Review on Amazon Basics 8 Foot Stereo Audio Cable: 3.5mm Male to Male – High-Quality 2.4 Meter Sound Cable by Michael Cox

Reviews of this cable don't really warrant it, RevainBasics already gave me a solid range of cables. This cable was exactly what you are buying, a 3.5mm cable NOT intended to be used for purposes where the sound passes through more than one source. For my home setup I use two audio devices which normally do NOT cause "hum" audio feedback in my headphones but with this cable it does. You have to buy a ground to make it go away or the Audio-I /O toggle to isolate and repair it. Only need this cable for speakers, car radio etc. 100% 100% guaranteed but if it is more complicated, buy a more expensive quality cable and save yourself the hassle.
