on the phone/iPad. Cord is about 3 feet long from Aux plug (the plug that goes into the "cigarette lighter" of the car) to the headset jack, plenty of length that it might reach the backseat. (I'd rather it be too long than too short.) The tuner display is in the middle of the cord, so you can actually see the channel you are tuning to - unlike a previous one I had that melted in the heat of the car and fell apart, I couldn't read the display as it was at the aux plug location at a weird angle... I digress... I've used this many times in the last year. I store it in the glove compartment when not in use and it still works well. (I am a person that believes if you take care of your equipment, it will last longer, so I don't shove it in there. I wrap it neatly.) It also has a USB connector on the top of the Aux plug that was a surprise.
I totally recommend this product if you want to connect your media to your car and you don't drive a car that has that feature. It doesn't act as a "Handsfree connection" so don't buy this if that is what you need. It is really only to play your media through you car stereo (Ibooks, iPad, Music feature on my phone, etc...). It is simple, straightforward and easy to use. Durable enough if you treat it with care.
