Gemini for 12 hour shift?

[Pim]

Guys,

I work from home on 12 hour shifts. Once in a while I have to be both on the phone and type at the same time so it's easier with head phones. I've been using B&W Bluetooth headphones but something is wrong with the microphones so I'm looking for a replacement. 

I read on the Devialet site that the Gemini's have a standard charge for 6 hours and 24 hours 'in the can'. Is anyone using them for a full day at work? I'm sort of thinking that I won't have them on all the time but they do need to be ready and charged when I get a phone call. Having to charge them because they're totally dead is not an option. When I wear them I will also be listening to music.

How easy is it to charge them? There seem to have been some issues 'in the past'?

Another question that I can probably find the answer for but can't be bothered looking up; can it be connected to two devices at the same time?

Thanks in advance,

Pim
