Hi, I bought the FreeTalk headset a month ago and now it's behaving very strangely. Sometimes I can't turn it on, each time I press the button it turns itself off after 5 seconds.

And it doesn't help with plugging in the loading cable. It still turns itself off after 5 seconds.

After a lot of connecting and disconnecting the dongle(?) and the cable I get it to work. But this happens like every second day.

What's wrong and what should I do?
