Apple re-releases AirPods Max lossless audio update after initial delay

Apple has begun seeding a new update for the AirPods Max after hiccups in the initial rollout. The recent update, brought alongside iOS 18.4 earlier this week, enables lossless audio and super low latency when using the headphones over USB-C.

Apple’s support page listing AirPods firmware updates was recently updated to indicate the said program, with build number 7E101, was now available for the AirPods Max. This succeeds the previous 7E99 build that was initially released this week but later marked as “Coming soon.” YouTuber Aaron Zollo shared a screenshot on X, confirming the change.

Shortly after, Apple released the update on Tuesday, we encountered several reports about people being unable to download the update due to an unknown limitation, presumably in iOS 18.4. Understandably, the update only applies to the newer version of AirPods Max with a USB-C connector, and not the older versions with Apple’s formerly favored Lightning Connector.

The update is crucial as it finally enables the AirPods Max to work over a USB connection instead of Bluetooth. More importantly, wired connection also enables 24-bit, 48kHz Lossless audio using Apple’s proprietary ALAC audio format. Apple says the feature preserves “preserving the integrity of original recordings and allowing listeners to experience music the way the artist created it in the studio.” In addition, the feature can also be accessed using a new USB to 3.5mm cable that Apple announced earlier this week.

Besides lossless audio, the update brings Spatial Audio with head tracking features along with ultra low latency when the headphones are connected to a supported Apple device over a wired connection.

Once you update your iPhone to iOS 18.4 (or iPad or Mac to the latest stable builds), you should now see the update in Bluetooth settings. Tap the “i” button next to AirPods Max in the list of devices to see the available firmware version and updates.

Since the updates happen automatically while you’re not using the AirPods, Apple suggests you charge your AirPods and keep them around your iPhone, iPad, or Mac for at least 30 minutes. After waiting, place the AirPods Max over your ears again to connect them to your Apple device. The AirPods Max will have updated by now. If that doesn’t happen, you might have to reset your AirPods (here’s how to) to receive the latest update.

Apple might arm AirPods with live translation facility this year

Apple has lately focused on giving the AirPods more of a wellness-focused makeover than hawking them as plain wireless earbuds. Late last year, the AirPods Pro 2 landed a Loud Sound Reduction feature, alongside a hearing test system and hearing aid facility.
Now, the company is reportedly eyeing a conversational upgrade for them. According to Bloomberg, Apple plans to bring a real-time translation facility to the AirPods later this year. The focus is on removing the language barrier for in-person conversations.
The feature is said to be in active development and might be rolled out via a software update later this year, tied to the iOS 19 bundle. It’s going to be a two-way translation system where the AirPods and iPhone play an equal role.

In a bizarre twist, AirPods Pro are cheaper in Canada … for now

Unless you've been hiding under a rock, it's been impossible to escape the headlines around the new tariffs imposed on Canadian, Mexican, and Chinese imports to the U.S. (or the many retaliatory tariffs that these countries have imposed on U.S. products). The expectation is that these tariffs will make certain goods more expensive, regardless where you live. But in a bizarre twist of timing, tariffs, and currency exchange rates, one particularly popular Apple product is cheaper in Canada than in the U.S.: the AirPods Pro 2.

Apple sells the AirPods Pro 2 in the U.S. for $249 and $329 ($CAD) in Canada. A quick look at current currency conversion rates shows that despite the higher number in Canada, that's actually the cheaper of the two prices. According to RBC Bank's currency calculator, if you hold U.S. dollars right now, you can buy $329 CAD for just $236 USD -- a $13-dollar savings.

Apple is eyeing AirPods with camera and health sensors as a priority

Apple CEO Tim Cook recently sat for an interview with Wired and dished on Apple’s focus in the foreseeable future. Health and wellness stood out as a recurring element. AirPods, which recently landed a hearing assistance facility, are visibly at the center of those ambitions. Now, Bloomberg reports that the earbuds will soon add cameras and health sensors to their arsenal.

At one point in time, Apple was reportedly working on integrating cameras into the wireless earbuds, but the project was put on ice. It seems that the recent explosion of AI-based workflows across nearly every product category inspired Apple to revive the endeavor.
