Using headphones in cold weather causes them to shutdown completely.
My Solo wireless have been working great. I use them while walking my dog for 2-3 hrs per day and the charge last about 2 weeks. This was true until now! Since the weather has cooled off (in the 20s) my headset shuts down about an hour into the walk. I get a chime then nothing, no lights , sound nothing, I cannot turn them back on they are just dead! When I get home and let them warm up for an hour or so, I can turn them on and they show full charge! Must be the cold because I can use them inside without them shutting down. Is this normal?
