Notes

Know that the entire effect is mild and will seem subtle to those who have a great deal of experience with ANC headphones.
Know that the overall effect is mild and can seem subtle to those who have plenty of experience with ANC headphones. These work really well without any intrusive hiss; they're not so aggressive concerning cause the nausea/disorientation vacuum that occasionally includes other ANC technology and devices.


I tested these several times without sending any audio signal to the earphones. In my home office, the fitness center, or out on walks, the ANC did a nice job of lightly muting outside noises and making them less harsh, tuning them down to a lesser grade distraction. My music sounded much clearer and much more present to me at a lower volume than with other non-ANC earphones. This might save your hearing in the long term.

In windy outside environments, many earphones, especially the ones that do not sit so snugly in the ear, result in a great deal of unpleasant wind noise howling. With the NC9, it was greatly reduced ? due in part to the ANC, the ear tip seal, and the fit of the earphone body. I have been pleased with the ANC performance ? very good, without overfunctioning.

Much to my surprise, ANC mode significantly improves overall sound quality and enhances bass and sub-bass without reducing or muting mids and highs.

The other option is Transparency Mode, which enhances the human voice frequency band and improves the perception of the encompassing sound. As a result, you can hear what?s going on around you without taking right out the earphones.

How is this unique of simply pausing your music, you ask? The NC9 hears sounds around you, interprets and lightly amplifies them, and passes that to your ears. Incredible! This is an odd phenomenon if you?ve never experienced that ? you will determine what you prefer best, and when. Ultimately, the main point is to not have to remove your earphones to get a brief interaction or listen more fully to your surroundings (like crossing a street).

The NC9 has definite room for improvement with it?s voice microphone and voice call capabilities. Microphone performance seemed adequate for casual calls, though I would not advocate them for professional/business calls. My guess is that it may be a cost containment measure rather than a priority to include CVC technology. There is no ANC for the onboard microphones useful for voice calling.

tozo t-10 The onboard microphones for your voice are very sensitive. Other participants on calls could hear me, with intermittent complaints of ?chamber/tunnel? echo effects. To be heard well enough to make for a comparatively complaint-free call, I would have to be in a virtually silent environment for background noise never to be fed through to another(s) in a way that was more distracting for them than for me personally. With them outside or in busy environments?
