CozyPhones 4.0 review

CozyPhones takes a different shape from every other pick: instead of cups and a plastic band, flat speakers sit inside a lightweight fleece headband that can double as a sleep mask. That makes it the easiest option here for car seats, plane naps, bedtime stories and children who dislike pressure on their ears or refuse earbuds. Version 4.0 adds Bluetooth with up to 16 hours per charge, keeps a 3.5 mm cable with play and volume controls and a microphone, and introduces Share Mode to link two headsets to one tablet. It ships in Kids Mode, which CozyPhones describes as volume limited by default, and a Normal Mode raises the volume for planes and road trips. The company does not publish a decibel figure for either mode, which makes the cap hard to compare. Take the electronics out and the headband goes in the washing machine. It costs $29.99 with free US shipping and 30-day returns.
