They fit perfectly and feel even better. No discomfort over my ears, or on my head. All shapes are different, but I can attest that a very round at the middle shape still works with these. After I started using this splitter, people had trouble hearing me, and I had to resort to using the mic input on my webcam because at least with that one, they could hear what I was saying. la vdd , aunque no lo parezca es muy resistente mi esposa lo usa en su cabina y le han puesto 3 o 4 bolsas de dama , y algunas parecen que le meten piedras , abrigos etc y no se a caído ni doblado ni nada lo recomiendo aparte que los acabados lo hacen muy elegante, recomendado para el hogar o negocio Stay out of the wet weather and I would recommend this product. Ill only buy from Mephisto. I wear them out, toss them guilt free, and go pull out another pair from my stash. The wrenches are worthless. I got some of the most well reviewed ones, some not so much.
