Query: for some ears only

The generally positive reviews about sound quality and fit spurred me to buy this product, and I found that they were much too loose for my ears. I'm happy with the sound quality and whatnot, but I've gained minimal utility from this purchase, perhaps because my ears are not of the standard size. If you suspect your ears are similarly non-typical, I suggest going with something else. I did give these to my boyfriend, who has lovely, and probably normally-sized ears, and he commends their quality.
