This has to be the coolest set of speakers featured in Trickmaker website, this is absolutely phenomenal, it’s the future of speakers so without further ado, here’s presenting the Klang Ultrasonic. Designed under a project by Bang and Olufsen, this is still the prototype model. Here’s the deal: these speakers can beam music in any direction desired, which means that only you can listen to it. It’s like wearing headphones without wearing any. These speakers emit 30,000 Hz frequency inaudible to human ears, the ultrasonic waves are split into three, producing an audible wave encapsulated by two inaudible ones in such a way that your right ear can hear sound coming only from the right and left one only from the left speaker. Go ahead and listen to your Justin Bieber collection without anyone knowing.
