Three different silicone caps are included, as well as a small practical bag from Kunststoffgewirke with cord drawstring.
At the cable is still a small clip, with which you can cling the cable to the T-shirt etc.
The Sound I tested on a Samsung Galaxy S3 and a Sony Walkman MP3 player.
It now falls to the voluminous bass sound, the somewhat at the expense of a certain airiness and at the expense of heights.
Even the headphones apparently a fairly high resistance, since the maximum volume on this is not as high as usual.
Technically sound I personally would classify the the Sony mp3 players supplied headphones higher.
But the sound tastes differ so well known that one likes more bass, the other rather more heights.
Therefore, this description of the sound characteristics may hopefully provide an indication as to whether any of these sound could predict.
Overall, certainly very decent product!
