Design and features:This is a Bluetooth wireless noise-canceling portable ear-insert model. Its ear plug-like design and electronic noise canceling feature reduce both outside noise and sound leaking out into your environment.
Additional features:Has integrated volume control, microphone, and call connect/disconnect control. Either earphone can be used alone for one ear monitoring of Bluetooth streamed audio and telephone communications. Free Bose Music app for Apple and Android mobile devices adds additional features.
Sound quality:We found the QuietComfort Ultra Earbuds (2nd Gen) 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. The
bass (as in bass drums, bass guitars, stand-up bass, etc.) goes deep, but is prominent and boomy. The
midrange (voices, guitars, horns, etc.) is a touch thin and is a bit hazy, grainy and congested (think sonic traffic jam) , and is somewhat overwhelmed by the bass. The
treble (cymbals, the upper range of violins, etc.) is extended, but is a bit prominent, sizzly (sounds that should have a delicate shimmer have a sound reminiscent of bacon frying) and smeared. 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 good job of recovering room ambience. Mixed character - warm bass with neutral midrange and cool treble. The overall sound can best be summarized as bassy and a bit sizzly. A faint rushing noise is audible when music is not present to mask it.
Noise Canceling: Excellent noise reduction across the entire frequency range with the low frequencies reduced the most. Orientation does not changes the noise reduction characteristic. A rushing noise is audible when music is not present to mask it.
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.
Small
Users with small ear bowls might find that the earphone body feels bulky in their ear bowl and that they stick out too far and feel like they may lever out of place and are mostly held in place by the section of the earphone that is inserted in the ear canal and ear bowl, but that they will stay in place during casual use and are very stable even with vigorous head movement.
Medium
Users with medium sized ear bowls will probably find that with or without the ear bowl supports this model stays in place with no problems for casual use and that they are very stable even during vigorous head movement.
Large
Users with large sized ear bowls will probably find that with the ear bowl supports this model stays in place with no problems for casual use and that they are very stable even during vigorous head movement.
Hitting the stem that hangs out of the ear can knock an earphone loose and cause it to fall out of the ear.
