Stop Switching Devices Manually: Your Guide to Multipoint Bluetooth Audio
When you’re bouncing between your phone and computer, advanced multipoint Bluetooth connections allow you to connect to two or more devices simultaneously.
Jumping between digital devices has become a necessary part of many people’s daily lives, whether you’re keeping up with text alerts or ensuring you don’t miss an important call while in a Zoom meeting on your laptop.
Multipoint Bluetooth was designed to solve the problem of having to disconnect or enter the Bluetooth menu each time you want your headset to connect to a different device. It helps you stay notified of incoming calls, email or messaging notifications, letting you conveniently bounce between personal and professional without interrupting your task.
Introduced in 2010 as part of Bluetooth 4.0, advanced multipoint allows two devices to be connected simultaneously to your audio headset, enabling you to switch between them. For several years, the feature was glitchy, unreliable and not widely supported, particularly for true-wireless earbuds. But that’s changing.
Recent hardware and software advances have vastly improved multipoint’s stability and power consumption, and the feature is now available on many wireless headphones and true-wireless earbuds, including those from Bose, which was slow to adopt the feature due to reliability concerns.
Apple and Google support systems that behave similarly to multipoint — automatic device switching — which swaps source devices when it detects playback on your target device. The caveat is that they are technically fast auto-pairing systems rather than simultaneously connecting two devices, and you must be signed in to the same Apple ID or Google account on both devices for this function to work.

The advantages and limitations of multipoint Bluetooth
When multiple devices are within the same digital ecosystem — Apple, Samsung or Google — and you’re signed into the same account on them, you get smoother (and often automatic) switching, whether it’s via Apple’s Handoff, Google’s Fast Pair or actual multipoint Bluetooth.
If, for example, you’re swapping between your Apple iPad and your Android smartphone, you’ll usually have to pause one device manually (semi-automatic switching) before audio will switch over, though you still get the benefit of not having to do the Bluetooth disconnect/connect mambo.
Multipoint is not a universal feature, and its performance can vary depending on the specific model. Multipoint Bluetooth was (and still is) easier to implement on standard wireless headphones because the earcups are connected via a single main Bluetooth connection. True-wireless earbuds are more complex since the left and right earbuds have to be wirelessly synced while avoiding interference issues, and a third wireless channel (and more processing power) is required for multipoint pairing.
Note that multipoint Bluetooth doesn’t mean you can stream media from two devices simultaneously to the headphones. There are gaming headsets that support multiple simultaneous streams, but they use two distinct wireless connections — one by Bluetooth and one via 2.4GHz wireless — such as the HyperX Cloud Alpha 2 and Audeze Penrose. There are also models that can handle simultaneous sources by using wired and wireless connections.
Setting up multipoint Bluetooth
Update device firmware: Your phone, tablet and laptop should always be up to date, but it’s best to double-check to ensure your operating system supports the latest features.
Install the app: Download and install the companion app for your headphones or earbuds on your primary device, typically your phone, unless you use your tablet primarily for calls.
Pair with your primary device: Put the headphones or earbuds in pairing mode (usually by long-pressing a button on the headphones or case), and pair them with your phone or tablet using the device’s Bluetooth settings.
Update headphone firmware: Companies continually improve switching and connection reliability through firmware updates. To keep your headphones or earbuds current, update them via the app’s settings menu. Re-pair if necessary, and test the connection by streaming some audio.
Enable multipoint connection: Open the companion app settings again and enable your connection with a toggle switch labeled something like:
- Allow multipoint connection
- Connect to two devices simultaneously
- Pair with a second device
- Auto Switch
Pair with the second device: Put the headphones back in pairing mode and use the second device’s Bluetooth settings to pair them. Test the connection by streaming some audio.
What to expect from multipoint Bluetooth
At this point, you should be able to switch easily from one device to the other (and back) by starting a stream on the second device — or pausing the first one if your devices are from different operating systems (iOS and Android, for example). Note that due to Bluetooth bandwidth constraints, you may not be able to use certain «high-resolution» audio codecs like Sony’s LDAC while in multipoint mode.
It’s a good idea to test a few different scenarios with a mix of calls and media to see how things work with your particular mix of devices and apps. Even if all your gear is from the same ecosystem, you’re somewhat at the mercy of the apps you’re using and how they’re prioritized by the devices’ operating systems, as well as how they handle switching.
But if all goes well, you’ll be able to move more seamlessly between your digital devices than ever before, and you’ll wonder how you ever got along without multipoint Bluetooth.

Google races to put Gemini at the center of Android before Apple’s AI reboot
Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.
Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’
Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.
Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge
Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.
Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.
Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.
The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.
The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.
Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.
Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.
Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
