Bowers & Wilkins updated its Pi7 and Pi5 earbuds with better battery life

Bowers & Wilkins debuted its first true wireless earbuds in the spring of 2021. In fact, it announced two models at that time: the Pi7 and Pi5. Today, the company revealed updated versions for both which will carry the S2 label Bowers & Wilkins typically uses for retooled but not entirely brand new products. While the Pi7 S2 and Pi5 S2 aren’t rebuilt from the ground up, there are still some notable upgrades to both.

The Pi7 S2 and Pi5 S2 now both offer five hours of battery life on a charge. That’s up from four hours on the Pi7 and Pi5. A 15-minute quick-charge feature still gives you two hours of use and the included cases carry an additional 16 hours for the Pi7 S2 and 19 hours for the Pi5 S2. Both still have wireless charging capabilities, though the case for the Pi7 S2 is equipped with Wireless Audio Retransmission. Like it did for the Pi7, the case can connect to can external audio source — like in-flight entertainment — and wirelessly send sound to the earbuds. This isn’t novel to Bowers & Wilkins earbuds, but it is a handy feature nonetheless. Bowers & Wilkins says it also updated the antenna design on the Pi7 and Pi5 to increase Bluetooth range up to 25 meters. 

The key difference between the two models is audio quality. The Pi7 S2 supports aptX Adaptive with 24-bit/48kHz streaming from compatible devices and services. 9.2mm balanced armature dynamic drivers are paired with Bowers & Wilkins’ digital signal processing tech for higher quality audio that what the Pi5 offers with CD-quality sound and regular aptX. The Pi7 S2 also packs one additional microphone per earbud which should make it the preferred option for calls. And while both feature active noise cancellation (ANC), the Pi7 S2 has an adaptive setup that automatically monitors your surroundings to adjust the audio as needed for “the best possible, uninterrupted listening experience.” 

Both the Pi7 S2 and Pi5 S2 are available starting today, replacing the Pi7 and Pi5. The $399 Pi7 S2 comes in black, white and dark blue color options while the $299 Pi5 S2 offers light grey, dark grey and purple. A green version of the Pi5 S2 is slated to arrive later this spring.

The best wireless headphones for 2023

Over-ear noise-canceling headphones typically offer the most comprehensive set of features we want for our listening pleasure. The best of these wireless options combine stellar audio with powerful active noise cancellation (ANC) and other handy tools to create as complete a package as possible. Of course, some companies do this better than others. For Engadget’s best wireless headphones guide, we tested out a number of different models with a variety of features, including noise cancellation and sound quality. Plus, our favorites span a range of prices so you can decide how much you’re comfortable spending.

Best overall: Sony WH-1000XM5

Sony’s 1000X line has been our top pick for best wireless headphone for a long time now. Until another company can pack in as many features as Sony, and do so with a stellar mix of sound and effective ANC, the crown is safe. With the WH-1000XM5, Sony redesigned its flagship headphones, making them way more comfortable to wear for long periods of time. The company also made noticeable improvements to the active noise cancellation, adding a separate V1 chip in addition to the QN1 that was inside the M4. There are now eight total ANC mics as well – the previous model only had four. This all combines to better block ambient noise and high frequencies, including human voices.

The 1000XM5 still has all of the features that typically make Sony’s top-of-the-line headphones showstoppers. That includes 30-hour battery life and crisp, clear sound with balanced tuning and punchy bass. A combo of touch controls and physical buttons give you on-board access to music, calls and noise modes without reaching for your phone. Speak-to-Chat automatically pauses audio when you begin talking, and like previous Sony headphones, the M5 can change noise modes based on your activity or location. Plus, this model offers better call quality than most of the competition. The only real downside is that they’re $50 more than the WH-1000XM4 at full price ($400).

Runner up: Bowers & Wilkins Px7 S2

I’ll admit I didn’t expect Bowers & Wilkins to make the year’s best headphones list, or even be in contention for a spot. However, the company’s revised Px7 headphones impressed me during my review. The Px7 S2 are pricey at $399, but Bowers & Wilkins pair impressive audio quality with solid ANC performance. In fact, the Px7 S2 are my favorite headphones right now in terms of sound. There’s also a more refined design that doesn’t look overly plasticky and the headphones fit comfortably even after hours of use. Call quality, ambient sound and automatic pausing aren’t the best here, but they get the job done. At the end of the day, the design, sound quality and noise cancellation make the Px7 S2 a strong pick in the current true wireless headphone field.

