Directional characteristics

Omni-directional scanning (2)

Microphone directionality describes the microphone's sensitivity to sound from various directions.

Frequency from

20 Hz

Frequency is one of the most important parameters when choosing headphones. Generally, the higher frequency range of headphones, the better sound quality. The lower limit of the frequency range deals with bass reproduction. Frequency is measured in Hertz (Hz).

Frequency to

20,000 Hz

22 kHz

Frequency is one of the most important parameters when choosing headphones. Generally, the higher frequency range of headphones, the better sound quality. The upper limit of the frequency range deals with treble reproduction. Frequency is measured in Hertz (Hz).

Replaceable earcups (1)

Protection level

IP4x (2)

Protection against foreign bodies Ø 1mm and larger and wire contact.

IPx4 (2)

Sensitivity

108 dB/mW

Sensitivity is measured in decibels per milliwatt, or dB/mW, and describes the sound pressure level. Generally, the higher the sensitivity, the better the headphones are for sound reproduction. A higher value also indicates higher volume.

Equipment

Volume control (4)

Impedance

32 Ohm

An electrical parameter expressing resistance circuits in headphones in ohms. Headphones with lower impedance have a higher volume (important for portable media players), but greater distortion. Larger impedance equals lower volumes and lower distortion.
