I use these headphones for some time and I tried a lot of other models in the past. For its price (45 euros) I must say it is a good product, but not particulirement suited for professional use. It is relatively comfortable but not for long hours of cost. The soundproofing is not great, but hey, That a better headphone open type. Regarding the sound, it is quite impressive to beginners, a little tired at the time, but facing the COMPTITE the Beyer are good. Submitted highs are, too serious, but not so deep. Srieux nothing wrong with that price, but I prfre the medium a little more and more Submitted civiliss in the spectrum above medium. You get what you pay, a headphone enjoyable and more analytical than most of the COMPTITE, with the exception of a few Sennheiser may be. A good buy for the budget.
