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.
