Jawbone, maker of the Up family of wrist-worn fitness trackers and the Jambox line of wireless speakers, is cutting about 15 percent of its staff, its latest round of layoffs this year.

As part of the reorganization, which involves about 60 positions, the San Francisco-based company will shutter its New York office and shrink its Bay Area locations. The move also affects offices in other countries.

"We are sad to see colleagues go, but we know that these changes, while difficult for those impacted, will set us up for even greater success," the company said in a statement.

Jawbone also laid off workers in June, with, according to The Information, about 20 positions affected.

The company, which recently refreshed its Up2 fitness tracker while adding sleep tracking to all its current models, is facing heavy competition in the wearable market from devices such as the Fitbit, the Microsoft Band and the Apple Watch. Jawbone last month won an injunction against Fitbit, in which a San Francisco judge ordered the competitor to return confidential information brought over by five of Jawbone's former employees.

This latest round of layoffs was first reported by TechCrunch.
