I worried. In addition to this, I wore this headset for multiple hours, and my eyes were starting to hurt more than my ears were! I wanted a tiny heel with a pointed toe for dress up, as my current heels now cause me foot pain and are not usable. Kid loves them! Highly recommend for your B & O headphones H8i and 9. PS: make sure your partner knows that these are noise cancellation earphones They are so cushy and comfortable. What I liked the most is the time in which the headphones are connected because I had one and had to press several buttons at the same time but with these the problem is solved, they also sound very good and the touch part to stop the songs I love . Muy linda y flexibles. I use Consumer Cellular and they couldnt help me since it is not a commonly used phone.
