I need *two* different recommendations:
One for a reasonably high fidelity stereo headset ("over the ears") (not interested in "paying for a name", though)
The other, a "low cost" unit -- the sort of thing you wouldn't be too upset to misplace, damage, etc. ... "consumable"
Both need decent run-times (ideally 10+ hours) though they can have replaceable vs. rechargeable batteries.
