These headphones are great! I purchased them because the neighbor had a loud, barking dog. The headphone noise cancellation in combination with relaxation sounds helped me immensely with falling asleep. Headphones are designed so that you barely feel them as you're falling asleep. Battery life did not meet the advertised time so I'm not able to use these through the entire night.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
