There is a thermal sensor in these headphones that deliberately shuts them down when that sensor hits 0˚C[br]

If the headset shuts down in warm weather with a significant charge, that’s evidence of a separate problem
I’ve got a collection of Beats headphones that Apple has given me for free (I would never buy them) and they all have exactly the same behaviour. Even a wind at +5˚C will shut them down if the humidity is high.[br]
It’s a common trait among wireless headsets to auto-shutdown in cold weather no matter the brand. Lithium polymer batteries truly do suck below zero.[br]

'''I think the real crime with the Beats Studio 3 headset is that they refuse to run off of the analogue audio cable if they lack a power source, since the headphone jack is actually line-level and any amplified signal is attenuated to line RMS.'''
