DT770 Specs:

• Transmission type: Wired
• Headphone design (operating principle): Closed
• Headphone impedance: Also known as nominal impedance. The impedance is the AC resistance of the coils of loudspeakers and headphones in ohms. Since impedance depends on the frequency, it is always specified at a frequency of one kilohertz. 250 ohms
• Headphone frequency response: The frequency response specifies the highest and lowest frequencies reproduced by the acoustic transducer of the headphones. 3 - 35,000 Hz
• Nominal sound pressure level: The (nominal) sound pressure level is the pressure in pascals (Pa) with which the air and the eardrum are caused to vibrate, better known as the volume. The sound pressure level is therefore a measure of the volume of a set of headphones under standardized conditions. However, it says nothing about whether the distortion is low and the sound is good at such a high volume. 96 dB
• Construction: Sound coupling to the ear. A differentiation is made between supraaural headphones, circumaural headphones and in-ear headphones. Circumaural (around the ear)
• Cable & plug: Stereo jack plug 3.5 mm (1/8") & 1/4" adapter (6.35 mm)
• Net weight without packaging: 290 g
