Rated 5 out of 5 by SzymonSebMalecki from Bose QC Ultras: A worthy upgrade from NC700s After four rewarding years with the Bose NC700s, I've stepped up to the Bose QuietComfort Ultras, and they've quickly become my go-to for navigating the hustle of London transport network. These headphones outperform in comfort and noise cancelling, a real boon on the noisy London Underground. I found the NC700s a cinch to keep in top shape with their replaceable cushions, and I’m hoping for a repeat with the Ultras over time. While I miss decking out my NC700s with a full shell skin from XtremeSkins UK—more for saving them from scratches than just for kicks—I’m eager to see what companies like Dbrand or XtremeSkins roll out for the Ultras. The QuietComfort Ultras bring the audio quality up a notch with Snapdragon Sound-certified Lossless Audio, which is a serious step up from the NC700s and I can confirm having owned them for years. The sound, particularly the bass, feels richer and fuller, even though they’re working with the same drivers as the NC700s. I believe that fact Bose already had a lot of experience with them and they proven to be very reliable alongsite the feedback from the online community has helped Bose make this my favourite sounding, comfortable to wear day to day over-head headphones I keep using, even thought I still remain carrying Quietcomfort IIs as a back-up or when I was to be a little bit discreet in Central London for my safety. Spatial Audio is more than just a fancy new trick—it’s genuinely refreshing when you re-listen to all your favourite tracks with these, and the ‘Aware Mode’ nails the balance between being lost in your music and staying alert to your surroundings which is now in pair with what Apple offers in their headphones. The newly added head detection feature which was absent on my Nc700s cleverly avoids any accidental pauses and it seems to work primarly on the right hand side cup, so when you need too you can still take one cup off your ear for a second without any disturption to your music and the overall music immersion. Moving from NC700s I was missing the assistant button and threw me off at first, however simplified control scheme grew on me over time and now it feels a bit like a testatment to physical buttons on Bose Quietcomfort headphones with a toutch of a modern design which I started to like very much. In a world where options like the Sony WH1000Xm5, Sennheiser Momentum 4, and even a bit more expensive and much heavier Apple AirPods Max these are definitely varying for attention to potential buyers. Quite a big disctinction from the competition is that they keep tge Bose USB Link compatibility which was a known feature on NC700s and being able to use the same USB dongle really sets QuietComfort Ultras apart from the convienence standpoint for me in this price range for seamless video calls which started to be an important part of our every day life ever since the pandemic. Having owned Bose USB Link since its release I was very much pleased that I continue using this addon every day at work. I use Bose USB link primarly for work and other online meetings. However when I pair these Creative W5x USB-C dongle oj my personal laptop for that sweet Aptx Adaptive sound listenining to maxed-out Lossless Hi-Fi music without a cable, it’s clear I these leave my NC700s in the dust and feel like a future. Considering that Ultras use the same drivers that my old NC700s had the sound has been tuned to perfection and you just need to experience your favourite track with APTx Adaptive codec and Snapdragon sound to really hear it. I'm nudging Bose to keep the updates rolling, like they did with the dual-bud feature for the QuietComfort Earbuds II. And hey, adding APTx support to Quietcomfort Earbuds IIs knowing that they have capability of having that would be a cherry on top—lots of chatter about that on the Bose subreddit after it was initiqlly believed that it would happen this year. As a happy Bose Quietcomfort II, owner I was a bit dissapppointed with the release of nearly identical Quietcomfort Ultras with same drivers at a very similar retail price to your existing more than capable earbuds. I can only hope that this wasn't just a marketing decision and I hope you can make this up Bose!! All in all, the QuietComfort Ultras are a solid bet for anyone eyeing the premium headphone market, ready to compete with the big names. Having them since day one in the UK, thanks to a prompt delivery just past October 10th, I’m set for the long haul. They're the kind of upgrade that makes a long-time Bose fan like me nod in approval and recommend without a second thought. I would be keeping these for years ahead as my go-to headphones for commuting, flying, work meetings and overall day to day use all things considered and will be assured that they will keep working and if anything I can always reach out to Bose’s amazing customer support directly to resolve any potential problems in pair with customer service Apple offers.

Rated 5 out of 5 by Dan from Amazing product. Excellent sound quality and comfort, the only thing that I don’t like them they are very susceptible to fingerprints.

## FAQs

### What is the difference between QuietComfort 45 Headphones, QuietComfort Ultra Headphones, and QuietComfort Headphones?

Bose QuietComfort Headphones are the successors to QuietComfort 45 Headphones. They deliver high-fidelity audio performance and world-class noise cancellation that allow you to hear more of your films and music – while travelling, at the office or at home. QuietComfort Ultra Headphones offer our most premium design and our most advanced technologies, for the best Bose listening experience in a headphone. With QuietComfort Ultra Headphones, you will enjoy our best headphone noise cancellation, audio quality personalised with CustomTune, and voice pickup, among other premium features.

### What is Bose Immersive Audio?

Immersive Audio allows you to hear audio as if it were coming from beyond your QuietComfort Ultra Headphones, thereby allowing for a more spacious, natural listening experience. Your music and other audio will have a wide sound stage in front and to the sides, just as if you were listening to a pair of stereo speakers and seated at the sweet spot between them.

### What is CustomTune technology and how does it work?

Bose CustomTune technology is a proprietary Bose technology that optimises the audio playback you hear based on the unique physical properties of your ear and ear canal. It works by playing a specially designed calibration tone as the welcome chime each time you power on the headphones while wearing them. It then measures how the shape of your ear uniquely modifies that sound. The headphones use that information to adjust their sound to your ears, creating a more balanced, authentic audio experience.

