Poor maintenance, loose contact

This adapter does not seem to be made for 3.5 mm jack, but for 3.6mm. Thus hardly keep my 3.5 jack my headphones, and you only hear stereo when you plug something turns around until you find the right contact point found. And then it heist: Do not touch more, otherwise the sound is gone. For me as a DJ, it is important to have a reliable sound transmission, whether to speakers or headphones.
Since this adapter but even in a normal household as time goes on your nerves, and the sound quality is greatly reduced, I have to give this product 1 star (because 0 stars is not possible).
Because the price does not help much if sometimes garkein sound is transmitted.
