It is by putting it on your ears you will see where AKG has focused on the essential, the sound quality. The features are impressive on paper: 53 mm transducer composite with rear vent Sensitivity 110 dB SPL / V at 36 ohms impedance only. To the ear, the feeling is faithful to the promises: a pure, without addition, as known to the brand.
And the distribution chain does not lie: this is not the mainstream branch of the brand which markets, but the pro division, which serves the music studios.
Only limit, and this is the consequence of the above: no need to buy it if you do not have an audio system at the same level, otherwise it is money thrown out the window. As good as the headphones if sound sent to it is rotten ... you can guess the rest. Make the first test with an MP3 and a CD then: the loss of quality due to compression means right away with this headset. A sign that does not deceive.
Compared to its competitors such as the Sennheiser HD800 or Grado GS1000i, the price is a bit higher (1300 against 1150 and 1000), but is justified by the quality of sound, a step above.