### What is TriPort acoustic headphone structure?

Proprietary TriPort acoustic headphone structure utilises external ports to vent the earcups and effectively enlarge the acoustic volume, without increasing the size of the earcup. The result is better audio and active noise reduction from a smaller, lighter, more comfortable headphone.

### How is total noise cancellation in Bose QuietComfort Ultra Headphones achieved?

Bose QuietComfort Ultra Headphones utilise both active and passive noise reduction technologies. They use a sophisticated proprietary electronics approach for active noise reduction, placing microphones both inside and outside the earcups. The electronics system senses the sound in almost any environment and then measures, compares and reacts – instant by instant – to produce an opposing cancellation signal. Meanwhile, passive noise reduction is achieved by the combination of earcup fit, design and clamping force of the headband.

### How do I control QuietComfort Ultra Headphones?

QuietComfort Ultra Headphones have three controls on the right earcup: a Bluetooth/power button at the bottom, a multi-function button in the back, and a capacitive volume strip along the edge. Additionally, the headphones are equipped with on-head/off-head detection, which is another way to control the product.

- The Bluetooth/power button is used to power the headphones on/off, put the headphones in pairing mode, cycle through paired devices, and more.
- The multi-function button supports audio playback (e.g. play/pause/skip), telephony (e.g. answer/decline calls), mode switching (e.g. Quiet, Aware, Immersion), and more.
- Swiping along the volume strip changes volume, and pressing and holding on it activates a user-configurable shortcut.
- Putting the headphones on and taking them off controls wake/sleep/auto-off and resume/pause. Auto-off can be customised in the Bose Music app.

### What are modes, and how do I use them?

Listening modes are collections of headphones settings that you can name and access with a single action. You can combine the following settings in a mode:

- Noise cancellation level
- Wind Block on/off
- ActiveSense on/off (applicable only in Aware mode)
- Immersive Audio setting

Three modes are provided by default:

- Quiet: noise cancellation set to maximum; all other settings off
- Aware: noise cancellation set to Aware; all other settings off
- Immersion: noise cancellation set to maximum; Immersive Audio set to Motion

With the Bose Music app, you can create your own custom modes as well as switch between modes.

### What is ActiveSense technology and how does it work?

ActiveSense listens for very loud outside sounds and selectively applies noise cancellation briefly during those sounds. This way, you can remain aware of your surroundings without having your music drowned out by interruptions like passing vehicles and loud appliance motor noises such as a coffee grinder or blender. ActiveSense can be enabled and disabled in the Aware mode setting.

### What is Wind Block?

Wind Block is a setting you can use when your environment is windy. Wind Block mutes the microphones on the outside of the earcups used for noise cancellation so that gusts of wind do not cause system responses that become noise disturbances in themselves. Note that the exterior microphones used for voice pickup are not muted, so if you’re on a call, the person on the other end will still hear the wind.

### Can I change equaliser settings on my Bose QuietComfort Ultra Headphones?

Bose QuietComfort Ultra Headphones also give you two options when it comes to audio EQ. Do nothing and the bass, midrange and treble of whatever you’re listening to will be adjusted automatically to make it sound great. Or choose Equaliser in the settings of the Bose Music app to change the audio levels yourself to however you like them best. Either way, you’ll enjoy immersive sound at any volume.

### Can QuietComfort Ultra Headphones take phone calls?

Yes. QuietComfort Ultra Headphones have an adaptive microphone system that allows you to use the headphones during calls when connected to any smartphone. In addition to traditional calls, the headphones will work with many apps that use Voice over Internet Protocol (VoIP), such as Teams, Zoom or FaceTime. The microphone system adapts to your environment to isolate your voice from competing background noises and wind so that you can confidently take a call, knowing you will be heard clearly and naturally. In addition, self-voice allows you to hear yourself naturally, as if you weren’t wearing headphones at all, so you can monitor the volume of your voice and minimise the effects of speaking while wearing headphones.

### How do I pair Bose QuietComfort Headphones with my mobile device?

First, make sure your headphones are turned on with the slider switch in the middle “On” position. Next, slide and hold the switch to the Bluetooth icon until the Bluetooth LED flashes blue or when the voice prompt indicates the headphones have entered into pairing mode. Please note, if this is your first time connecting the headphones, they will automatically turn on into pairing mode. Voice prompts will provide you with additional guidance. We recommend using the Bose Music app to complete the pairing process, however, Bluetooth settings on your device can be used to complete pairing.

### What is the range of QuietComfort Headphones?

Bose QuietComfort Ultra headphones have a range of up to 30 ft (9 metres) from the source device. This range may be reduced by physical obstructions, such as walls and doors, or by interference from other electronic devices. Pops or a cracking noise may be heard if there’s interference with the Bluetooth connection. If that happens, move away from wireless routers or microwaves and bring your headphones closer to the Bluetooth device.

### How do I charge QuietComfort Ultra Headphones?

The headphones can be charged using the USB-C cable supplied in the box and plugging into a USB port on a PC, laptop or wall charger. Allow up to 2 hours for the headphones to fully charge. The battery light indicator will show an amber light while the headphones are charging and turn green when fully charged. When you don’t have time for a full charge, the fast-charge feature provides up to 3 hours of play time from a quick, 15-minute charge.
