The quality of this product is fine.
It is made entirely of plastic, but they make a very good impression and are thus more flexible and easier:
Pro:
-Günstig
-Good Sound and Bass (Two sets are: Equalizer for more bass)
-stable
-durable
-angenehm while wearing (as easily) and large ear pads, so that the ears are not pressing
Cons:
-Mirkrofon Not very good, but okey for 25.
-schlechte insulation from outside noise
-after 3 years excessive use go on the insulation broken tone controls (but is normal)
So for just under 25 can you do with this headset everything correctly !!!
