Legendary sound. Personalized to you.              

Your music sounds best when the listening experience is tailored to you. That’s why Bose QuietComfort® Earbuds II are engineered with pioneering CustomTune sound calibration technology that optimizes the noise cancellation and sound performance to fit your ears. With personalized audio, you can enjoy the world’s best noise cancellation and deep, immersive sound with powerful bass wherever you’re listening to music.                   

The best noise cancellation of any earbud. Or headphone.    

QC Earbuds II represent a revolutionary advance in noise cancellation technology with the ability to cancel noise better than any noise-cancelling earbuds or over-ear headphones on the market. It starts with ensuring an optimal fit to your ears. The soft, silicone ear tips have an umbrella shape that creates a firm seal at the opening of your ear, reducing outside noises. Microphones then detect environmental noise and generate an opposing signal to cancel it, making your quiet sound quieter. CustomTune technology personalizes the noise cancellation to the shape of your ears to precisely soften sounds that are hardest to reduce, like voices.

You and your music in perfect sync.                         

QuietComfort® Earbuds II deliver lifelike, balanced sound with nuance, clarity, and depth, so you can get in the zone and feel seamlessly connected to your music. The wireless earbuds are engineered with high-performance drivers, amplifiers, and electronics that are custom-designed to fit a small package. CustomTune technology takes the sound to the next level by personalizing it to your ears, so your music sounds even more immersive and emotionally impactful.

Find your best fit with the Bose Fit Kit.     

To ensure your wireless earbuds feel comfortable and stay put no matter what you’re doing, QC Earbuds II come with a Bose Fit Kit. The convenient Fit Kit includes three pairs of ear tips and three pairs of stability bands designed to fit the unique shape of your ears. Both the ear tips and stability bands are made from soft silicone for all-day comfort and a secure fit. The ear tips rest gently but securely in your ears and spread contact evenly. The stability bands hug the contours of your ears with curved fins that grip your ears for a snug fit. And since no two ears are the same, even on the same person, swap different-sized ear tips and bands to find your best fit.            

You’re in control of your sound. 

With Bose QC Earbuds II, you decide how much of the world you want to hear. Quiet Mode offers maximum noise cancellation, so you can feel fully immersed in your music. Want to listen to music but still hear what’s going on around you? Aware Mode offers full transparency to hear your surroundings with striking clarity. This mode automatically applies ActiveSense technology to soften the loudest sounds, like a passing bus, to a more pleasant and balanced volume. Use the Bose Music app to disable ActiveSense or create custom noise cancellation modes.      

Crystal-clear, natural-sounding phone calls.               

Use Bose QC Earbuds II to enjoy clear and natural-sounding phone conversations. Two noise-rejecting microphones in each earbud focus on the sound of your voice and filter out ambient noise and wind. Digital signal processing technology further enhances the signal to ensure your conversation is clear. Calls play through both earbuds, or you can use either bud by itself. If auto-answer is on, and you’ve removed your earbuds, just place them in your ear to answer.       

Control your music with the simple touch interface.   

Use the simple touch interface on the wireless earbuds to control everything. This convenient interface frees your hands so you can stay focused on whatever you’re doing. With simple swipes and taps, play or pause music, change the volume, and switch tracks. You can even answer calls and change the noise cancellation level, all without ever touching your phone.              

They know when they’re in — and pause when they’re out. 

Need to pause your music to have a conversation? QC Earbuds II have sensors that know when they’ve been inserted or taken out. Remove an earbud and your music will automatically pause. No need to mess with your phone. Put the bud back in your ear to pick up where you left off.

Up to 6 hours of battery life. Even longer with charging case.

Stay absorbed in the music you love for up to 6 hours. When not in use, store your Bose QuietComfort® Earbuds II in the portable charging case — it’s small enough to fit in your pocket. If the battery gets low, voice prompts let you know. Out of power and don’t have enough time to fully charge? The quick-charge option provides up to 2 hours of battery life from a 20-minute charge. The case is magnetized to hold the buds in place, charges via USB-C®, and holds 3 additional 6-hour charges for a total of up to 24 hours of listening time.      

Sweat & weather-resistant earbuds (IPX4).              

Bose QC Earbuds II are a versatile musical companion that can go wherever you go. With an IPX4 environmental rating for sweat and water resistance, they can handle drips, sprays, and water splashes — and they’re built to withstand sweat. The acoustic mesh keeps out moisture and debris, so even if you get caught in the rain, the earbuds will keep working. 

Stay connected with advanced Bluetooth 5.3. 

To ensure your earbuds stay connected to your device, Bose QuietComfort® Earbuds II offer advanced Bluetooth® 5.3 capability. This newest generation of Bluetooth® technology offers a strong, continuous connection as long as you’re within 30 feet of the paired device. The earbuds keep track of the last seven paired devices to easily swap between them without reconnecting.

Control everything through the Bose Music app.                    

The Bose Music app guides you through setup. Use the app to access your preferences, including noise cancellation levels, Bluetooth® connections, shortcuts, and more. You can check the battery, customize your shortcut, and even adjust the sound profile of your music to your liking. Use Adjustable EQ to control the bass, mid-range, and treble levels to suit your tastes. Software upgrades and new features are also available through the app.

Great sound and noise canceling, mediocre case
The sound is really great on these earbuds, very well balanced. The noise canceling is also better than I expected from an earbud. The case, however, leaves something to be desired. My biggest complaint about the case is that the lid doesn't latch closed. I also have 2 sets of the Bose Soundsport earbuds. The case on those latches closed, so when I am travelling, the case doesn't pop open. With the QCII earbuds, since the case doesn't latch, I worry that it will just come open and I'll lose one of the earbuds. The other thing about the case is that the hinge seems a bit flimsy compared to the Soundsport case.

Surprisingly great
Purchased these headphones a couple of weeks ago. I use them for the motorcycle and I use them for music while working out.
When you put the headphones on and they are activated, all sound disappears, and when the music comes on, there's no static, distortion, wind, nothing. Pure great sound.
On the motorcycle I have a fairly loud exhaust. It makes my exhaust sound like a pebble in a tin can. When I put the music on, I don't even notice it. By far the best headphones I've ever used. They fit snug in the ear due to all of the different sizes. It's a great fit.
I have nothing negative to say. Very happy with the purchase.

Great Product!
I just purchased and I love them! I have the AAP's and they don't come close to what Bose has to offer. Now don't get me wrong, l love my APs. The sound and quality is just awesome! I'm happy I made this purchase!

Pathetic connectivity that trumps anything good
Pathetic Bluetooth connectivity. Either doesn't connect. When connect one earphone won't connect.

This makes anything good about it useless. I no longer recommend Bose to anyone

Excellent Choice
After reviewing several models on-line, I chose the Bose Quiet Comfort Earbuds II.
Very satisfied with the touch features, fidelity, and noise cancelling ability. For many noisy activities I perform with the likes of snow blowing, vacuuming, etc, I no longer have to wear headphones over the earbuds to cancel out noise.
