Review on Beyerdynamic DT 990 PRO 250 Ohm Studio Headphones (Ninja Black, Limited Edition) + 4-Channel Headphone Amplifier Bundle - Ultimate Audio Experience! by Kiril Nikolov ᠌

I use a Behringer umc204hd with a resistance of 250 ohm, and I swing the volume control to a level that allows me to work quietly. Its pros: An obvious improvement in sound quality when compared to the previous model, the AKG K240. They produce good detail, especially at the bottom, and when compared to monocles, the only area in which they are deficient is in the stereo panorama. They have replaced my primary monitors and a sub from PreSonus. Its cons: Non-detachable wire . This is a significant drawback because you are unable to customize the length of the wire, and as a result, the headphones' longevity is compromised. The plastic is of a rather low grade, but the design is fantastic in terms of both quality and ease. So I don't really endure too much pain.
