Portable Bluetooth stereo speaker

The Monoprice 111427 is a compact audio device built for wireless streaming from phones, tablets or laptops. It integrates a 5-watt RMS amplifier per channel and enhanced bass output for clear playback in small rooms or outdoor settings. Digital volume control and a 3.5 mm wired input give flexible connection options.

Replaces single-driver phone speakers

The jump is worth it when you need stereo separation and louder output without mains power. Built-in Bluetooth profiles cover music streaming, call handling and remote control, so the unit works as a speakerphone as well as a music player. The integrated 5 VDC 1000 mA USB port lets you top up a phone while listening.

Fits in a backpack or desk bag

At roughly 11.8" x 3.1" x 3.2" it slides beside a laptop and leaves AC outlets free for other gear. The USB charging port reduces the number of wall adapters you carry. Wired 3.5 mm input keeps audio working even when Bluetooth is unavailable or disabled.
