Apple Airpods Pro Disassembly: Repair? No Way.

On the evening of October 28, Apple released AirPods Pro directly on its official website, priced at 1,999 yuan in China and shipping on October 30. The AirPods Pro have been changed to an in-ear design and support active noise cancellation, pass-through mode, including headphones, charging case are “fatter than AirPods “The AirPods Pro have been changed to an in-ear design and support active noise cancellation, pass-through mode, including headphones, charging case are “fatter than AirPods ” The new design has also become the primary target of netizens’ spoof, such as AirPods Pro resembling the pea shooter in “Plants vs Zombies,” which is like a “co-branded model” after being PS. According to Apple, the noise cancellation feature works as follows: the headset’s outward-facing microphone detects external sound waves, and before the user hears them, AirPods Pro cancels them out with a comparable anti-noise wave, achieving noise cancellation. The inward-facing microphone detects excess sound waves in the ear and cancels them out with the same anti-noise waves.

To ensure sound quality, noise cancellation is continuously adjusted at a rate of 200 times per second. AirPods Pro includes a custom Apple H1 wireless chip (with 10 audio cores) in a System in Package (SiP) package designed to support Bluetooth 5, a strength sensor (to switch between controlling music, calls, active noise cancellation, and pass-through mode), and IPX4 water resistance.

Each AirPod Pro weighs about 5.4g, which is one-third more than its predecessor, and the charging case weighs 45.6g (the pairing button is on the back). Of course, this brings a longer battery life; according to Apple, using the charging case additional multiple charges to achieve more than 24 hours of listening time, word charging up to 4.5 hours of listening time, charging five minutes to listen to about 1 hour. What are the secrets hidden inside the fully upgraded AirPod Pro?

Before comparing the differences between AirPod Pro and AirPods, the replaceable silicone head, shorter and sturdier body, professional strength sensing, and bottom microphone grille design adjustment, it’s time to start disassembling and easily remove the first (and possibly only) replaceable component – the silicone earbuds. However, the AirPod Pro’s earbuds appear to be specially designed, which means they are incompatible with other earbuds, and official accessories may be your best option. After removing the silicone earbuds, the next disassembly essentially requires “destruction”: a heat gun and a warp can first separate the top protective case of the headphones, which is not an easy process.

After prying the case open a little more, iFixit was not surprised to find glue. After separating the top, you can see that there is a button battery inside, and then here you need to disconnect a cable to separate the two modules. The battery is removed from the protective case of the headset, which requires the glue around the battery to be slowly separated. The battery is connected by a soldered cable, making it difficult to replace.

According to iFixit, the AirPod Pro uses a lithium-ion coin cell battery, and the Samsung Galaxy Buds uses a battery made in Germany, but the Galaxy Buds battery is a little larger, model number CP1254, and the AirPod Pro battery model number is CP1154.

Regardless of the battery, you can see a small speaker inside the plastic bracket that holds the headphones, and after removing it, you can see a speaker inside the headphones (in-ear part), which is an important part of the AirPod Pro that supports an excellent noise-canceling experience. This coil is a “voice coil,” to be specific, which generates a magnetic field when an electric current is passed through it, creating “anti-sound waves” to cou

Despite iFixit’s efforts, this core chip was not accessible… The next step is to check the microphone under the headset, which can only be done by destroying the outer plastic case. Does this make sense? iFixit discovered through X-ray photos that there are still many components hidden here.

Following the destructive disassembly, iFixit obtained a long circuit “strip” at the lower end of the headset, as shown below: the red box is the microphone; the orange box is the antenna; the yellow box is the mysterious SiP package; and the green box iFixit speculates may be the latest strength sensor, on its working principle iFixit believes it may be through the capacitor to record finger tapping or through the tiny deformation sensor to feel the squeeze. This process also necessitates the use of a vise, but it appears that the charging case has not been permanently damaged thus far, and the charging case can then be “pulled up” from the top, as if it were a three-layer structure. According to iFixit, the design is user-friendly because it is latching on rather than glued.

On the charging case’s circuit board, you can see the following components: a red box for L476MGY6 A5; an orange box for Broadcom 59356A2KUBG wireless charging module; a yellow box for TI 97A4PQ1; and a green box for NXP 610A3B KN3308, which is most likely the charging IC. The first two of these modules are also used in the charging case of the second generation AirPods. The next step is to remove the battery inside the charging case, but iFixit discovered a device that looks a lot like a microphone between the two batteries.

The battery inside the charging case of AirPods Pro is two pieces connected together with a specification of 1.98Wh, which is higher than the capacity of the second generation AirPods.

Furthermore, iFixit points out that the Lightning port on the charging case is still modular, so if it is damaged, it can theoretically be replaced by the user. Finally, iFixit gave the AirPods Pro an unsurprising 0 out of 10 repairability score (the higher the score, the easier it is to fix). The AirPods Pro are apparently “impractical and uneconomical” to repair due to their non-modular, glued-together design and lack of replacement parts. iFixit believes that unless you work on the AirPods Pro production line, you will have a difficult time disassembling and repairing the AirPods Pro in good condition.
