These Panasonic RP-HC500 noise-cancelling headphones are pretty boss. So much so that I've composed an ad.

Are children and wild animals constantly making noise at you? To hell with them. They'll get theirs. Until then, chill them out with the RP-HC500. The headband adjusts so that you don't get a stupid crease in your head. The ears swivel 90° in case you are a rabbit. The power is supplied by one battery, which for some reason was never enough for any gadget until now. It's plenty. Stop making me use so many batteries. Make me use up the 80 AAA's that I've accumulated for no reason at all.
The bass is deep enough to listen to Boston, while the treble is high enough to listen to Boston, so everyone should be happy. A blue light comes on to let people know that you are on the moon. The noise cancellation is second only to actually being deaf. We even include an extra two-pronged gadget that no one can figure out what it does. It's better than Bose and it's way better than putting a bowl of water over your head, plus you can listen to music, although it probably costs more.
