Review on 🎧 Beyerdynamic DT-990 Pro Acoustic Open Headphones (250 Ohms) with Knox Gear Compact 4-Channel Stereo Headphone Amplifier - Ultimate Bundle for Audiophiles by Stacy Mendoza

Would definitely recommend these two items, the amp is really great and not crappy like other amps. I like how it can be very loud like speakers. It was supposed to be loud and he nailed it. The overall quality of the cups is really good and soft. The only downside is the coil cable because it stretches so much but you kind of have to lug the cable around when the amp is on your desk but overall it's 5 stars. 1 Noise-cancelling is decent, but could do with a little better, as this allows people to talk outside the headset a bit, although not by much. Overall this is a really great headset and amp so definitely buy one.
