Unlike a walkie-talkie, it's unobtrusive and hands-free; clip the magnetic mount onto your clothes or strap it onto a body part and you're good to go. Beyond the convenience, the device harnesses technology to improve sound quality, which is often less than ideal when outdoors. Milo integrates six high-performance digital microphones and a powerful speaker so you can be heard clearly and hear everyone in your group, even in noisy outdoor environments: sophisticated audio signal processing algorithms suppress wind and other background noise. Furthermore, for those of us who have experienced hearing loss, Milo can be paired with a conventional Bluetooth speaker for getting that voice right into your ear.
