Noise cancelation for kids? Doesn’t that mean they’ll ignore their parents even more often than they already do? Perhaps, but it’s a risk worth taking if it means your kids’ hearing will be protected over the long-term. That’s exactly the premise behind the Puro PuroQuiet headphones. Not only are they wireless and great-sounding, but they also come equipped with a software limiter that keeps the volume at or below 85dB, which is considered the maximum volume that children should be exposed to for prolonged periods. The noise-canceling feature means they’ll actually be able to listen to lower (therefore safer) volumes.
In terms of juice, the Elite 65t offer 5 hours of battery life — matching the AirPods — and the included charging case adds two refills on the go. Jabra also matches many of the best features we’ve seen elsewhere in the fully wireless space, with the company’s Sound+ app that lets you adjust settings like equalization, or whether you want to use your phone’s built-in smart assistant (Siri on iOS, Google Assistant on Android) or Amazon Alexa. Sensors built into the headphones can be set to play and pause music when you remove the buds, and they can even be set to pipe in different levels of ambient sound, which is great for hearing announcements on the plane or your office mate.
In early powered radios, the headphone was part of the vacuum tube's plate circuit and carried dangerous voltages. It was normally connected directly to the positive high voltage battery terminal, and the other battery terminal was securely grounded. The use of bare electrical connections meant that users could be shocked if they touched the bare headphone connections while adjusting an uncomfortable headset.