Best budget: Audio-Technica ATH-M20xBT

Audio-Technica has introduced affordable wireless headphones in the past, and while they didn’t offer active noise cancellation, they’re still worth considering. The company’s latest is the M20xBT, a Bluetooth version of the A-T’s popular M20x wired cans. For just $79, you can expect a comfy fit and up to 60 hours of battery life. Bluetooth multipoint connectivity allows you to connect to multiple devices at once and physical buttons provide reliable on-board control. The design isn’t as refined as the company’s pricer models like the M50xBT2, but you get the bulk of what makes Audio-Technica’s cheaper options so good.

Another solid option: Bose QuietComfort 45

The Bose 700 was one of our top wireless Bluetooth headphones last time around, but the company recently revived a workhorse with the QuietComfort 45. The design is mostly unchanged from the previous QC models, which could be a deal breaker for some. Once you get past that though, the QC45 combines Bose’s excellent active noise cancellation with clear and balanced audio. You can expect up to 24 hours of battery life on a charge and a comfortable fit that doesn’t get tiresome during long listening sessions. We’ve already seen them on sale for $50 less than full price, which makes the QuietComfort 45 even more compelling.

Another solid option: Technics EAH-A800

Back at CES, Panasonic announced the EAH-A800: a new set of active noise canceling headphones under the iconic Technics brand. While most of the features are what you see on any number of headphones, one figure stood out. The company says you can expect up to 50 hours of battery life on the A800, and that’s with active noise cancellation enabled. These are currently in my stable of review units for detailed analysis, but I have already tested them on a long flight. The ANC is impressive and they’re comfortable enough to avoid becoming a burden after several hours. Sound quality is also quite good (there’s LDAC support, too) and there are enough features here to justify the premium price tag.

Another solid option: Master & Dynamic MW75

While Master & Dynamic is known for its design prowess, the company’s over-ear headphones were due for a refresh. With the MW75 that debuted in June, the company opted for a look that takes cues from its MG20 gaming headset and mixes them with a combo of aluminum, leather and tempered glass. The company’s trademark sound quality returns with multiple ANC modes and ambient sound options for a range of situations. At $599, the high-end looks don’t come cheap, but if you’re looking for something beyond the pure plastic fashion of most headphones, M&D has you covered.

Another solid option: Sennheiser Momentum 4

I’ll be honest, I had a hard time choosing between the Px7 S2 and the Momentum 4 for the runner-up spot this time around. However, Bowers & Wilkins gets the edge in terms of design even though the Px7 S2 and the Momentum 4 are very evenly matched on sound quality. They’re the two best-sounding sets of Bluetooth headphones I’ve tested this year – and it’s not even close. Sennheiser does have an impressive 60-hour battery life in its favor and improved ANC performance. Those two items alone might be enough for you to overlook the very generic design.

Apple’s larger HomePod returns with upgraded audio and more smart home tools

Apple discontinued its original HomePod smart speaker in 2021, choosing instead to focus on the cheaper mini version of the device. Today, the company has resurrected the bigger unit with several notable updates along the way, including upgraded audio,…

The best portable Bluetooth speakers for 2023

If there’s one thing I’ve learned about today’s Bluetooth speakers, it’s that for general consumers, the options are pretty good. However, that doesn’t make the process of sifting through the dozens of choices any easier. So I set out to test out some …

Astell & Kern’s latest mobile DAC brings 32-bit audio with fewer sacrifices

If you’re determined to listen to high-resolution audio on your phone using high-end earphones, you’ll want a DAC — and Astell & Kern thinks it has one of the better options. The company has introduced its third USB DAC, the AK HC3, and this one may finally nail enough features to satisfy most users. It promises very high-quality 32-bit, 384kHz audio like its HC2 predecessor, but you can finally use your headset’s microphone. You won’t have to choose between pristine sound and making phone calls.

The AK HC3 also uses ESS’ newer ES9219MQ dual DAC. A built-in LED even shows if you’re using a high-res audio format. The USB-C connection supports Macs, Windows PCs, Android phones and many tablets (including recent iPads), but there’s an included Lightning adapter in the box for your iPhone. Android users get a dedicated app to fine-tune the output.

Astell & Kern will sell the AK HC3 for $229, with pre-orders starting January 20th and a release estimated for February 13th. This isn’t the absolute highest-quality DAC (Fiio’s Q3 can manage 768kHz), but it’s better than many mobile options and is relatively easy to carry.

