Query: THE WORST!

Absolutely awful sound! The earbuds have to be jammed deep into your ears (which hurts) to eliminate the tinny sound. And although there are three different size buds, none of them sit very well. This was a very unusual experience for me with a Sennheiser product. I have others and they're excellent. This particular item just happens to be a lemon.
