At first glance, a Bluetooth headset from China is somewhat similar to headphones from an Iphone, only slightly modified.

Headset control is standard, carried out with one single button. The principle of its operation is the same as that of any Bluetooth headset (on and off, answer-reject a call, dial the last number).

The headphone has a charging input and a small microphone well. There is also an LED that is responsible for indicating the power on and pairing the device with a smartphone.

Experience of use:

I tested a Bluetooth headset from China for a couple of days. During this time, the device was discharged a couple of times. The earphone holds perfectly in the ear, for two days it never fell out. The declared technical characteristics do not correspond to reality. For example, a headset in conversation plus listening to music sits down in 2-3 hours, but what pleased me is the range. Within a radius of 10 meters, the signal is received steadily without loss of quality. Communication on the phone is reproduced clearly and the interlocutor also hears me well, the only thing is to speak a little louder, since the microphone is in the ear.

In short, the earpiece, as I wrote above, is practically invisible in the ear, especially if it is flesh-colored, so this device can be useful for students and schoolchildren. Remember how in the movie Operation Y and Shurik's New Adventures - The beauty's heart is prone to treason and change ... One, two, three, I give a sample.
Kostya, as you hear? Three, two, one, welcome!
- Hello, professor.

And for girls-students with long hair it is generally "JACK-POT". In general, she learns better, knowledge is never superfluous.

Main advantages:
compactness;
excellent workmanship;
price

The main disadvantages:
the sound quality is C grade
the operating time is less than the stated

Sentence:
In short, this s530 bluetooth earphone from China does its job well, the sound quality for listening to music is disgusting but quite decent for talking. Who appreciates compactness and does not like when two wires hang from their ears, you can take it. Well, for schoolchildren and students, this is a magic wand.
