They also have excellent noise reduction, blocking out most outside noise; however, I always advice potential users of this kind of project to remember that superior noise-blocking also brings with it less awareness of one's surrounding, especially important to keep in mind if you use them where you have traffic or otherwise have reason to stay alert while running or exercising

The max volume level on these is also quite a bit less than my other blue tooth earbuds, which makes sense since really cranking up the sound would defeat the intended ambient awareness
