Its a lead for connecting your 2 aux output/input together. Its sold at 1m long. Its sold for pennies. Its does the business perfectly.
If your looking for gold plated, ultra high quality sound from this product then you wouldnt be paying a few quid would you? If your looking to stretch 10 meters between appliances, you wouldnt buy this product would you?
Its sold as an in car aux input for an mp3 player, and it does this job effortlesly and a lot lot cheaper than any branded make that will do the exact same job. It gets 5 stars because I didnt have any pre conceptions that it would transform my cars speakers and that I would be able to appreciate the full spectrum of the music scale whilst doing 70 down the M6.
Buy this to put in your car, or even a home stereo amp. If your a professional musician/ producer/ D.J and have a £100 k studio, dont.
