Jawbone is selling off pieces of its business, reports say

Jawbone has put its Jambox speaker business up for sale, according to a report Friday from Fortune magazine, which cites "multiple sources." The company wants to focus "exclusively on its health and wearables business," the magazine reported.

Later on Friday, Tech Insider -- also quoting unnamed sources -- reported that Jawbone had halted production of its Up fitness trackers and sold the remaining inventory at a discount to a reseller.

Tech Insider late Tuesday modified its description, saying the company "has slowed production" of the devices.

Jawbone had disputed Tech Insider's earlier characterization.

"The company did not halt production at any point," a company spokesman said in an interview Tuesday.

Jawbone, which has been struggling to compete against companies like Apple and Fitbit, laid off 15 percent of its global workforce last November. It has also been involved in a series of lawsuits against Fitbit, alleging that its rival stole trade secrets by poaching employees. In October, a San Francisco judge ordered five Fitbit employees to return confidential information they took before leaving Jawbone.

Earlier Tuesday, a Jawbone spokeswoman said in a statement the company has no intention of phasing out the Up line. "Each and every employee at Jawbone is currently focused on the design, development, marketing and production of either our current, or our next generation, Up wearables product line," she wrote.
