Basically not bad headphones, the sound is mediocre and as always a little taste. In the price range, there are in my opinion better, especially as far as midrange and bass. The reason for my bad review: I purchased the headset due to the digital noise reduction, in conjunction with my Xperia Z3c. The headset is recognized by smartphone immediately, the noise reduction can be switched on and off. You can hear a difference in the background noise of the headphone. A noise reduction in the strict sense was not detectable by me. Neither traffic, PC fan noise, car engine nor any other noise was audible reduced. I have actively sought to identify the effect of uniform possible noise sources, without success. The only insulation is produced by the headphones itself, which goes deep into the ear and thus shields well. Since this but well advertised feature was the only reason to buy for me and it is fulfilled in any way, I can only advise against the purchase.
