I have always been fascinated by sound design and try to stay up to date with it whenever possible. I found this amazing 3D sound demonstration using a technique called binaural recording that creates an incredibly realistic spatial audio effect.

In this recording, a virtual barber chats with you and sets the scene for your haircut. Close your eyes (seriously, it makes a huge difference) and enjoy. You will actually feel like your hair is being cut.

• Put on headphones (speakers will not produce the effect)
• Close your eyes (trust me on this one)
• Press Play and let the barber do the rest