There are two similarly new headphone amps if you’re more interested in quality than size. The Acro CA1000T is a second-gen “carriable” model that uses ESS’ new high-end ES9039MPRO dual DAC and a triple amp system that lets you switch between dual vacuum tubes, normal amping and a hybrid that combines both technologies. It arrives alongside the HC3, although the $2,299 price will limit it to well-heeled audiophiles.

The AK PA10 portable, meanwhile, is Astell & Kern’s first device with a Class-A amp. The choice promises the “best” linear output and a warm, natural sound for 12 hours of battery-powered use. It also won’t be cheap when it arrives on February 13th for $599, but it may be worth considering if you want a balance between portability and raw technical prowess.

Dolby Atmos for cars hands-on: Immersive spatial audio hits the road

Dolby Atmos for cars was first announced for the Lucid Air and select Mercedes models in 2021. But with the immersive audio making it to luxury automobiles in the US last month, the company is showing off the setup here at CES 2023 with in-car demos. We got our first listening session in the backseat of a Mercedes-Maybach S 580. 

First, let me explain a bit about the car. This Maybach is equipped with a Burmester 4D sound system with 30 total speakers, six of which are in the ceiling. Think of those as playing the role of upfiring drivers in your Atmos soundbar. Amplifiers deliver 1,750 watts of power and both front- and trunk-mounted subs handle the bass (the trunk sub has its own 400-watt amp too). It’s a completely insane setup installed in a $185,000 car.

The immersive sound is so impressive, it even manages to upstage its lavish setting. It’s great for pop tunes like The Weeknd, but much like an Atmos system in your home, the in-car version really shines with genres like jazz. When listening to “So What” from Miles Davis’ Kind of Blue, it felt like I was in a club. In the backseat, the drums were to my right while the horns were up by the driver and so on. The sensation was like sitting in the middle of all the musicians while they did their thing. As someone who has tested several Atmos home theater setups, I was still surprised by the results here. Of course, this is a crazy sound system in high-end luxury car, likely the best iteration of this type of Dolby automotive collab.

Right now, the bulk of the content is audio. Simply link your streaming service of choice, so long as it offers Dolby Atmos Music spatial audio, and you’re all set. The infotainment system in the Maybach had all of the compatible tunes clearly labeled as to which were Atmos. Dolby says there are some companies offering a/v uses, so movies and shows with the immersive audio would sync up with an in-car setup just fine. The company’s senior vice president of entertainment John Couling explained during the demo that he anticipated people would watch movies mapped in Dolby Atmos while their EV charged, for example.

Dolby says Atmos was designed to be scalable from the start, so just like it has for soundbars, the audio platform can be configured for more run-of-the-mill speaker setups in more affordable cars. We’re talking four-channel, six-speaker arrangements. It wasn’t so long ago that Atmos was reserved for only premium soundbars and now it’s available on things like the Sonos Beam via virtualization. So even though a family car or minivan may not have the ceiling-mounted overhead speakers a Mercedes does, immersive audio won’t be out of the question. Much like it’s interesting to see how more budget-friendly speakers handle Atmos, I’m looking forward to hearing what a virtualized version sounds like in a Honda Civic. 

Dolby Atmos is currently available on the Lucid Air and Mercedes-Maybach S-Class, as well as the Mercedes-Benz S-Class, EQE, EQE SUV, EQS and EQS SUV. Volvo has already announced that Atmos will be available on the Bowers & Wilkins sound system in the EX90 SUV. The EV will be the first Volvo to have Dolby’s immersive audio inside. The Polestar 3 also packs an Atmos-equipped Bowers & Wilkins setup and it’s due to arrive later this year. The Plus pack specifically includes a 25-speaker system for this task. Lotus has also announced a collaboration with Dolby, bringing Atmos to the KEF setup inside the Eletre EV that’s due to debut in 2024. 

Android’s media player could make it easier to move audio between speakers and headphones

Google is working on ways to make it easier for folks to switch audio playback to another device when they listen to music or podcasts via Android. The company says it’s collaborating with Spotify to let you swiftly move what you’re listening to from one Spotify Connect-supported device to another, all from the Android media player.

