The cable is about 27cm long (from plug end to connector end).
I find this length optimally. It extends to the branch should get good, but does not lead to Kabelwirrwar.
The connectors are high quality. The housings are made of greyish aluminum, plated the plug contacts themselves.
The 3.5 mm connector is located almost perfectly in the audio-out jack on the S5.
Here the slender design is particularly noticeable (in a good way).
Even with the two Logitech headphones, which are usually used with us, whose 3.5mm jack fit also very well in the two female 3.5mm Receptacles the cable.
There is nothing negative to sound, on both audio-out signal is as usual clear from S5.
I highly recommend this cable given the quality so completely recommend.
Only the price is maybe one or two euros too high.
But this is certainly my subjective opinion.
I hope this review could assist you in your buying decision
