Hi Alex. I've just received the Plantronics Audio 995 headset I was mentioning to you on the list. Contrary to my understanding, you can't use the headset whilst it is charging however I am told by Plantronics that the charge required is only 2.5 hours for active use of up to 8 hours audio and 6 hours with voice and audio combination. I hope this helps you decide which headphones or headset to go for. All the best, Ibrahim.
