SAN FRANCISCO — SOL Republic added its third in-ear headphones last week, the Jax.

The Jax feature the company’s i2 Sound Engines (what the company calls its driver technology), and come with flat cables and in-line mic and controls. One version will support Apple devices while another is a single- button universal control without volume control for Android devices.

They are also part of SOL’s Ear Tips For Life program, which promises to replace the silicon ear tips any time they are lost.

Black, white and blue versions are currently available for a $39.99 suggested retail. More than 15 colors are planned for the rest of the year, SOL said.
