I had this happen a few nights ago when the battery died rather abruptly. I grabbed the cable that I had just used to charge my phone - Android, using the same type "C" connector - and plugged it into my new NCH700s. It immediately started blinking red/white. Thought it might be caused by a non-Bose cable, so grabbed the cable supplied with my headset, plugged it into the same charger and the headphones. It began to blink the same red/white for a few ticks then started blinking white (indicating it was charging). Left it charging 'till next morning and observed the LED was solid white (indicating fully charged). However, when powering up, the voice told me that battery was very low. So, plugged it back in and it blinked white going solid after about 30 minutes. Powered up, voice says I now have 20+ hours. It seems to be behaving normally, however I haven't tried to charge since then.
While I can't find anything that says the user must use the Bose supplied charging cable, you may want to try that if you haven't already.

I have the same problem of red/white LED blinking alternatively. I charged it with the official cable provided from Bose. I charged it with my computer for 2days before I had this symptom. What should I do?
