So, I can say that the company is responsive and stands behind the product. They do a great job for noise cancelling but are not very comfortable. Something thats cool about them is that docking them in their case automatically turns them off and taking them out automatically turns them on, so you do not need to remember to turn them off and on every time you use them. 5 and ordered a 9 and these fit great! Very happy with this product! Everything was a bit loose, but the bust fit fine. The noise canceling is pretty decent. Ive tried 2 pairs of wireless earbuds before but I found it a hassle to keep them charged so I always just gravitated back to my wired over-ear headphones. I like the story and the information shared is invaluable to me but the man vibe is huge. I got the teal-colored ones and they’re stunning.
