I have a Yamaha DTX900K electronic drums, so I was looking for quality headphones in which I wouldn't be able to hear the blunt impact of the mallet on the plastic-coated cymbals. These headphones did it to the letter! We don't even have to talk about the sound - long-term playing without any ear fatigue, balanced presentation with a slight absence of the lowest bass (probably a habit from Koss PortaPro) and high-quality isolation of external noise.
