Sound quality:

We found the NANOBUDS ANC (MZX5300) delivers sound quality that falls in the very good range - it reproduces music and voice very well although it does have some noticeable sonic quirks and excellent active noise reduction. With the noise cancelling mode engaged the bass (as in bass drums, bass guitars, stand-up bass, etc.) has good impact and goes deep but is somewhat prominent and boomy, and somewhat crowds the midrange. The midrange (voices, guitars, horns, etc.) is fairly even but is a bit grainy and congested (think sonic traffic jam), and a touch hazy. The treble (cymbals, the upper range of violins, etc.) is a bit prominent, somewhat sizzly (sounds that should have a delicate shimmer have a sound reminiscent of bacon frying) and a bit smeared; although it is extended, at times the upper treble (cymbals, the upper range of violins, etc.) can sound a bit muted. The sound also has a good sense of liveliness and is somewhat open--sound-wise it almost seems like you don't have anything plugging up your ears and does a decent job of recovering room ambience in the upper midrange and treble, but is so-so in the lower midrange and bass. Mixed character - warm bass with neutral midrange and cool treble. The overall sound can be summarized as somewhat bassy and a bit grainy and sizzly. Noise Canceling: Excellent noise reduction across the entire frequency range with the low frequencies reduced the most. A very faint rushing sound can be heard in quiet environments when there is no audio program to drown it out.

Comfort and Fit:
As typical of in-ear models they produce a sense of pressure in the ear canal opening that might be uncomfortable for some. Users with small ear bowls might find that the earphone body feels bulky in their ear bowl and feels like they may lever out of place, but they will stay in place during casual use and are very stable even during vigorous head movement. Users with medium to larger sized ear bowls will probably find that this model stays in place with no problems for casual use and that they are very stable even during vigorous head movement. Incidental contact with the touch controls can cause unintentional volume level changes, playing, pausing, track skipping, or ambient sound monitoring.
