Every ear is different, so why are most earbuds the same? Bose QuietComfort® Earbuds II change all of that, giving you the power to personalize your earbuds. These next generation wireless earbuds are engineered with pioneering CustomTune™ sound calibration technology that personalizes audio to your ears. In addition, each earbud comes with 9 sizing options, ensuring the best fit for you.

Here's how Bose's new QC Earbuds II get personal.

CustomTune technology

One of the primary upgrades of the QuietComfort Earbuds II is Bose’s CustomTune technology, which calibrates sound in a new way. When the earbuds are placed in your ear, a chime is played. The microphone inside the earbud measures the sound in your ear canal and adjusts it to create a perfectly balanced sound for your own eardrums. CustomTune technology also compensates for the differences in individual ears, as the left and right are not identical in shape, size, and condition. The result is truly personalized sound balance.


CustomTune technology doesn’t just benefit what you hear, it also helps with what you don’t by personalizing the noise cancellation to the shape of your ears. This will precisely soften sounds that are hardest to reduce, like voices.

Fit Kit

Another new tool to make your comfortable earbuds even more personal is the “fit kit” that comes with each new pair of QC Earbuds II. The Bose QuietComfort Earbuds II Fit Kit includes three pairs of soft silicone eartips, allowing you to choose the pair that is most comfortable for you, and three pairs of stability bands, which wrap around the external part of the earbuds to further tune them to the shape of your ears. Stability bands are made of soft silicone for all-day comfort and a secure fit. The eartips rest gently but securely in your ears and spread contact evenly. The stability bands hug the contours of your ears for a snug fit. And since no two ears are the same, even on the same person, swap different-sized eartips and bands to find your best fit.

World’s best noise cancellation

Noise cancellation is often a matter of personal preference. Bose technology sets itself apart by allowing users to adjust levels to what suits them and their situation best, while others only offer two settings — on or off. If you’re working in a bustling coffee shop, Quiet Mode offers maximum noise cancellation, blocking out customer commotion and sounds like crashing dishes around you. If you’re walking down a busy city street, Aware Mode automatically applies ActiveSense™ technology to soften loud sounds, such as a passing bus, to a more balanced volume, keeping you cognizant of what’s happening around you. If you want a noise cancellation level that’s somewhere in between, you can use the Bose Music app to create up to 10 custom noise cancellation setting, enabling you to home in on the audio you want to hear and block out anything you don’t.

Bose Music app

Noise cancellation is just one of the many options the Bose Music app offers to personalize and fine-tune your listening experience. You can also use the app to manage Bluetooth connections, connect to streaming services, adjust in-ear detection, set phone call preferences, check the battery level, access your voice assistant, and create “favourite” settings that you can quickly tap on the QC Earbuds IIs’ touch interface. Another important aspect of sound personalization is the equalizer, which lets you set bass, mid-range, and treble levels to suit your ears, listening situation, and audio quality.

Personalized earbuds for a personalized experience

When it comes to the music we listen to and love, the closer we get to it, the better our energy, spirits, and productivity become. This makes personalized earbuds quite valuable, and each new tool at your disposal in the Bose QuietComfort Earbuds II offers greater personalization than ever. Now you can customize earbuds in ways you’d only dreamed about and create a sleek musical companion that helps you be more you.
