Very high quality headphone extension,

Top cable, simply because of the built-in 6.3 mm jack for the receiver!. No annoying adapters are no longer necessary. In the 3.5 mm jack fits on the other side my headset perfectly and without wobbling even minimally !.
The cable is very solid and processed with metal plugs and looks quality. Here you have the best example that even at such a premium cable (Series 4) no gilding is necessary and the sound is brutally clear and precise (even with 6m length).
So will I need in this processing and quality no gilded cord, even if it is cheaper.
For me this Adam Hall Cable gets a very strong buy recommendation, even for very high demands. The long search for the optimal KH Verängerung cable was truly worth it for me! ,
