AirPods Pro Deep Dive Teardown | Hifigo

As true wireless earbuds continue to evolve, companies are making them smaller and adding powerful features like active noise cancellation (ANC). We'd heard rumors about a refined design and ANC of AirPods Pro for months. Finally they quietly revealed in a press release on a Monday afternoon. The Pro model introduces a host of new features, but that comes at a cost. And the question is: How is the AirPods Pro ($249)  built to worth the extra $50?  Let's check.

 1.Unpackage of Airpods Pro 

 The box with familiar smell and characters of Apple.

Product model Airpods Pro with Wireless charging case in 6 languages,  certifications and company information.

 The package seems a pro version as well, it is thicker than the previous version.

The included charging case is different with the previous one. While the previous versions (2.1 x 1.7 x 0.8 inches)look and open more like a floss container, this new one (2.4 x 1.7 x 0.9 inches)  is wider and shorter. The new case is noticeably larger, though not by much. It's still quite small, and it's more compact than similar cases from Jabra, Sony and so on. Other than size, that's where the changes to the case itself end.

Press relief vents. 

Take a look at the head of the AirPods Pro, which is larger than the previous buds and holds two black mic vents.  At the bottom is a slim glossy chrome circle. Toward the end of the bud that goes into your ear is a new and notable addition: a silicon eartip. 

Airpods pro deep dive teardown 20

The side that faces forward (towards your face) is flat, so you'll know where those controls reside when you reach for them.  At the top of the stem sits another vent, hiding another microphone. 

Airpods pro deep dive teardown 24

The company added a silicon tip that not only makes the AirPods Pro more comfortable but also gives them the seal needed for effective noise cancellation.  And the overall shape is now more of an oval instead of a circle. 

Airpods pro deep dive teardown 25

The stem is shorter than on previous versions of the AirPods and now has a small notch cut into them. Give either a squeeze and you'll discover an embedded Force sensor.  The stick-like extension is still here, but it's shorter and houses a new "force sensor" for the on-board controls.  

For you fitness fanatics or heavy sweaters, the AirPods Pro are IPX4 rated.

  1. AirPods Pro have two microphones per earbud. The one on the outside detects ambient sound to analyze your surroundings. The second faces towards your ear to pick up any remaining noise that sneaks through. Together, the mics work alongside "advanced software" to continuously monitor your environment and adjust the ANC accordingly. Apple says the setup "adapts" the audio "200 times per second" to keep things sounding their best.  Apple says this tech is unique, and it's the first to use the 10 audio cores on the H1 chip to make the adjustment in real time. The company also says that a key difference from other ANC headphones is, even when there's no music playing, the AirPods are still analyzing and adapting based on your environment. 
  2. Apple employs what it calls Adaptive EQ, which automatically tunes the low- and mid-range frequencies to each user's ear. There's also a built-in amplifier that Apple says enhances clarity while also optimizing battery life. It's a lot of techspeak, but the end result is much better audio quality than even the most recent AirPods can muster.
  3. Apple managed to squeeze three microphones and six sensors into the tiny, redesigned casing and still had room for its lauded H1 chip. They even added eartips.
