Bose Noise Cancelling Headphones 700 vs Bose QuietComfort 45 Specs: Top Full Guide 2023

Bose Noise Cancelling Headphones 700 vs Bose QuietComfort 45 Specs

There is no argument that Bose makes the best noise-cancelling headphones in the market right now. However, you might find it hard to decide which Bose noise-cancelling headphone to choose. In today’s article, we discuss the difference between the Bose noise cancelling headphones 700 vs Bose QuietComfort 45 specs.

What’s The Difference?

What’s The Difference

You really can’t go wrong with any of these models when it comes to noise-cancelling because they both provide excellent experiences; however, the QC 45 model performs better than the 700 model thanks to upgraded noise-cancelling technology.

The two noise-cancelling modes that come with the QC 45 are simpler and more user-friendly in terms of navigation. The difference between the two models in terms of sound quality is tiny but distinct, with the 700 model just just beating out the QC 45.

Both devices have a sleek, contemporary style, but the QC 45s’ battery life is substantially greater. Both versions have good microphone quality, making them appropriate for both professional and casual calls.

Audio Quality

Since Bose has been in the noise-cancelling business for years, you can count on it to provide exceptional sound-per-pound performance, and, more importantly, noise cancellation that doesn’t degrade the caliber or neutrality of your music.

The 700 has a natural soundstage, and the companion app’s addition of a programmable EQ with presets enables users to fine-tune audio to suit their ears.

When it comes to frequency range, lows are given preference, but mids and highs aren’t ignored either. Brass and string instruments can be clearly heard, and vocals are reproduced clearly.

The QuietComfort 45 is designed for bass enthusiasts, and it has a warm, full soundstage that produces deep, oomph-filled lows. If you believe that midpoints and highpoints are underappreciated, think again.

You can hear music in its whole, without any distortion, thanks to Bose’s combination of unique TriPort acoustic construction and a volume-optimized Active EQ, which produces a wider frequency response.

Not all tracks have a smooth sound, especially symphonic recordings, which the QuietComfort 45 sometimes seems to struggle with. It’s unfortunate that there isn’t a means to customize sounds, but we’re hoping Bose will include EQ capability in a later update.


bose noise cancelling Design

The Noise Cancelling Headphones 700 from Bose have a modern design and an adjustable, all-metal headband. There is no disputing that these headphones are aesthetically pleasing and stand out among other Bluetooth models.

The Bose Noise Cancelling Headphones 700 have just three buttons, with playback controls switching to a touch-sensitive gesture pad on the right ear cup.

There are no hinges for folding, but the ear cups can rotate 90 degrees to rest around the neck. To protect the headphones from scuffs, use the hardshell case that comes with them.

The QuietComfort 45, on the other hand, is stuck in the past with an outmoded design that has been around for more than a decade. However, this design is undoubtedly more comfortable due to its uniform weight distribution and lack of discomfort or tiredness during extended listening sessions.

The Bose Noise Cancelling Headphones 700 have stiffer ear cushions than the Bose QC 45, which leads to heat accumulation and perspiring ears. The rubberized headband of the NCH 700, which is another drawback of the slimmer headset, pulls on hair.


Both pairs of headphones offer excellent comfort, but we believe the QuietComfort 45 to be more comfortable to use.

When holding both models side by side, you’ll notice that it is lighter in weight, and the padding on the skull and ears is pleasant. Although you’ll need to carefully adjust the extenders to ensure the best fit, the flexible frame provides more wiggle room when used in tight circumstances.

It’s cozy inside the 700. Because of the special track system that enables them to effortlessly slide up and down, adjusting the extenders is a very easy process.

Additionally, the headband performs a good job of molding to the skull for a snug fit. Simply deal with the uncomfortable, exhausting clamp force on the ears after two hours of use.

Battery Life

Battery life is one area where the QC 45 beats the Bose Noise Cancelling Headphones 700; the QC 45 has a 24-hour battery life rating as opposed to the Noise Cancelling Headphones 700’s 20-hour rating.

However, a variety of factors might affect the battery life of headphones. Additionally, both headphones charge via USB-C, which is a considerable improvement over the tiny USB port of earlier Bose headsets. Both headsets support quick charging.

The Bose NCH 700 provides 120 minutes of playing after a 15-minute charge, while the Bose QC 45 provides 180 minutes.

Noise Canceling Ability

The Bose 700 has eight microphones—six for noise cancellation and two for voice pickup—and an intensity level that can be adjusted on a scale from zero to ten. You can scroll through the levels in the Bose Music App to find the level that works best for you.

Both models have active noise-cancelling technology capable of blocking out the outside world.

Even though the QuietComfort 45 only has “only” six microphones with four beamforming and only two preset modes of noise cancellation (Quiet and Aware, which let you can hear what is going on around you when necessary), the noise-cancellation is nevertheless effective.

We put the QC 45 to the test, and while it is obvious that the Bose 700 offer a smarter and more customizable noise-cancelling experience, it isn’t always superior if you just want to block out as much noise as you can at the office.

