I have tile surrounding the stove, these are perfect, adhesion is reliable. I was able to be heard at a normal speaking voice. For 10. I got several compliments on them already too. I feel it scratches every time I try to put it on. I found that while the ML size fit better than Apple?s M or L sizes, that the adapter included was mediocre quality and did not fit very well, shifting and making clicking noises when in use. The remote paired with my Note 9 quickly and easily, spent the day playing with this, and all worked fine. Also, they seriously look like jail slippers. So I gave it to her. 5MM jacks.
