They need a few hours of break-in to open up to all kinds of sounds. Sound insulation is good and fits well with any audio playback device.
The frequency response ranges from 18 to 22.500 Hz and from impedance to 55 Ohm (as well imprinted also on the headphones pads). Headphone sensitivity: 114 dB.

The mid-high tones come out very well.
