5 is too big. He also has allergies to a lot of lotions/washes. But if you decide to do it anyway, just remember its $75 to replace one of your airpods after it flies out of the case and gets run over by a car while you scream. A lot of great reviews about this product. A+ all around. It is a great one piece bar! not an audiophile but double wow. Good quality, serves its purpose flawlessly, protects Beats (with cord) very well. I LOVE this wine rack. I wouldnt risk buying a size 9 for her that might be too big.
