I received this product for free test. This headset does not work on all devices: I tried it on three computers: it worked only on one and on my phone. He is a jack compatibility problem rather strange that I had never seen before.
The design and color are successful. The sound is just ok, not great, but it does the job for the price, you can not ask for more. However, it insulates external sounds. The headset setting is not suitable for small heads.
