Hello everyone. This is 52audio. Today we gonna teardown a TWS headphone, which is the
Huaqiang North Pro 5s. In the past, we have torn down many models produced by Huaqiang
North, but this one is very special. Let me guide you to unbox it to see.
First of all, this cable is definitely fake. But compared to the AirPods Pro charging case,
this case is literality a lot smaller.
Then take out the headphones.
This is actually smaller, you know, just like cut in the middle.
Let’s make the comparison by putting the
AirPods, AirPods Pro, and this tiny thing together. You will understand.
Finally, let’s see the weight. The overall weight is about 30g.
But one single headphone is only 2.7g.
Basically, it’s the lightest headphones we have experienced, and very comfortable to wear.
Try to connect it with the phone, and the headphone does not have a pop-up animation.
The touch area is located at the top of the headphone. But it will easily have accidental
touch when you pick it up and place it back, cause the headphone is too small.
As for music experience, not very good, but, you know, just OK.
There is no obvious current sound, noise and other problems.
Three sound effects can be switched by long press, including POP, HiFi and bass enhancement.
Honestly, the listening experience to POP and HiFi is almost the same, the bass enhancement
performance is not very good, but the highs and lows vocals are still relatively clear.
Bass enhancement-mode will improve the sound slightly, but it will be hard to listen to the lyrics.
OK, let’s just tear it down. Pry along the seam, use a little force to push it, and open
the charging case. The battery is in the middle, and the motherboard is under it; there are
two screws on both sides to fix. Remove the screws and remove the motherboard.
Firstly, it’s the battery. Its capacity is 370 mAh, with a small protection plate.
The small PCB of the indicator light is fixed separately in this corner.
Look at the PCB; this side is smooth, the other side is the charging female interface.
And an unmarked charging IC next to it,
and this is the unmarked MCU
Then, let’s tear down the headphones. Forcedly to press, and then gently pry it.
The two headphones have the same structure, including the speaker unit, battery, PCB.
Firstly, let’s look at the battery. There is no information on it; even the protection IC is the same.
The PCB is also very simple; the largest part is JieLi’s Bluetooth master control chip;
this one is ceramic antenna used to transmit the signal.
On the other side, we can see a silicon microphone used to talk.
On the side, we can see the yellow charging contact.
The headphones haven’t too much complicated stuff, very simple.
So, we can say that these headphones’ appearance is “borrowed” from the AirPods, AirPods Pro,
but the overall size is very small. Its biggest advantage is the comfort of wearing,
but it’s still wired to see the half handle. We can use it to listen to music, but it hasn’t
any other features. The internal structure design is very simple. Except for the JieLi’s
master control chip, other important chips are unmarked.
That's all for today's teardown.
