I have a cell headset that stores in a charging case. Such a brilliant balance in convenience and battery life. I have never once thought about whether the headset is charged. Same play Amazon did with the Kindle Oasis cover, and now Apple with these. You're going to want to keep the two parts in something, why not a charger case?

Your heavy battery hanging off ears comment is like people hearing about a Walkman asking how you'll fit LPs in your pockets anyway:

// PS. I highly recommend carrying an amp matched to drivers on your head. In particular, this set: http://blue-headphones.com/powered.php ... an ideal candidate to add a nice DAC to in a future model.