Android 13 features a redesigned media player with a notification section that enables YouTube and YouTube Music users to quickly change which compatible Bluetooth or Chromecast built-in devices they’re playing audio or video on. Spotify integration could make things a bit more straightforward for folks who move audio playback from one speaker or TV to another when they go to a different room, for instance, or if you want to change from single-speaker playback to blasting music throughout your home.

In addition, Google says it’s working on a related audio handoff feature. When you move from one place to another, you’ll see media notifications asking if you’d like to shift the audio to a nearby device. So, when you leave home, your Android phone might ask if you want to transfer your music or podcast from a speaker to your headphones, and then to Android Auto once you’re in your car. Google is working with Spotify and YouTube Music teams to add integration for those services. Spotify started testing a similar feature in its own app in 2019.

Audio-Technica adapted its popular M50x headphones into headsets

At CES, Audio-Technica unveiled new StreamSet wired headsets that it designed with content creators in mind. Based on the popular M50x headphones, the M50xSTS comes in two flavors. One model has 3.5mm aux and XLR connectivity. The other has a USB cable that enables some extra features, but the two versions are otherwise very similar.

You’ll get the same 45mm large-aperture drivers with rare earth magnets and copper-clad aluminum wire voice coils that are present in the M50x, along with swappable earpads. The M50x earpads are focused on audio quality and sound isolation, while the mesh and leatherette earpads are all about breathability and comfort.

As for the microphone, Audio-Technica adopted a cardioid condenser from its 20 Series models. The mic, which is said to offer studio-level audio quality without background noise, is on a boom arm. Handily, when you flip the boom up, the headset will mute the mic. One advantage that the M50xSTS-USB has over the 3.5mm model is that, thanks to the sidetone circuitry, you’ll be able to hear your voice through the headset if you wish. You can adjust that volume with an earcup dial.

The M50xSTS has a two-meter cable with a 3.5mm headphone input and, for the mic, an XLR output that you can connect to an audio interface or mixer. The M50xSTS-USB version has a two-meter cable as well, but with a USB-A connector (you’ll get a USB-C adapter too). The latter model also has an analog-to-digital converter with a sampling rate up to 24 bits or 96 kHz. The M50xSTS costs $199, while the M50xSTS-USB will run you $229.

Sennheiser’s Conversation Clear Plus are hearing aids in disguise

It’s taken longer than we’d hope, but since October, the FDA finally established a framework for new category of hearing aids that don’t need a medical exam, prescription or a fitting by an audiologist. Unsurprisingly we’re seeing the first OTC products being announced at CES. Sennheiser, a mainstay of the consumer audio world, is tossing its proverbial hat into the ring with the Conversation Clear Plus.

As the name suggests, the focus appears to be on dialogue (rather than the holistic hearing experience). Sennheiser says the earbuds will make it easier to understand conversations in noisy environments. This, the company claims, is achieved in a number of ways. At the heart of the device is a Sonova chip. Sonova is behind some of the legacy names in hearing aids such as Phonak and Unitron and it also bought Sennheiser’s consumer audio business about 18 months ago.

The Conversation Clear Plus looks a lot like a pair of regular true wireless headphones which will go a long way to removing any stigma or association with conventional hearing aids. Unsurprisingly, they do share a lot of features with regular headphones too. That includes active noise cancellation, even if the application here is more focused on reducing background noise in relation to dialogue.

Like most wireless headphones you’ll have the option to adjust the amount of noise reduction and there’s a companion app for further tuning your hearing experience. Sennheiser says there are three main prestets: Relax, Communication and Streaming. Those are all fairly self explanatory, but the last one marks a key difference between this category and legacy hearing aids — the ability to stream music and audio from your phone. Some hearing aids can do this, but it’s often a sub-optimal experience given that it’s not what they were primarily designed for. Given Sennheiser’s credentials in the headphone world, it seems likely streaming will be comparable to its consumer headphones.

On a more practical note, the Conversation Clear Plus offers a nine hour battery life per charge, with an additional 27 hours/three charges available via the case.

One of the big promises with OTC hearing aids was a significant reduction in cost. Typically a set with a fitting from an audiologist would cost several thousand dollars, the Conversation Clear Plus will retail for $850. The experiences between the two different product categories will obviously be somewhat distinct, given the different form factor, but the modern, gadgety design will appeal to a lot of folks that might otherwise be turned off by the clinical design of classic hearing aids.

The Conversation Clear Plus will be available for pre-order starting Jan 5 and will go on general sale Jan 20.
