Definitely recommend these headphones! They are so effective in keeping out disturbances at night, I am able to go to bed super early and not be disturbed by my housemates. I love the music they have on the app, it is so relaxing. There are some great guided programs as well. I go to sleep so fast when I have them on. I also wear them when I get headaches/migraines to soften the noise around me. You definitely need to give it a few weeks of wearing them to bed as they can be a bit uncomfortable at first and your ears can get sore when the headphones move in the night. I find it really helpful to wear the eye mask over the top which holds them in place and also sends me to sleep faster, keeping the light out as well. I will note that the sleep tracking has not been completely accurate for me, but customer service have advised that it becomes more accurate with time. Overall definitely worth the purchase!
Bottom Line: Yes, I would recommend this to a friend
