Bose updates QC45 ANC headphones with adjustable EQ

The Bose QuietComfort 45 (QC45) are among the best noise-canceling wireless headphones you can buy. But unlike most of the competition, Bose did not equip the QC45 with the ability to control their equalization. That was a surprise, given that the older (but pricier) Bose Noise Cancelling Headphones 700 have adjustable EQ. Thankfully, that omission has now been addressed via a new firmware update that adds a three-band EQ to the Bose Music app.

In typical Bose fashion, the new EQ setting is a simple and clean affair. You get three sliders (bass, mid, and treble) and four presets (bass boost/bass reducer and treble boost/treble reducer). You likely won’t be surprised to learn that each of these presets does exactly what it says it will do. There’s also the ability to manually move each slider to your desired positions by using one of the presets as a starting point, or by hitting the reset button and then manipulating the sound from a neutral baseline.

Unfortunately, there’s no way to save a manual setting so that you can quickly return to it later. That seems like a big oversight given that those who actually enjoy dialing in their sound signatures don’t want to have to do it again and again. Moreover, some folks may find that a setting that works admirably for one genre of music may not suit other genres. Here’s hoping that Bose gives this some thought and provides this functionality with a future firmware update.

Still, this one critique aside, it’s great to have EQ flexibility on the QC45. There’s no denying that their default tuning is really well-balanced, but sometimes, balanced just isn’t what you want. For fans of bass, being able to pump the low end is a welcome addition, while those who listen to podcasts might just want to avail themselves of the treble boost mode to sharpen up the sound of voices.

I also like the fact that these EQ changes don’t rely on the Bose Music app to work. Once you set your preferred sound, that’s what you’ll hear from your mobile phone, a connected computer, or any other wired or wireless device if you keep the headphones powered on. Sadly, there’s no way to hold onto the customized settings when you turn them off and simply use them as a passive set of wired headphones — they need to be able to engage the onboard digital circuitry to process the EQ parameters.

What is Dolby Atmos Music, and how can you listen to it at home and on the go?
best tech under $100

Whether we get our music through streaming services, satellite radio, CDs, or vinyl, most of it has been recorded using the time-honored technique of two-channel stereo. But over the past few years, there's been a growing movement in the recording industry toward so-called spatial audio formats. The most popular of these formats is Dolby Atmos Music, and it can make good ol' stereo sound like mono AM radio.

But what exactly is Dolby Atmos Music? How is it different than stereo? And what kind of gear do you need to listen to it at home and on the go? We've got everything you need to know to get on the Dolby Atmos Music train.

YouTube TV rolls out multiview: watch up to 4 NCAA games at once
An example of YouTube TV's multiview feature.

If you love college basketball and can process more than one game at a time, you're going to go bananas for YouTube TV's new multiview feature, which will be rolling out on a limited, early access basis starting March 14.  With multiview, you'll be able to pick up to four channels and see them all simultaneously, with the ability to easily flip the active audio from one to another. The new feature is compatible with any TV-based YouTube TV installations (streaming media players, smart TVs, and game consoles), but it doesn't yet work on mobile devices or computers.

Initially, multiview will only be available to select YouTube TV users, who will be chosen at random. But Google says the goal is to include every subscriber by the time NFL football season starts in the fall. Another limitation, at least for now, is that YouTube TV will preselect the multiview channels you can choose. At launch, only channels that carry NCAA tournament games will be included in that preselected list.
How to use YouTube TV multiview
If you're one of the lucky, randomly chosen users, you'll see an option to watch up to four preselected, different streams at once in your “Top Picks for You” section. After selecting multiview, you can switch audio and captions between streams, and jump in and out of a full-screen view of a game.
It's all about sports
At the moment, YouTube TV sees multiview as an enhancement of the sports viewing experience, so only sports content will be eligible. YouTube TV has had some big sports wins in 2022, including 4K coverage of the Soccer World Cup, and that trend will continue in 2023 thanks to its acquisition of the NFL Sunday Ticket games. However, YouTube TV recently lost access to MLB Network and the add-on, which reduces the amount of sports content available for multiview in 2023.

Pioneer electronics makes some of the best AV receivers money can buy, and its flagship Pioneer Elite brand is about to push that envelope further with the announcement of its latest AVR (audio video receiver), the Elite VSX-LX805. The 11.2.4-channel network receiver will be available this Spring for a premium $2,999, but that big price gets you big power at 150 watts per channel, a new 32-bit digital audio converter, some AI-driven room calibration, and some audiophile upgrades.

The Pioneer Elite VSX-LX805 is the first Pioneer receiver to be designed in cooperation with Premium Audio Company since its licensing agreement with Pioneer/Pioneer Elite in 2021, which put them in charge of marketing and selling the brands' AVR business globally (except in China). PAC is a powerhouse of home audio gear, with huge brands under its umbrella, including Klipsch, Onkyo, Teac, and Energy, so expectations are high for its new arrivals.
