Description

Overview

A pocket-sized external sound box that plugs into a standard 3.5 mm headphone jack and lifts audio out of a phone, tablet or laptop. It is a compact plug-in unit, supplied in black or white.

Specifications

  • Input: 3.5 mm audio jack
  • Form factor: portable, free-standing
  • Colours: black, white
  • Compatibility: any device with a 3.5 mm output

Purpose

Built-in phone and laptop speakers point away from the listener and run out of headroom. This unit takes the same signal from the jack and radiates it forward without drivers or setup.

Applications

  • Boosted playback from a phone or tablet
  • Desk audio for a laptop
  • MP3 and MP4 player sound
  • Shared listening at a table
  • Travel and hotel room audio

How to Use

  1. Plug the 3.5 mm jack fully into the headphone socket until it seats.
  2. Start the source at low volume, then raise it to a comfortable level.
  3. Set it on a hard flat surface facing the listener for the least muffled result.
  4. If sound stays in the device speaker, reseat the plug and check no case blocks the socket.
  5. Caution: keep the source volume below the point of audible distortion to protect the driver.
  6. Unplug by the plug body, not the lead.
