NEW YORK — Beats Electronics’ colorful, oversized headphones serve as a fashion accessory to cool kids riding the New York City subway, but as tech companies such as Apple, Samsung and others are discovering, wearable gadgets like smartwatches and Google Glass still have a long way to go to become trendy.

Apple’s $3 billion purchase of Beats Electronics, by far the company’s largest acquisition, is at least in part recognition that Beats founders Dr. Dre and Jimmy Iovine might help Apple incorporate more style and flair into its premium technology gadgets — especially a coming wave of wearable devices.

Technology companies see wearables as an important area of growth beyond smartphones and tablets, and many are slowly realizing that if they expect people to wear gadgets — be they bracelets to monitor fitness activity, smartwatches to substitute smartphones or Internet-connected goggles — those devices must focus as much on form as function.

So far, the most noteworthy wearables have hardly been stylish. Google Glass looks more like something out of Star Trek than a fashion accessory. Fitness bands meant to be worn 24 hours a day are difficult to match with evening gowns or even a suit and tie.

“I guess they are accessories, but I would not say they are high fashion,” says Alison Minton, a blogger who writes on “There’s a ways to go before they could be considered high fashion in the way Chanel would be, or Prada.”

To change that, tech companies are beginning to attract top talent from the world of fashion. Apple’s move comes less than a year after the iPhone and iPad inventor hired Angela Ahrendts, who helped mold Burberry into the popular luxury brand it is today.

In recent weeks, Google lured fashion and marketing executive Ivy Ross, who’s worked for Calvin Klein, the Gap and Coach, to head its Google Glass unit.

For Ahrendts, Apple is already a luxury brand. Three years before she was hired at Apple last fall, she signaled her admiration for Apple in an interview with The Wall Street Journal.

“I don’t look at Gucci or Chanel or anyone,” Ahrendts told the newspaper in 2010. “If I look to any company as a model, it’s Apple. They’re a brilliant design company working to create a lifestyle, and that’s the way I see us.”

To be sure, Apple has long been a trendsetter when it comes to elegant gadgets. Jony Ive, who designed the iPod, iPhone, iPad and Apple’s newest mobile software system iOS7, still serves as the company’s chief style visionary.

But Dr. Dre and Iovine have created wildly popular headphones that young hipsters, celebrities and professional athletes adorn themselves with — even when they’re not listening to music. Dre and Iovine’s input will be highly valued as Apple looks to introduce its next breakthrough device.

The cultural coming-together of geeks and fashionistas is happening slowly, says Michael Londrigan, dean of academic affairs at LIM College, a fashion school in New York City. Apple’s hiring of Ahrendts, he adds, “was really the start of it.”

“Overall, the goal is to marry the function with the fashion, creating a wearable technology that is sort of seamless.”

Indeed, the bulky nature of many wearable gadgets is what stops many people from considering them, says Minton. To her, fitness bands are reminiscent of “gigantic, oversized watches they had when I was a kid.” The ones with the calculator built in.

“It doesn’t look like something an adult would really wear. It’s functional, but when you care about fashion it’s not always about function, it’s more about the look,” she says.

Besides the need for sleek, unobtrusive design that can be worn with a T-shirt as well as with a three-piece suit, wearable technology also faces a material challenge.

“Fitness bands are basically rubber. That’s hard to appeal to fashionistas,” Minton says.

So what’s going to nudge tech companies further into the fashion world? Minton suggests partnering with well-known fashion houses such as Stella McCartney or, yes, Burberry, on limited-edition collections.

“You may not need a fitness band, but if it is in Burberry plaid, you would wear it,” she says. Especially if only 1,000 are made.
