Bluetooth wireless headset advice

Hello all,

I've already done mountains of research, but I'm looking for a headset for work.
I need it to connect to BOTH my computer (for audio) and my phone (bluetooth, for calls and whatnot)

In a dream world, sennheiser would make their Game Ones wireless+bluetooth.
I absolutely love the fit of senns.

So, throw any suggestions you have my way. I've been eyeing the Steelseries Siberia 840s.
They're pricey, and I prefer a more oval cup design.

I was eyeing these bad boys for awhile before making an all together different purchase.

Hmm... I hadn't seen those. Quite tempting.

Do you need a surface too?

That's quite tempting miller. IDK if I could swing the wife on it. I'd need the top tier one to do anything I'd want a surface for.
