Were initially shocked because the tablet very Tinny Sounds but it's a headset with microphones so.
Therefore, the plug 4-pole is whereas a normal headset is 3-pin. Supports on my phone headsets which sounds good when you press the little button reacts phone with Play or Pause So everything was wonderful.
On mobile, the sound quality is fine. Too bad that it is not quite as good Klappt on Tablet our daughter but who you unplug not reinsteckt to stop it is also because with a good sound.
So quality are good happy happy again :-)
