My beautiful colleague is crazy, it's okay to buy this strange bluetooth headset, and when I buy it, I don't ask what brand, model, suggestion, cost performance, etc., I don't show the name, there are too many OEM.
The fault is not charging, the charging is not normal, in short, it cannot be used, use a spudger to pry the internal organs of the equipment and come out, look at the workmanship is also average, this aluminum foil sticker seems to be useless, because it is not effective if you do not connect the negative electrode.
The battery of the charging case can actually be made bigger and last longer, so you have to save that or something.
Binaural headphones workmanship, average, not very amazing feeling
The headphone unit, the yellow one is the battery.。。
It took two days to toss for a long time, re-soldering, repairing the circuit board, etc
I found out by chance that if I remove the circuit of the indicator light, Bluetooth seems to be usable again
After multiple tests, it was found that this strange component should be a magnetic Hall short circuit, so a scissor went down to disconnect the end Hall element
The whole kit is fine.
In the end, after testing, the existence of this hall seems to be meaningless, but its damage caused the entire kit to be unusable, and it is also possible that it is responsible for detecting the opening of the upper cover, but there is no magnet near where it is located, which means that it may be used to equip the high-end version, but this version is not used.
After that, after using it for a few days without any abnormalities, it was returned to the colleague.
