Seconded, I've owned both SR-60 and SR-80 headphones and love them. They are open-backed so would not work well for mowing, but they're fine if you're in a lab

Seconded, I've owned both SR-60 and SR-80 headphones and love them. They are open-backed so would not work well for mowing, but they're fine if you're in a lab or airport. I'd suggest earplugs over headphones for mowing, unless you're trying to lose your hearing (or have a really quiet mower). =)
