3 days of life ...

The exterior finish yet inspires confidence, contacts seem well made too. The sound then became very weak on the right channel and after 3 days the audio signal crackles non-stop .... I said that the cable remained on my computer, so no mobile use with a torsional stress etc. ...

The only good-adapter cable that I was the one provided by Sennheiser HD headphones with my 650, I unfortunately lost; I thought I had found a replacement ... but no, definitely not; a product of such a crummy bill should not even sell for 10 cents