The Bose 700 can’t quite block out as much noise as the QC 45 when it is in “Quiet” mode, especially through the midrange, even at 10 (the maximum level of noise-cancellation).

Two pairs of headphones that comfortably sit at the top of the noise-cancelling pile are in a very close race, but the Bose QC 45 comes out on top.

That being stated, you should consider the Bose 700 if you prefer the choice of having a less intense noise-cancellation intensity for particular circumstances or a more personalized, robustly featured experience generally.


Bose noise cancelling control

The 700 takes first place in this round because it has on-ear recognition, tactile buttons, and responsive touch controls. Playback and call management are so simple to use because of the touch panel (only on the right earcup) tap and swipe movements.

The buttons are obvious, and pressing them results in a satisfying click that reassures users that their directions have been carried out.

When the headphones are taken from the head, content is immediately paused thanks to effective motion detection. Digital help is the only thing that is more dependable than the controls.

Bixby, Alexa, Siri, and Google Assistant all function well. You may even activate Amazon’s AI bot hands-free by using the wake-word feature of Alexa.

Bose assigned the same button arrangement and functionalities to the QuietComfort 45’s controls as they did for the previous model. The left ear cup’s Action Button is now only used to switch between ANC modes; the digital assistant can no longer be set to it. This is the only alteration.

Each set of headphones produces good tactility and responds quickly to directions, although the QuietComfort 45 suffers from the absence of touch controls and motion sensing.

Call Quality

The best headphones with a mic for voice and video chats are the Bose 700. It uses six of its eight microphones to achieve the highest level of noise cancellation while maintaining remarkable clarity.

Strong wind resistance reduces the impact of whisking while walking near moving vehicles or in windy circumstances. Additionally, particularly in noisy areas, the Self Voice option is crucial for completely hearing talks. On Android and iOS smartphones, it continues to be our preferred headset for phone and FaceTime calls.

For voice and video chats, we also like the QuietComfort 45, despite the fact that it is a step back from its predecessors. The call quality suffers when the wind is present, but you’ll still receive loud, clear results and some great noise reduction.

No matter whatever model you choose, expect to spend a few hundred dollars on a Bose gadget. The QuietComfort 45, which surprisingly had a lower MSRP than its predecessors at $329, is the more affordable choice. Black and Smoke White are the two colors that are offered.

The 700 was initially released with a $399 price tag, however it is now offered for $379. It is available in Black, Luxe Silver, Soapstone, and a limited-edition Black/Copper model with a charging case included ($449.95).

The 700 has frequently been on sale, sometimes going for as little as $229.95, and it is sure to be included in this year’s Black Friday specials.

Don’t expect a reduction any time soon with the QuietComfort 45 just entering the market. In any case, while taking into account overall performance, the price points for these two models are justified.

Who is the Winner? Bose Noise Canceling Headphones 700 vs QuietComfort 45

Who is the Winner Bose Noise Canceling Headphones 700 vs QuietComfort 45

The QuietComfort 45 is a great improvement over previous models in the line, but it can’t compete with the powerful 700, which is Bose’s top model.

These headphones are beautiful due to their adaptable sound, excellent call quality, and sleek appearance.

The 700, however, is in a league of its own thanks to the best-in-class ANC, which cancels outside noise at a level and in a manner that no other model, not even the most recent noise-cancelling model from Bose, can match.

When considering the QuietComfort 45, the feat of being in second place shouldn’t be overlooked. Any significant improvements to these cans’ performance are superficial and sufficient to make them worthwhile purchases, particularly for QuietComfort 35 II enthusiasts.

FAQs about Bose Noise Cancelling Headphones 700 vs Bose QuietComfort 45 Specs

FAQs about Bose Noise Cancelling Headphones 700 vs Bose QuietComfort 45 Specs

What is noise cancellation?

A system intended to cancel out background noise for a better listening experience is generally referred to as noise cancellation, which is more correctly known as Active Noise Cancellation (ANC).

Background noise is decreased using microphones and speakers. The ANC chipset inverts and cancels outside sound waves inside the headphones.

Do Bose QC 45 have a mic?

Yes, these headphones isolate and concentrate on your speech using four external microphones, and a noise-rejecting algorithm blocks out background noise to ensure clear conversations even in windy, chaotic environments.

Does Bose QC45 leak sound?

The Bose QuietComfort 45’s leakage performance is adequate. Compared to in-ears and earbuds, its leaking is primarily centered in the mid-to-treble region, making the sound a little fuller. People around can hear some of your audio if you choose to listen to it loudly in a setting with moderate background noise, such as an office.


Overall, both the Bose 700 and QuietComfort 45 are excellent options for noise cancelling headphones. Whether you prioritize sound quality, comfort, or design, these headphones are sure to meet your needs.

To make an informed decision, be sure to consider all factors and weigh out the pros and cons of each model. If you’re ready to take the plunge and purchase one of these models, head over to the Bose website and get started today!
