Sony Noise Cancelling Headphone NC31EM Black for Sony Xperia Z2 (bulk packaging)

these are the sony noise cancelling earbuds for the Xperia z2 hi Dan fagre diary one of the aspects of the Sony Xperia z2 that I love is the implementation of noise cancellation these are actually the noise cancelling earbuds that go with the Xperia line both the phone and the tablet what you might notice about these is that they don't have any sort of a a box a noise cancellation box that holds the electronics for noise cancellation and the battery and the reason for that is that these earbuds which have a small hole right there so that the ambient sound can actually come through them these earbuds actually rely upon the phone and the tablet's noise cancellation to do the heavy lifting so the electronics for the noise cancellation is in the phone of the tablet and it relies upon the battery of the phone of the tablet not the earbuds the result are earbuds that look like standard earbud
