I have N700 earphones purchased in late February in Heathrow.
I have been using it in Mozambique, where I live and it has been working well until yesterday.
While jogging yesterday, I met some some friends and I just removed it from my head and rested it on my neck-shoudelrs for a while (aboutn15 minutes). When I left the friends I put it back it I was not working. It did power on but did not proceed with (re)connection with my (i)Phone. I tried to restart a couple times and it didn´t. The blue light would come on, blink and off. Before that the battery level was about 16 hours.
While at home I put it back to the computer to charge it (blue light was flashing) and after a couple of minutes (15-20) when I picked it to test it, I noticed that the charging port area was hot (more than usual) and I stopped trying anything else. On teh day before I charged it on my internet modem usb port, as I did for days earlier.
I tried to reach both the shop and boss in UK with no success, eventually due to the current lockdown.
Please assist on what could be the proble and possible troubleshooting or if I just have to wait for the time to send it back for repair.
