Oxnard, Calif. — Car speaker manufacturer Planet Audio is expanding into portable Bluetooth speakers with the launch of its new Lynx brand. Six models will make up the line initially.

The Lynx PA100B pocket-sized Bluetooth speaker features auto pairing, track and volume controls, a 3.5mm port, included aux-in and USB charging cables, LED indicator, and four hours of playback via lithium-ion battery. Suggested retail is $29.95; it will be available in May.

The PA200B speaker ($39.95, June) has a fold-out design and the same features as the PA100B, but it adds a built-in mic so the device can double as a speakerphone. The PA300B ($44.95, May) and PA400B (price not available) have same features as the PA200B but have different designs.

The PA500B adds an AC adapter (price not available), while the PA600B ($79.95, June) has a splash-resistant design and adds a MicroSD slot, bike clip and a carrying bag. It also ups the playback time to five hours.
