They have the signature crisp highs like the KZ I know. When talking on the phone, it picks up all sorts of background noise that makes it impossible for people on the line to hear me, especially (again), if I am outside. No tienen ni la escena ni la profundidad que tienen los MSR, pero tampoco es que esté tan lejos, ya que como explicaba arriba, tienen mucha más que los M50x. Thats the trade-off and not the shoes fault. My only problem is with the tread/bottoms of the boots. This company may inconvenience you terribly but you will get a very high quality unit in the end, despite the inconvenience but maybe Advenor has solved their issues with sending out units without missing parts. Other than this modest problem, the Cougar Bunker S Headset Stand is a good purchase that I?m very happy I made. These were easy to clean and he could wear them all day in any weather summer threw at us. This is a very stylish wall bike mount and it is super sturdy. I used to be able to touch it and not even look at it and discern the plus volume from the pause and the low volume buttons.
