I bought it because it was the only cable that clearly stated in its description that it is exactly what I needed, a quadruple cable with connectors on both ends to transmit audio + microphone from headphones that have their own microphone. However, within 1 month of use, the contact on one side of the cable has already deteriorated, and when the cable is moved, the sound is lost from one earphone. This shows that it is an extremely poor quality cable, which has no hope of lasting more than a few months of use...
