Last gasp AirPods Pro 3 report points to heart-rate monitor, plus bold iPhone 17 Pro colors

The AirPods Pro 3 and iPhone 17 Pro could look different, but the internals is where the real magic happens.

Apple’s “awe dropping” event later today is going to be a packed one, with four smartphones, three smartwatches, and potentially a smart home gear lined up as well. But according to Bloomberg’s Mark Gurman, Apple could deliver a couple of surprises atop its flagship phone and true wireless earbuds.

AirPods Pro 3 make the big leap

For a while, we have been hearing rumors of a big health-centric upgrade for the AirPods Pro. Apple has reportedly been experimenting with a camera, temperature sensor, and a heart rate biosensor for its top-end wireless earbuds.

Subsequent reports mentioned that those planned sensor-heavy upgrades may have been pushed. According to Gurman, the third-gen AirPods Pro 3 “might” still make an appearance at the Fall launch event in a few hours from now, armed with a heart rate sensor.

Separately, as I first reported two weeks ago, I am still expecting AirPods Pro 3 to arrive tomorrow with a heart rate monitor. Other features include improved design for better fit and revamped charging case. I don’t expect major audio/ANC improvements. https://t.co/z2RD68S6J5

This won’t be the first such adventure of its kind for Apple, nor is it the first name out there to attempt it. The Beats PowerBeats Pro earbuds already come equipped with a heart rate sensor. Sennheiser even put a heart rate and temperature sensor on the Momentum Sport earbuds.

Gurman goes on to claim that the AirPods Pro will offer “improved design for better fit and revamped charging case.” Rumors suggest that the revamped charging case means the round physical button is gone, and replaced with a hidden capacitive button, akin to the AirPods 4. However, he suggests that any improvements to the noise cancellation and audio quality aren’t expected.

The iPhone 17 Pro is going to be pretty cool

Moving over to the hotly anticipated iPhone 17 Pro, he wrote in another social media post that a vapor chamber will be a big draw for the upcoming phones. Moreover, he also predicts two bold new colors — blue and orange — for the flagships.

So far, Apple has relied on traditional graphite sheets and a bonded aluminum substructure with the Titanium chassis on the iPhone 16 Pro to handle heat.

I expect the new heat management system/vapor chamber on the iPhone 17 Pro and Pro Max to be a key point tomorrow. That, of course, in addition to the external design changes, new orange and blue colors, and major camera upgrades (48MP across lenses, improved optical zoom). pic.twitter.com/FUEBF9P5Nq

This approach, however, is not nearly as effective as a bunch of high-end Android phones like the OnePlus 13, which come with a vapor chamber cooling system and run noticeably cooler under stress. It’s not just about the heat on the user’s skin. Poor thermals also take a toll on the sustained performance under load, such as gaming and hi-res camera capture.

On devices such as the Red Magic Astra tablet, a next-gen dual-sided vapor chamber cooling system delivered unprecedented stability, even under ray-traced workloads. I am extremely excited for similar performance-related gains on the iPhone 17 Pro pair.

Radiant Monitor 2 takes a sunlit approach to solve the glare and power problem

For most laptop displays, sunlight is the main antagonist. The brighter the day, the harder they work, and the more you start hunting for some shade. The Radiant Monitor 2 takes a different approach. Eazeye’s new portable monitor uses a 15.6-inch transflective LCD, which means it can use ambient light to improve visibility instead of fighting it entirely with a backlight.

In bright conditions, the backlight can be turned off, dropping power consumption to around 3W. Sunlight becomes part of the display system rather than the thing ruining your screen.

The Accentum Clip could make open-ear earbuds more appealing to music lovers
Sennheiser's new open-ear earbuds promise stronger bass without blocking the outside world
Adult, Female, Person

Open-ear earbuds have become one of the fastest-growing categories in personal audio. They offer a comfortable fit and let users stay aware of their surroundings, making them ideal for commuting, exercising, or working in shared spaces. The trade-off has usually been sound quality. Without creating a seal inside the ear, open-ear designs typically struggle to deliver the bass and immersion many listeners expect from traditional earbuds.

Sennheiser says the Accentum Clip is designed to address that challenge. These clip-style earbuds are advertised to deliver stronger bass, clear vocals, and balanced treble.

After six years of waiting, Google has finally released a new smart speaker. The $99 Google Home Speaker is available for pre-order starting today and hits shelves on June 25, 2026. At the core of the speaker is Google's conversational AI assistant: Gemini.
