have unfortunately recognized immediately after purchase these headphones. The same I had in fact a few weeks ago bought for 2 at Woolworth ever. DC are the unpleasant Hall in sound, which greatly alienated all the songs. DC is that already during the first use by turning the plug in the jack until the correct position has to be found, so it does not creaks and both sides are heard. Just stupid that I thought on the product photo, it would be other headphones. Starting in the garbage, unfortunately.
