Mono Portable Speaker JBL Go 4 Blue
The JBL Go 4 Blue is a compact mono portable speaker that delivers clear audio for everyday mobile use. Designed for on-the-go listening, it combines a small form factor with wireless Bluetooth connectivity and a built-in rechargeable battery. The speaker provides a rated output of 4.2 W, a wide frequency range from 90 to 20,000 Hz and a signal-to-noise ratio of 85 dB, making it suitable for voice, podcasts and background music from phones and smartphones.
The speaker’s compact size and 0.19 kg weight make it highly portable and easy to carry in a bag or pocket. Bluetooth wireless connectivity supports common streaming profiles for straightforward pairing with mobile phones and other devices. Physical buttons for volume control provide simple, tactile operation without relying on a phone. The integrated 850 mAh lithium-ion battery allows for cordless use, and the mono design delivers consistent, focused sound for personal listening situations.
Charge the speaker fully before first use using the provided charging cable. Activate Bluetooth on your mobile phone or smartphone and select the JBL Go 4 from the list of available devices to pair. Use the physical volume buttons on the speaker to adjust playback level. Place the speaker on a stable surface and keep it within the Bluetooth range of the source device (typical 2.4–2.4835 GHz operating band) for uninterrupted audio streaming. Recharge the battery when needed and avoid exposing the unit to excessive moisture or extreme temperatures.
For best audio clarity, position the speaker on a flat surface at ear level when possible, and avoid placing it inside closed compartments. Regularly charge the lithium-ion battery and disconnect from the charger once fully charged to prolong battery life. Use within the recommended Bluetooth range and maintain up-to-date firmware if updates are available.
