Reliability Technologies
The portable speaker Sony ULT Field 3 emphasizes autonomy and durability, making it suitable not only for home entertainment, but also for long hikes, camping, and night parties in the wild. The energy-efficient system, along with a high-capacity battery, provides up to 24 hours of continuous sound, with quality remaining stable even at high volume. Fast charging is supported: just 10 minutes plugged in offers about 2 hours of playback. Additionally, the speaker can function as a power bank, ensuring your gadgets remain charged even far from civilization.
The casing is completely protected from water, sand, dust, and rust, and withstands minor drops. For easy carrying, there are fixtures for the included shoulder strap. The only caveat is the 1.2 kg weight, which may slightly limit user mobility.
Acoustics for a Mega Party
The device's functionality supports Stereo Pair and Party Connect modes, expanding acoustic capabilities. The latter allows you to combine up to 100 compatible speakers into a single system — an excellent solution for big parties, events, and outdoor festivals. All settings are available in the mobile app, including manual equalizer adjustment.
Two separate speakers — a woofer and a tweeter — are responsible for processing high and low frequencies. The intelligent ULT Power Sound technology adds rich bass to the sound and conveys the atmosphere of true Deep House. Sound Field Optimization algorithms analyze the surrounding space and help reduce noise during voice calls via the built-in microphone.
