Sony and Bose have dueled over the top spot in the noise canceling space for years, and while Sony has held onto the crown in recent years, the Bose QuietComfort 45 makes a case to take it back. For the price, the Sony WH-1000XM4 is still one of the best pairs of noise canceling headphones on the market — even though the new WH-1000XM5 has been available for quite some time. Additionally, we think the QuietComfort 45 is still a better buy than the newer Bose QuietComfort Headphones. So, let’s find out how these two stack up.

Sony WH-1000XM4 vs Bose QuietComfort 45: Design and build

Meet the new QuietComfort 45, a very similar model to the QuietComfort 35 II.

True to its name, the Bose QuietComfort 45 is a bit more comfortable than the Sony WH-1000XM4. Bose’s headset is lighter than Sony’s (240g compared to 254g), and with that lighter weight comes a slightly smaller footprint. While the Bose QuietComfort 45 and Sony WH-1000XM4 look very different from each other, they have something in common—both headsets look almost identical to their respective predecessors.

The Bose QC 45 swaps in a USB-C charging port but looks otherwise the same as the QuietComfort 35 II. The WH-1000XM4 does even less to distinguish itself from Sony’s previous headset, with slightly thicker ear pads and a visible sensor inside the left ear cup. This isn’t necessarily a bad thing. Both the WH-1000XM3 and QC 35 II are easy to use and comfortable to wear, and that’s still true for the newer headphones.

The QuietComfort 45 is built mainly of plastic, with a foldable design that makes for a compact, portable pair of headphones. The headphone hinges also rotate to let it lay flat. The QC 45 features on-ear controls in the form of physical buttons, and they’re fairly intuitive. There’s an array of three buttons on the back of the right headphone—governing volume and playback control—and a button for toggling noise canceling on the back of the left headphone. Here’s what everything does by default:

The Sony WH-1000XM4 also features a plastic build with a frame that folds up and hinges that rotate to lay flat. Like its predecessor, its on-ear controls are a mixture of buttons and touch commands. There are buttons for power and toggling through the active noise cancelation and transparency modes on the back of the left headphone, and the side of the right headphone is touch sensitive—various taps and swipes handle playback and volume control.

What Bluetooth codecs do the Sony WH-1000XM4 and Bose QuietComfort 45 support?

The headphones have hinges so you can fold them to toss in your bag, and the earcups can rotate 90 degrees.

The Bose QuietComfort 45 and Sony WH-1000XM4 feature largely similar connection options, with a couple of differences. The QC 45 connects to your device of choice using Bluetooth 5.1 and supports the default SBC and AAC codecs. The WH-1000XM4 connects using the slightly older Bluetooth 5.0, but it also supports Sony’s own high-quality LDAC codec, in addition to AAC and SBC. Neither headset uses Bluetooth 5.2, so there’s no chance either will support Bluetooth’s upcoming LC3 codec.

If you’re an iPhone user, either headset should present virtually the same connection strength and audio quality due to the AAC support. However, if you use devices outside of Apple’s ecosystem, only the Sony headphones offer a reliable high-quality audio codec—AAC can be a little inconsistent on Android devices.

Both the QC 45 and WH-1000XM4 also offer Bluetooth multipoint, and each headset has a headphone jack for wired, lossless listening.

Does the Sony WH-1000XM4 or Bose QuietComfort 45 have better active noise canceling?

Both the Bose QuietComfort 45 and Sony WH-1000XM4 offer big improvements over their predecessors in the active noise canceling (ANC) department, but how do they compare to each other?

Loading chart ...

The Sony WH-1000XM4 features better passive isolation from 200-1000Hz than the Bose QuietComfort 45, but the Bose’s ANC outstrips it in that range—reaching nearly 40dB of attenuation, which means noises in that range will sound one-sixteenth as loud. With frequencies higher than 1000Hz, the superior isolation of the QuietComfort 45 further widens the gap.

Both headsets handle the kinds of sounds that ANC affects most very well and very similarly. However, the reduction in high-end, incidental noise—what passive isolation affects the most—is considerably more significant with the Bose QuietComfort 45. Something to note: turning off ANC on the Bose QC 45 immediately turns on aware mode, whereas with the Sony WH-1000XM4, you can disable both modes for a standard listening experience.

To achieve a result similar to what our ANC charts indicate, you must get a proper seal with the headphones around your ear. If gaps form between the padding and your skull, then external noise will make it through the physical barrier of the headset and render both passive isolation and ANC far less effective. Both headsets have oval-esque ear pads that should accommodate most ear sizes, so getting a proper fit should be fairly simple.

Does the Bose QuietComfort 45 sound better than the Sony WH-1000XM4?

The Sony WH-1000XM4 doesn’t look too different from the originals except for a few slight tweaks.

The Sony WH-1000XM4 and Bose QuietComfort 45 have largely pretty similar frequency responses, with a couple of key differences. For starters, the Sony headphones add considerably more bass emphasis than the QC 45. However, while both headsets sport more high-end emphasis than our house curve (pink), the Bose QuietComfort 45 starts adding emphasis at a considerably lower frequency—around 2000Hz.

While neither of these kinds of audio profiles are ideal, you’re probably going to have fewer issues with Sony’s headphones. The increased bass response isn’t so overbearing that it will cause too much auditory masking, and the increased mid-range audio means vocals should come through nicely. Conversely, the over-emphasized highs of the Bose QC 45 can sound pretty unpleasant, even if your volume isn’t that high.

You can EQ the WH-1000XM4’s frequency response from the Headphones Connect app and the QuietComfort 45’s frequency response in the Bose Music app with the latest firmware installed. Sony’s multi-band equalizer is very effective, while the Bose EQ is a bit more limited, though it’s still somewhat granular.

