I use them almost daily for running, cycling, walking and climbing. My only gripe with them is the long neck bad, so I've had to stop myself from splurging on a Mini when it came out. :D
If you do any work in a noisy industrial or trade setting you owe it to yourself to get these.
I used to buy the 3M connect earmuffs but their connectivity is bad, the ear-cushions break down and the mini-usb charger port snaps off. I had to buy a new set of earmuffs once a year.
It’s crazy: shut the laptop and walk away to listen to a podcast on your phone and they just beep beep beep.
