Famed composer Ludwig van Beethoven lost his hearing over time, but because of that, he discovered a new way to “hear” his compositions: by using bone conduction.

Beethoven would bite his conductor’s wand and press it into his piano, turning audio waves into physical vibrations he could feel. Because of his discovery, we not only have classical works of art, but we’ve paved the way for bone-conduction technology to be something all music lovers can enjoy.

There are all sorts of cool headphones out there. Headsets feature Bluetooth, noise-cancellation, with designs that are over-ear, in-ear, wireless, water-poof, and so on. These headphones from FresheTech feature most of those features, plus one you don’t see very often: bone conduction.

With all our devices, it seems like there are nearly as many ways to listen to sounds as there are sounds themselves. That’s why we’ve gathered up these deals on four of the best ways to enjoy your tunes, shows, podcasts or anything else that tickles your ears.

In this Cult of Mac Deals roundup, we’ve got top-shelf on-ear headphones, nearly invisible in-ear buds, a set of workout-ready Bluetooth earbuds and a headset that transmits sound through bone conduction (seriously).

Imagine walking around listening to your music without buds blocking your ears, keeping you present and aware in the place you’re standing. That’s exactly what bone-conduction headphones offer, like this Bluetooth-enabled set by KOAR. Instead of air, they use your skull as the medium to transmit sound to your earbuds for a one-of-a-kind listening experience. And right now, you can get a set for $76.99, almost half off.
