The first participant is also the lightest pair by fair in this test. Furthermore it's also the smallest pair and the only pair of on-ear headphones. This design seems to be a bit contradictory with the purpose of the headphones, which is of course noise reduction. It would be much easier to achieve noise cancellation with an over-ear design compared to an on-ear design. The noise cancellation is powered by a built-in rechargeable battery, but there's no micro USB connection. There's a full-size USB to 3.5mm cable included in the box that you can use to charge your headphones through the audio output of your smartphone or other device. This isn't a very useful design in our opinion, since you can't charge the pair while listening to music. These cables are also not standard ones, so chances are small that you'll have a spare one lying around if you lose it by chance. Also, keep in mind that the N60NC cannot be connected wirelessly.
The sound quality of the AKG N60NC is very good. The balance between the various parts of the spectrum is excellent and the amount of detail provided is also good. The low tones aren't smothering the other tones which does happen on most other models in this test. This is a good thing for most music genres in our opinion, however you might find that the bass is lacking if you listen to hiphop, trance or other types of music that rely on low tones. The noise cancellation feature is enabled by flipping a switch on the left earcup. There aren't multiple levels of noise reduction, you only get on or off. We aren't extremely impressed by the this aspect of the N60NC. It definitely cancels out some noise, but we can definitely still pick up things around us.
