Double the Bass

Exclusive BassUp™ 2.0 amplifies every beat, delivering deep 56 Hz bass for a truly powerful listening experience.

Note 1: Lab tests indicate that Boom 3i delivers a 3 dB increase in bass power within the voice frequency range (56 Hz-20 kHz) compared to the leading industry benchmark-resulting in twice the bass performance.

Note 2: Upgrade to the latest firmware via the soundcore app for enhanced sound quality.

2x Bass Power / 96 dB Loudness

Note: Engineered to withstand 240 hours of salt spray-5x the industry average. Lab-tested to ASTM G85-equivalent conditions.
