LAS VEGAS — Hearing aids aren’t sexy, so a lot of journalists here at International CES breezed right by ReSound’s booth.

The Danish company has been in the hearing aid business for 75 years, and launched the first iPhone-connected hearing aid at CES last year. Now the company is a back with a full lineup of iPhone-compatible LiNX hearing aids. The devices address the whole range of hearing loss, from the mild to severe.

As I approach 50, I’m wondering if I need a pair myself, so I went to check them out. I was impressed. Connecting a hearing aid to an iPhone adds a lot of very useful functionality.

LAS VEGAS — Of all the amazing technology on show here at International CES, the most surprising so far is Hewlett-Packard’s weird Sprout, a multitalented Franken-puter that looks like a ton of fun.

The HP Sprout is a touchscreen computer married to a multitouch pad, with a projector/camera/3-D scanner peering overhead. It looks like a bad prop from a Lego version of War of the Worlds.

I’d seen the press releases when it launched last October and had pretty low expectations. It just looked too weird. But I was genuinely delighted to see it in action.

LAS VEGAS — Bryan Chaffin loves his Casper mattress.

“I don’t even know where to start,” effused the Mac Observer executive vice president. “It’s the most comfortable mattress I’ve ever slept on. It was dead-easy to set up. It’s just incredibly comfortable.”

Chaffin is a satisfied customer of Casper, a New York startup shaking up the tired old mattress industry. Casper is doing everything differently, from the design of its all-foam mattress to the way it sells and ships direct to customers.

LAS VEGAS — When Garmin launches a $600 smartwatch just a few weeks before Apple is about to introduce its category killer, the company must be pretty confident.

Here at International CES, Garmin is showing off its new line of Fenix 3 Sports Watches — multisport fitness trackers with built-in GPS that can pair with a smartphone to show various alerts and notifications. It comes in three models, including the handsome Sapphire, which has a hard sapphire crystal face. It’s a beauty, but surely doomed, right?

When asked if Garmin was worried about the Apple Watch, due to be launched sometime this spring, a spokeswoman confidently said absolutely not. She explained that Garmin’s watches are unapologetically outdoor fitness devices built for sportspeople who want a watch to do very specific things — track workouts – and aren’t interested in beaming heartbeats or sending emojis.

“They are purpose-built,” she said, gesturing at the display. “They’re built for hiking, biking and running. Garmin has been in the wearables market for 10 years. We’re not worried at all.”

LAS VEGAS — For eight years, Paul Chavand been working hard to bring the world a pair of motorized skates. Why? To revolutionize the simple act of walking. Chavand’s dream is turn a simple stroll into an effortless glide on motorized wheels.

But don’t call them skates. Chavand, a mathematics teacher from France’s Burgundy region, gets rather upset at that. Skates imply imbalance, falling over and wildly flailing arms. Chavand’s Rollkers require no “skating.” You just stand still and the motorized wheels zip you along. Balancing is as simple as standing up, the inventor says.

So instead of “skates,” he calls his invention, rather comically, “under shoes.”

The big question is why you’d want them.

LAS VEGAS — As soon as I saw this Wi-Fi-connected kettle, I wondered to myself: “Why on earth would anyone want a Wi-Fi-connected kettle?”

This is crazy. Connectivity gone mad. It’s got Wi-Fi for the sake of it. It’s a gimmick. Tech trying to solve a problem that doesn’t exist.

But I talked to the CEO, and his answer surprised me. Now I totally want one.

The Smarter Wi-Fi-connected kettle, called the iKettle in the U.K., is so British it’s not funny. Every household in the U.K. has an electric kettle. It’s on all day, every day, making cuppa after cuppa, all day long.

Apple won’t be at the mammoth International Consumer Electronics Show in Las Vegas next week, but once again, it’s setting the agenda from afar.

While Korean electronics giants like Samsung will dominate the show floor, Apple is laying the future path for the entire tech industry.

In the coming year, the tech industry’s big battlegrounds will be your body, your home and your car. At CES, thousands of companies will showing off new and prototype products to do battle in these arenas. But Apple is the company to beat. With the upcoming Apple Watch, in addition to HealthKit, HomeKit and CarPlay, Apple is setting the agenda for the entire tech industry, and it’s not even there.
