You need to have the mobile phone in your hand because otherwise the connection is easily lost, it did not have a cable inside despite being mentioned in the description, the cushions detach easily

They are very nice headphones, it would just be even nicer if they could fold so that they fit better in the bag!!!

Very beautiful construction, with a matte texture and nice design. I just got them in my hands and the conclusions so far are:

(+++)
-Easy to use and connect.
-Clean and powerful sound.
-Beautiful.
-Lightweight.
-Fit well on the head.
-Very comfortable cushions.
-Good range (worked at a considerable distance and through 2 walls)
-Very good microphone (according to my conversation partner)
-Relatively low price (I got them for about 16 with shipping)
-Arrived very quickly (purchased through Scroutz)
-Noise suppression equivalent to its price.

(----)
-Relatively low-quality construction (the non-matte plastic on the inside is quite cheap, although it looks very good overall. The cushions rotate on their base and the top cushion can come off if pulled. I wouldn't call it sturdy, but time will tell.
-The matte easily shows fingerprints, although they are not very noticeable due to the color.
-The sound seems flat to me.
-Strong bass but nothing special in terms of quality or depth.
-Tight around the ear and relatively small (it is oval-shaped, so it doesn't fit my entire ear. After a while of use, my earlobes feel sore from the pressure. The fact that the cushions rotate helps a bit with comfort on the ear.)
-The package did not include a 3.5mm jack cable for wired connection.
-The bass is strong, to the point of becoming quite tiring after a while. It needs an equalizer.

Extras:
-The instructions are only in English and Chinese (it doesn't bother me, but not everyone knows these languages.)
-The instructions say "click to change the song, long press to adjust the volume," but in reality, they work the opposite of what it says, which is very positive from a practical standpoint.
-The battery was almost fully charged when they arrived for some strange reason.
-The button to increase the volume is below and the button to decrease it is above, which is annoying for me but not something terrible or unusual.
-Instead of hearing the ringing sound when someone calls, the phone rings normally and in the headphones, you hear a rrrrring-rrrrring, a classic ringing sound.

I will upload photos later if it allows me.
Overall evaluation: Slightly better quality than Tiger headphones, for those who know, but beautiful and wireless. The headphones I have have a richer sound, to be honest.

Hesitant value for money.
