It’s that time of year again, when the warmth fades from the air and the landscape turns to a barren white wasteland. Okay, we don’t get so much snow in Texas. But even here you can walk around without fear of spontaneous combustion, so we’re all in the holiday mood. When you’re out and about in the cold, your normal headphones likely won’t do much to protect your ears from the elements. Lucky for tech enthusiasts, a company called 180s has products that will keep your ears both warm and entertained. 180s makes Bluetooth ear warmers (ear muffs) and several styles of wired ear warmers. Having used a couple of pairs over the last few weeks, it has become tough to brave the falling temperatures without them.
