Bought the cable as the aux point in the car is in the glove box and car doesn't Bluetooth audio stream amd we wanted to play our offline spotify playlists.
Cable is absolutely perfect as the glove box closes perfectly and I am able to use cable to connect my phone and use spotify through the aux in feed. Cable seems to be durable and of good quality, however only time will tell how long it lasts.
Sound quality is fine, however is clearly dependent upon the quality of the music stream from the portable device and the quality of the car stereo, as we noticed that different songs via spotify played with different crispness and quality of sound, if the encoding was good then sound quality was good, if not then it meant turning up the volume, but nothing to put us of from using the cable and clearly not entirely down to the cable quality.
Seems like a sensible choice for those cars where the manufacturer has decided to put aux in glove box or the centre arm rest and there is no Bluetooth audio stream, however you obviously cannot control the songs/playlists through the aux interface (at least that is the case with my car and htc wildfire using spotify)
