How to Wear Noise-Cancelling Headphones Outside

I strongly believe if you wear noise cancelling headphones outside, it is just a matter of time until you get hit by a vehicle. The Jbird X2 Bluetooth headphones are fantastic. They're super small in ear Bluetooth headphones. But even with one head, with only one ear covered, I still don't recommend it. You just don't realize how effective they are at making things sound way further away than they are,. not even noticing stuff.
