Build Quality and Comfort

The Bose QC45 are more comfortable, but the Bose 700 are better built.

You can get the Bose QC45 (left) in white or black while the Bose NCH 700 (right) are available in black and silver.

Looks-wise, the Bose QC45 and NCH 700 can’t be more different than each other. While they both have modern and minimalist looks, the QC45 have a more traditional headphones design while the Bose 700 have a more futuristic look. The main difference is with their headbands. The QC45’s headband has yokes at the end for a more standard look, whereas the 700 have a thinner headband that connects directly to the ear cups. As far as looks go, we definitely like the design of the Bose 700 better.

When it comes to build quality, Bose 700 have the advantage. That’s not to say that the Bose QC45 are built poorly, in fact they have a good build quality. However, the Bose 700 are built with better quality materials and they feel more premium to the touch. Also, the Bose 700 have fewer moving parts that can be potential weak points. Their headband is adjustable and their ear cups can swivel, but that’s it. Meanwhile, the Bose QC45 also have an adjustable headband and folding ear cups, but they are also collapsible, which is great for portability, but increases the number of potential weak points in the construction.

True to their name, the Bose QuietComfort 45 are very comfortable headphones. They have a more relaxed clamping force than the Bose 700, they are lighter and their ear cups are deeper so they can fit more ear sizes. In contrast, the Bose 700 have a tighter clamping force and their ear cups are a bit shallow.


You get better ANC with the Bose QC45, but the Bose 700 have more versatile controls.

The Bose QC45 headphones (left) have physical buttons for controls, while the Bose 700 (right) have both touch and physical buttons.

Active noise cancellation performance is close between these two headphones. The Bose QC45 have two modes—Quiet and Aware. Quiet mode blocks noise from the outside while Aware mode amplifies your surrounding’s sound for better awareness. Meanwhile, you can adjust the ANC level on the Bose 700 from 0 – 10, so there’s a level of customization given to the user.

That being said, ANC effectiveness definitely goes to the Bose QC45 even though the Bose 700 are the more expensive pair. Both are excellent and they are among the best in the market, but we found the QC45 to be more effective when blocking out noise throughout the mid-range. They perform the same throughout the low and high frequency noise.

The controls on the Bose QC45 are exactly the same as the QC35, with buttons on both earcups. On the other hand, the Bose 700 have both touch and physical controls. The simplicity of the QC45’s controls is nice, but having both touch and physical buttons on the 700 may be preferred by more people. Extra features of the Bose 700 include built-in Alexa and Google Assistant as well as Spotify Tap.

Sound Quality

Both the Bose QC45 and 700 will sound good enough for most people, but one advantage of the latter is better microphone quality.

The Bose QC45 headphones (left) are more comfortable than the Bose 700 (right) due to thicker padding on the earcups.

When it comes to sound quality, the Bose QC45 have boosted bass and treble with a fairly flat mid-range. Meanwhile, the Bose 700 also have boosted bass, but not to the same level of the QC45. Their mids are accurate and balanced, but the treble is underemphasized.

The Bose QC45 deliver a slightly brighter sound with more details due to their boosted treble, however, the bass can be a bit overpowering. The Bose 700 have a more veiled and dark sound due to having recessed highs. Fortunately, you can EQ both headphones to tweak the sound.

When taking calls, you’ll be heard clearly by the person on the other end. The sound quality is not the best, and it lacks richness, but you’ll be heard clearly, which is the most important. One advantage of the Bose 700 is their ability to separate your voice from your surrounding noise. The Bose QC45 might struggle if you are taking calls in a very busy environment.

Battery Life and Connectivity

The Bose QC45 have a longer battery life and faster charging than the Bose 700.

They come with the same accessories, except for the shape of their carrying cases.

The Bose QC45 outperform the Bose 700 in battery life and charging. The Bose QuietComfort 45 can last up to 24 hours on a full charge with ANC enabled, which is an improvement over the QC35, but still lacking when compared against Sony’s WH-1000XM4. They have a 5-minute quick charge that gives the headphones 2.5 hours of playback time.

On the other hand, the Bose 700 have a battery life of up to 20 hours with ANC enabled. Not as good as the QC45’s, but still decent. They also have a quick charge feature—15 minutes of charging gives you two hours of listening time.

As for connectivity, you can use both headphones either wired or wirelessly. They come with a 3.5mm analog cable for wired listening, so you can use them on devices other than your phone.


The Bose QuietComfort 45 have a slightly better ANC and battery performance, and they are more comfortable than the Bose 700, which have more features and better build quality.
