A couple of years ago, I bought some Shure, inner-ear headphones that I am very satisfied with for presenting crystal clear sound. The trick is that they have to fit just right into your ear or you lose a lot of bass. Some people do not like the sensation of squishing something into your outer ear canal but if you can get used to it, this also makes them excellent as doubling as ear protection (with the added bonus of music) when you cut the grass.

I think I payed $120 but I recall that being a very significant sale. Maybe even 50% off.

They are also great for airplanes. I don't use them at work because I feel too isolated.

With great power comes Awesome irresponsibility.
