Speaker system with the highest sound quality. Bluetooth, Optical, remote control, headphone output

Introducing a model ready to redefine what portable sound can be. The SVEN PS-399 portable acoustic system is built for those who refuse to sacrifice audio quality for mobility. This speaker brings together thoughtful engineering, modern wireless standards, and everyday reliability in one compact package.

At the core of the PS-399 lies a three-way acoustic design, with each frequency range handled by a dedicated driver. Two 1.5-inch speakers deliver crisp, detailed highs, a pair of 2.5-inch units brings out the mids with clarity, and a 4-inch low-frequency driver paired with passive radiators produces deep, tangible bass. Total RMS output reaches 100 W, with a frequency response spanning 45 Hz to 20,000 Hz. Combined with a dedicated bass-boost function, this setup allows even a lightweight 3.7 kg enclosure to reproduce music with the volume and detail typically associated with stationary systems. An ergonomic handle and compact dimensions (432 × 193 × 236 mm) make it effortless to carry the speaker from room to garden, or from a porch to a riverside.

Connectivity freedom was a top priority for the development team. Auracast™ support transforms the PS-399 into a personal broadcast hub: stream music, podcasts, or a movie's audio track to an unlimited number of compatible headphones and speakers, all while maintaining perfect synchronization and stable transmission quality. Bluetooth 5.4 ensures a reliable wireless connection over considerable distances, while the AUX input and direct USB flash drive playback give users full control over their audio source — no extra devices required.

The PS-399's endurance and autonomy are engineered for extended use. Its built-in 11.1 V, 4000 mAh (44.4 Wh) lithium-ion battery delivers up to sixteen hours of continuous playback at 30% volume in Bluetooth mode. Recharging takes just minutes thanks to a USB Type-C port with support for modern Quick Charge and Power Delivery protocols, making the speaker compatible with most contemporary adapters and power banks. Meanwhile, the IPX6-rated enclosure means the device isn't fazed by angled rain, accidental splashes, or even a direct jet of water — staying fully operational in any weather.

Completing the experience is a switchable dynamic RGB lighting system that gently pulses to the rhythm of your music, adding visual flair without overwhelming the senses. The SVEN PS-399 is more than a list of specifications — it's a cohesive audio solution where every detail serves one purpose: to let listeners enjoy high-quality sound without limits, wires, or compromise.
