First off I want to say as someone with bad ear fatigue and swollen ears from any earbuds that go in-ear this is legit the best thing to ever happen to me!! Now let me tell you why. First off sound quality, the sound quality is phenomenal but its not just ordinary sound. The sound is so hard to explain its like a movie theater is constantly following you around everywhere you go. Because its open and not inside your ear I feel like the sound is more natural and feels like you can touch the sound rather it being locked up in your head. I could go on all day long about the sound but lets talk about the comfort. As someone who can only use headphones because earbuds are so uncomfortable these really change the game. If you put these on right it fits perfectly and does not fall out. Ive worn these today for a total of 8 hours and a lot of the times I totally forgot they were even in. I tested them walking around the store doing some chores and even laying around and it didnt cause any problems. They are very lightweight so you dont have to worry about it weighing your ears down or falling down. Some more perks that are very nice to have are all the modes they offer I wont list them but the bose app offers different sound settings to choose from to enhance your experience. For the mic/phonecalls I don’t really know but I also don’t care. I give these a 5 star because of sound and comfort. I truly can’t explain how balanced and comfortable these earbuds are. Buy them and you will see😁
