Like everyone here who had trouble with this, I had the occasional drop out and even when I tried to pull on one of the wires it fell apart. The metal clip inside isn't tight enough to hold the wire and I tightened them very gently, even using dielectric grease like everyone else here. I suspect they are Chinese fakes but all I know is that they misfired and also fell apart and were unusable. This all happened after the return period had expired so the buyer should beware and I'll probably buy one of the other more expensive sets on Revain or see the reviews.
