For those who like to walk, run, cycle and otherwise enjoy the outdoors while listening to music or podcasts instead of the incessant drone of noise that the urbanized part of the world brings with it, the Koar Kbone IPX6 Bluetooth Headset is both a boon and a bane.This pair of lightweight titanium headphones (with a built-in microphone, so you can use them with phone calls when necessary) will let you enjoy the audio of your choice in relative safety, without the attendant risk that you won't hear the screeching brakes of the truck that's bearing down you as you cross a busy intersection against the walk light. It will, in other words, let you listen to your favorite symphony with crystal clarity, but it will let you hear everything else too, from the pleasant conversation of a companion to the ear-piercing staccato of a jackhammer.
The Kbone does this through the well-established miracle of bone conduction audio, where sound is transmitted directly through your skull to your inner ear, thus bypassing your ear canals and leaving them open as channels for communication from the outside world. The bone-conduction technique has an unexpected side benefit: you won't have to clear waxy build-up off the ear cups. The titanium shell is sweat and water resistant, so you can use the Kbone while you run in the sun or walk in the rain.
The Kbone IPX6 is an attempt to resolve a very real modern dilemma: How do we reconcile our ever-increasing desire to have music wherever we go with our eternal need to stay in contact with the rest of humanity? It's a genuine problem because sound is our most important source of information about the things we can't see -- the cheerful greeting from across the street, the warning honk from the car horn. And yet so much of the audio information we receive during the day is not only meaningless but annoying. The Kbone attempts to superimpose meaning on the noise while not blocking out the signal.
I found the music fidelity surprisingly good, better than I expected, as if the sound was coming through my ears. The headset is easy to wear and use. Recommended.
The band around your neck doesn't adjust. I would not recommend it. I gave it to my daughter for her birthday because she runs. I would return it but it's past the 30 days.