Does the Bose QuietComfort 45 have better battery life than the Sony WH-1000XM4?

The WH-1000XM4 has a ton of Bluetooth codec options but, thankfully, still has a place for a standard 3.5mm audio cable as well.

According to Sony, the WH-1000XM4 headphones can last 30 hours of consistent playback on a single charge. However, at a consistent output of 75dB(SPL), we found the headset lasted a minute shy of 20 hours. Again, this is a very solid result but hardly the stellar one advertised. On the other hand, the Bose QuietComfort 45 lasted 24 hours and 49 minutes—surpassing Bose’s official 24-hour battery life for the headset.

Both headsets charge over USB-C, and they both offer varying fast charging performance. A 15-minute charge yields 180 minutes of playtime for the Bose QuietComfort 45. However, that pales in comparison to the Sony WH-1000XM4, which grants 5 hours of listening time after a mere 10 minutes of charging. Of course, you can also listen over either headset over a wired connection with the included 3.5mm cords (or 2.5 mm-3.5 mm cord, in Bose’s case).

Is the Bose Music app or the Sony Headphones Connect app better?

The app doesn’t offer much in the way of features, so those looking to EQ their headphones will be disappointed.

Both the Bose QuietComfort 45 and Sony WH-1000XM4 bring companion apps to unlock additional features, but the options are far from equal.

The Sony Headphones Connect app brings options for customizing one of the buttons on the headphones—you can set it to either toggle between noise canceling modes or turn on your virtual assistant, and you can decide between Google Assistant and Amazon Alexa as the default virtual assistant. Additionally, the Sony Headphones Connect app also brings the ability to optimize noise canceling and set up Sony’s 360 Reality Audio. This is a new standard for mastering music in surround sound, and available through Deezer, Amazon Music, and Tidal Hi-Fi. Oh yeah, and you can do more mundane things like customize the headphone EQ, prioritize connection stability over sound quality, and access firmware updates.

In comparison, the Bose Music App asks you to share a lot of information: your location, call and message history, and in return, it gives you access to firmware updates and an equalizer. There’s a little more to it than that, as you need to app to get virtual assistant integration set up and choose the name of your headset. This could eventually change—Bose has made a habit of putting out pretty significant features in updates after launch, with the EQ being a recent example.

Does the Sony WH-1000XM4 or Bose QuietComfort 45 have a better microphone?

This is an embedded microphone, so the quality is limited.

Neither the QC 45 nor the WH-1000XM4 have what you’d call a high-end microphone. They’re both loud and clear enough to handle whatever your phone call needs are but don’t expect anything approaching studio quality. Neither one really sounds better than the other, so you won’t need to worry about making this sort of trade-off, at least.

Sony WH-1000XM4 vs Bose QuietComfort 45: Which headset should you buy?

The WH-1000XM4 has a ton of Bluetooth codec options, but thankfully still has a place for a standard 3.5mm audio cable as well. The Bose QuietComfort 45 may be the newer option by far, but that doesn’t necessarily make it a slam dunk. Sure, it’s cheaper by about $20, but in saving that money, you lose out on a fully-featured app, vastly superior quick charging, and a more pleasant default sound profile.

The ANC performance of the WH-1000XM4 may have lost a bit of its luster in the last little while, but it’s still among the best noise canceling headphones on the market and keeps pace competitively with the QC 45. The real standout improvement of the QC 45 is its noise canceling, but given all the other things, it’s just not a big enough difference to make this an easy decision.

An exceptional pair of noise canceling headphones.
High-quality Bluetooth codecs, great sound, improved noise-canceling, good battery life, and smart features like auto-pause and Bluetooth multipoint make the Sony WH-1000XM4 a great all-round pair of headphones.

All the same, both headsets are very good, and you likely won’t be disappointed with either. If your budget is a little restricted, the Bose QuietComfort 45 will still get you from A to B, and Bose often adds new software features down the line, with the EQ being a notable recent addition. If you’re an Android user and still vacillating between the two, remember that only the Sony headphones include a high-quality audio codec for you. Since neither headset uses Bluetooth 5.2, LC3 isn’t coming—what you get is what you get.

What should you get instead of the Bose QC 45 or Sony WH-1000XM4 wireless headphones?

One of the biggest competitors on the market here is the Apple AirPods Max. iPhone owners will likely already be familiar with this option, and if you own one, then this is likely the ideal choice for over-ear, active noise canceling headphones. It offers a bunch of extra features, including Siri integration and Apple Spatial Audio. Another alternative is the Sennheiser MOMENTUM 4 Wireless, which sounds fantastic, although does fall a little short when it comes to ANC performance.

You may be interested in the new Sony WH-1000XM5, an updated version of the XM4 with a completely new design and even better noise canceling, alongside improvements to sound quality and microphone quality. Finally, there’s also the latest Bose QuietComfort Headphones to coonsider, the successor to the QC 45’s. Apart from a new coat of paint and a changed sound profile, there aren’t enough new features to justify paying more for the newer model.

Frequently asked questions about Bose QuietComfort 45 vs Sony WH-1000XM4

The Sony WH-1000XM3 is now two product generations old but can be found quite cheaply nowadays. You may be interested in picking it up, as it still has pretty decent sound quality and active noise canceling. That being said, in many ways, it’s been surpassed by the newest generation of ANC headphones.

Sony’s Headphone Connect app brings support for the company’s 360 Reality Audio, which is spatial audio, but that only works with files designed for the standard. Bose doesn’t have its own spatial sound feature, but both the QC45 and WH-1000XM4 will work with third-party options like Dolby Atmos for Headphones when connected to a PC. However, Apple’s Spatial Audio feature won’t work with either.
