I am not an audiophile, but these fit my small ears and didn't fall out. They were a great value for the money. I paid about 15 bucks for them on eBay not realizing I could have spent a bit more to secure the two-year warranty by buying on Amazon. The left bud just conked out one day. But overall, these were great.
