The newly designed AKG legend, K 271 MK II combines the benefits of AKGʼs circumaural design for extreme comfort and a closed-back design for maximum isolation from ambient noise. Thanks to its XXL transducers, the K 271 MK II sounds clean, smooth and very rich.
The K 271 MK II is the perfect choice for any application where sonic bleed could cause problems such as broadcast work.
Another important feature of the K 271 MK II is the addition of a switch in the headband that mutes the audio just as soon as the headphones are taken off.
By the way, the K 271 MK II is also available as a headset with dynamic microphone (HSD 271) or condenser microphone (HSC 271).

| Headphone frequency response
The frequency response specifies the highest and lowest frequencies reproduced by the acoustic transducer of the headphones. |
|
5 - 30.000 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. |
