Right off the bat, I can tell you that these earbuds fit and feel fantastic. I am a bit of a tough customer when it comes to earbuds since I have small ears, and I typically prefer over-ear headphones or earbuds without a silicone tip. The new QuietComfort earbuds, however, have a design that feels far lighter and more comfortable than they look.

The buds appear somewhat chunky, but when they’re in-ear, they feel incredibly light and minimal. The angled, oval-shaped ear tips differentiate themselves from the wide, completely round tips that a lot of other earbuds have, resulting in a secure but comfortable fit.
That being said, there seems to be one single way that these earbuds go into the ear: there’s a single optimal angle where they “click” into place, and if you don’t get it right, they don’t feel secure. I took the QuietComfort buds to the gym with me for a week, and a rushed placement one day resulted in not one, but both earbuds falling out of my ears onto the floor.
Needless to say, I now make sure to take the time to put them in correctly before hitting the floor.

So let’s talk about the sound. As you’d expect from Bose, the audio quality on these earbuds is rich and booming. The bass is fat and all-encompassing, the mids are distinct, and the highs allow for a textured, dynamic soundstage. There is a good deal of separation between sound elements, and the sound quality is virtually indistinguishable whether the active noise-cancellation (ANC) is on or not.
The approach with these earbuds seems to be to provide an aggressive, bass-forward audio profile that pairs well with noise-cancellation to be good for commuting, exercising, or in otherwise loud environments.
The sound quality goes hand-in-hand with the redesigned companion app, which provides a fair amount of customization. You get a few pre-set EQ settings, including a bass booster and reducer, and a custom five-band EQ window where you can adjust as you see fit. The bass booster setting sounds pretty good on most content, but the low-end is so fat that it can end up sounding a little muddy on some tracks.
I found the custom EQ settings to provide the best sound profile, bringing up the mids and highs to compete with the hefty bass these earbuds are capable of. On my custom setting, the buzzing, bone-shattering low end in Aïsha Devi’s “The Seventh Element” pairs seamlessly with lighter tones, giving life to the airy flute that rides atop the abyss.
Another track with intense bass, Sega Bodega’s “Adulter8” sounds expansive and textured in my custom EQ – despite the crushing bass at high volumes – whereas in the custom “Bass booster” setting it sounded a little too thick and soupy, with the lower end bleeding into other sound elements.
