Buying Guide
Match the Size to the Bass You Expect
Small speakers can produce punchy upper bass, but they cannot move as much air as large cabinets with full-size woofers.
Choose the SOUNDBOKS 4 for maximum output, the Soundcore Boom 2 Plus or Sony ULT Field 5 for powerful portable bass, and the Ortizan when easier carrying is more important than room-shaking depth.
Do Not Compare Wattage Alone
Manufacturers may advertise continuous, maximum, or peak power. These numbers are not directly interchangeable.
Driver size, cabinet design, passive radiators, amplifier tuning, digital processing, and distortion control can matter as much as the stated wattage.
Consider Where You Will Carry It
A speaker can be battery-powered without being easy to carry.
The SOUNDBOKS 4 is transportable but heavy. The Sony ULT Field 5 and Soundcore Boom 2 Plus are suitable for short-distance carrying, while the Ortizan and Sony ULT Field 1 are easier to take on regular trips.
Understand Battery Claims
Maximum battery figures are usually measured at moderate or low volume. Bass enhancement, lighting, phone charging, outdoor temperatures, and high playback levels can considerably reduce runtime.
Check the Water-Resistance Rating
- IPX6: Protected against powerful water jets, but not immersion
- IPX7: Protected against limited temporary immersion
- IP67: Dust-tight and protected against limited temporary immersion
Charging-port covers must be closed securely before exposing a speaker to water.
Use Bass Modes Carefully
Bass-enhancement modes can add impact at moderate volume. Excessive boost may reduce vocal clarity or cause the speaker’s processing to limit output at higher listening levels.
Begin with the default tuning and increase the bass gradually.
