THE SOLUTION FOR THE POOR IN HI-END SETTINGS... after we got disappointed with the BeyerDynamic DT 770 Pro due to their many positive reviews (terrible reviews, terrible sound, and a price that in my opinion shouldn't be more than 30 euros), I was looking for something more valuable in terms of sound and I came across these... well... 89 euros and not the price of the previous ones I mentioned... German at first, these are Chinese... well, the Chinese have surpassed the Germans... firstly, in terms of sound quality... secondly, in terms of packaging and finishing... they fit perfectly in the ear, lightweight, and now let's talk about the sound... they deliver what they promise... equivalent to the more expensive pioneer hdjs... in cheap hi-end studio solutions, this is a powerful product... I am very frustrated that I believed in evaluations that probably have no idea about hi-end sound... of course, if you want to experience hi-end settings, you have to spend 1000 euros or more, but for a cheap and reliable sound solution, in my opinion, and of course, evaluating the product in terms of sound quality and value for money, I would give them over 90%... they are simply amazing... of course, due to their high impedance, you will need an amplifier... they work with tablets and mobile phones, but not loudly (you need amplification)... now, I didn't try them with computer sound cards because I directly connect them to amplifiers, a Sony and pioneer sound... they play all frequencies perfectly, you will be impressed... the ones I bought for 80 euros are the most expensive ones from the company, their flagship... I am just amazed compared to the previous ones I mentioned... I say it again, hi-end studio quality, they are simply outstanding
