It does not have vibration or a long range, so if it is more than 1 meter away, you cannot hear it better than the f 990 of the same brand that I had but lost

I have had it since last summer and I have not encountered any problem. I don't know why there are so many bad reviews. The issue is not the value of a product in relation to its quality, but how you use it

The most useless thing I have bought... I have to constantly have my phone on me for the other person to be able to hear me and for me to hear them... If they move away from the phone even just 1 meter, the person I'm talking to hears waves..
Waste of money..

I have it for about 6 months. It is durable, its battery still holds up even when I leave it for days without charging, without it shutting down, it interrupts the conversation, my interlocutor cannot hear me and thinks the line has been disconnected. Other than that, it works perfectly!
Also, you can only listen to music through the internet and not from the pre-installed radio application on the mobile phone ...

Very bad choice. The product lasted for 1 month. It quickly had a problem with the wheel that collects the headset. Then it had a problem with the language. In the end, there was no sound, probably a problem with the cable. Very poor quality, only 1 month of life.

Terrible, they don't listen to me... Overall, this style is whatever you want it to be.. I've had some good experiences with them.. Now I fell into the scam

The smallest range I have encountered in Bluetooth. Additionally, when I move away from the device, the person I am talking to cannot hear me (while I can still hear them). I need to return to speak from the device for a few seconds and then send the sound back to the headset. Inconvenient..
It transfers sound from multimedia.
Finally, after the first month of use, the language in which it "announces its status, e.g. connected, disconnected, low battery.." changed from English to some undefined language, I imagine Chinese.
I would only recommend it for use in the car.
