PRODUCT DESCRIPTION
Dynamic 15W Acoustic Power featuring BassUp 2.0 Technology
The Soundcore Boom Go 3i comprises a 2.1-inch custom-built full-range acoustic driver coupled with strong 3D metal speaker grille despite its small size. Thanks to Anker’s innovative real-time DSP technology for BassUp 2.0, the speaker automatically manages low frequencies and produces bass with peak sound levels of up to 92dB and signal-noise ratio over 92dB. The Soundcore app allows users to choose from multiple Pro EQ sound settings or specialized sound presets for outdoor use.
IP68 Certification for Water and Dust Resistance and Carabiner Integrated
The Boom Go 3i is specifically designed to be used outdoors with an official IP68 rating for water and dust resistance. The device has been designed to withstand full immersion in water, splashes of mud, and heavy rains, while its buoyancy ensures that it does not sink even in a raging river or during pool parties. Its outer casing offers resistance to shock and has been tested to withstand drops from a height of one meter. In addition, the integrated installation strap allows for the attachment of the device to backpacks, handlebars, and tents among many others.
Marathon 24-Hour Battery, Reverse Power Bank & Bluetooth 6.0 Auracast
Thanks to the use of a powerful energy-efficient charging cell, Boom Go 3i can be used continuously for up to 24 hours (50% volume with BassUp setting) and up to 40 hours in Eco mode. In case of emergencies, the speaker can be used as a reverse power bank with USB-C port to recharge the smartphone or earbuds. With Bluetooth 6.0 technology, the speaker can be paired with any compatible speakers via Auracast technology, as well as with any other Bluetooth device using True Wireless Stereo (TWS) technology. Other important features of the speaker include beat-synchronized RGB LED light and an emergency alarm siren.
