The cable is a little long for my use. The potentiometer works but unreliable: sometimes the sound is louder in one ear than the other, and sometimes while the sound should be cut, in fact it comes at the height in one ear ... But this is the only cable with volume control with an affordable price.
Big negative after having already tested two of the same model: super unreliable and fragile. The first had to take one month, the second not even two weeks ... Avoid so shame!
