The angle adapter, which is sold here, making an unstable impression as any other of its kind. The gold-plated tip is nice to look at, but brings zero benefits.
This adapter is not a perfect finish on the thinner 3.5mm-end, so that excess plastic protrudes. The excess material first had to be filed off.
The biggest shortcoming is that the adapter does not come with cables longer cope. With a 1.8m cable it works, with a 10m cable is no longer. This is surprising, given the identical adapter worked by electric local dealer three years.
