Israel’s Noveto has invented “sowlo” – the virtual headphone – that beams the sound from your device directly into your ears. Sowlo’s 3D sensors and algorithms find your face and a tiny speaker focuses the sound at your ears. No sound leaks out even when you move your head. My wife can’t believe this.
