Ive owned the XL-1's. I also owned Romer II's. I HATED...HATED teh xl-1s. when I had them 3years ago and 50 some odd pounds lighter, i had a thin face and they would always fall off, however, the Romer II's stayed on nicely.. you can always add some 3m Rubber adhesive grip to the part near the ears. I did that and it helped alot.
