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 Riko Long ᠌

Great ears for home or studio. Take high-end versions, on good amplifiers they sound more interesting, as it seemed to me, compared to 80 ohm ones. Good detailing of high frequencies, I heard in familiar tracks what I hadn’t heard before) The bass is rich and deep enough, but it doesn’t bother even on bass tracks, it’s in moderation. At first there was a lot of "clicking" on high, but after warming up the sound became more coherent and natural.
