Wearables

There are knives, good knives, great knives, and classic knives. Then there are the knives that are flat-out legends with remarkable stories behind them. One of these is the instantly recognizable Puma White Hunter that redefined the hunting knife.

Following up on the 50th anniversary ring watch Casio introduced last year, the new G-Shock Nano adds a beefier build with 200-m water resistance, shock resistance and a working mini-strap. This one is truly a G-Shock shrunken down to finger size.

Scientists have developed a fully transparent skin sensor that accurately measures UV radiation, detecting light and converting it to electrical signals. So before the sun's rays reach damaging levels, a phone alert lets users know it's time to cover up.

A couple of year's back, audio gear brand Creative was the first company to pop solid-state speaker technology from xMEMS in a pair of wireless earphones. Now the company has added sound personalization to the mix.

The new Meta Ray-Ban Display smart glasses look like a regular ol' pair of shades, but they show you a floating screen with useful content. That's already pretty neat, but I'm honestly more excited about the companion wristband they ship with.

A UK-based company believes it's got a better way to drown out noises and help you get a good night's sleep. Somni says its new sleep earbuds are the smallest ones you'll find anywhere, and don't ever need to be charged.

Audio gear maker Cambridge Audio launched a pair of wireless ANC headphones last year that hated being plugged into a wall outlet for a recharge. Now the company has refined the sound, improved on the long-haul comfort and introduced a new colorway.

Meta researchers have developed a wristband that translates your hand gestures into commands to easily interact with a computer, including moving a cursor, and even transcribing your handwriting in the air into text.

Much like the low-fluid warning light in a car, a new wearable sensor linked to a smartphone app is set to alert people when their hydration levels are dangerously low. The device could be a big help to athletes, first responders, and many others.

Boutique audio brand Astell&Kern is known for pushing the music hardware envelope in terms of tech and price, but its titanium-housed Luna earphones bump things up a notch with a price tag so high it will send your bank balance into orbit.

When we tried the first true wireless earbuds almost 10 years ago, battery life for continuous listening came in at around 2 hours. The latest buds from Soundcore last for 12 hours, or 192 hours with a charging case that could also juice up your phone.

It certainly sounds like something from a new sci-fi series, but a power-free set of contact lenses impregnated with nanoparticles has proven successful in allowing humans to see what has previously been invisible – even when their eyes are closed.

If you're gonna be inserting an object into one of your orifices anyways, why not have it check up on you while it's in there? That's exactly what the OpenEarable 2.0 earphones do, using integrated sensors to measure over 30 physiological parameters.

While headphones do provide an immersive listening experience, music is made to be heard through a good set of speakers in a room. Movengine's AirCore OWH headphones are made to simulate that experience, and I recently got to give the things a try.

We've seen a bunch of wacky mouse-on-a-ring ideas over the years, but this new device that's currently crowdfunding on Kickstarter takes a more straightforward approach, and it looks like something you might actually use.
