Gemini for 12 hour shift?

[ECA77]

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

If you really wantbthe longest lasting buds and don't need super-duper ANC, then I can recommendthe M&D MW08. The sound is very good (not the loudest) and they have 10 hours per charge, with an extra 3 charges in the case. They are built like something you will pass down to your kids and they to theirs. The most beautiful ceramic top layer. The stainless steel case is built like a vault. 
Unfortunately, the ANC was very importantto me and aftrr tryingthe Gemini I was spoiled and am willing to take a hit on the battery life for the great Noise canceling.
