Portable 2.2 speaker for phones and laptops

The FOSA fosa56zds1t4kw-02 is a compact stereo speaker with a 2.2 channel layout and a retractable resonance chamber for enhanced bass. It connects via a 3.5 mm aux jack to smartphones, MP3 players or laptops. Weighing 0.07 kg, it is built for travel and desktop use.

Passive cooling with battery runtime

The speaker runs on a built-in 180 mAh battery that delivers about 1.5 hours at maximum volume or up to 50 hours at low volume. With no fan or moving parts, operation is silent. Power is drawn only during USB charging, so normal playback adds no load to the source device.

Retractable chamber and integrated cables

The expandable resonance chamber extends to boost low frequencies and collapses for storage. A 3.5 mm audio cable is stored on the bottom of the unit and a USB charging cable is included. The 3.5 mm woofer size and 89 dB signal-to-noise ratio reflect the driver specifications.

Questions about this item

How do I connect the 3.5 mm aux cable to my laptop and what step do people miss?

Plug the attached 3.5 mm audio cable into the laptop headphone jack and the speaker; the step people miss is pressing the power button on the speaker after connecting the cable.

What part will need replacement first and when?

The built-in 180 mAh battery will degrade over time and is not user-replaceable, so the whole speaker will need replacement once runtime drops below your needs.

What limit appears first during continuous playback at maximum volume?

Battery life is the first limit, giving about an hour and a half of playback at full volume before the speaker shuts down.
