How important is NTC for LiPo batteries?

I need to replace my Bluetooth headphone LiPo battery.

ANSWERS:

@gizatm personally I would not. NTC is what can keep your battery from overcharging etc. I am not sure if your charger etc. would recognize when to stop charging etc. It might work temporarily but I'd be a little leery and would try to find one that gives me that extra little bit of protection.
