Rolling Square, known for its high quality and unique Apple-related accessories, has just announced its new HYPHEN Aria air-conduction headphones. These headphones claim to be “the biological way of listening with sound quality in mind.” I was a bit skeptical about what this meant when I first saw that tagline. I had tried bone conduction headphone tech in the past, and I was not a massive fan of those products. But this new take on air-conduction headphones left me pleasantly surprised.
