My Studio 3 headphones shut off in hot and cold temperatures. I got them this past Christmas, and they shut off everytime I go out to shovel the snow in my driveway up here in Toronto, Canada, under both a toque and hood. I thought this only applied in cold weather, but What's worse, is that my wife and I recently took a trip to Hawaii. And while we were sitting on the beach with the sun bearing down on us, my beats headphones did it again. They cut out after being on the beach only 30-45 minutes, and wouldn't let me turn them on or off. When we got back to the hotel room, and let them cool down, the battery still had plenty of charge, and they started working again. This is just ridiculous! These headphones are such a waste of money!
