The SVEN PS-390 in a sleek black finish is a portable boombox designed for those who want to take their music anywhere. It delivers a total output power of 50 W through two 25 W drivers, complemented by passive radiators that help produce deeper bass across a frequency range from 50 Hz to 20,000 Hz. You can connect your devices via Bluetooth 5.0, use the 3.5 mm AUX input, or play files in MP3, WAV, and FLAC formats directly from a microSD card. Built for outdoor use, this black speaker features an IPX5 water-resistance rating, meaning it can handle splashes and heavy rain without issue. The durable plastic housing measures 390 x 137 x 175 mm and weighs 2.7 kg, making it manageable to carry thanks to the integrated handle and detachable shoulder strap. For a more immersive experience, you can pair two of these units using TWS technology to create a wireless stereo system. A Li-Ion battery with 3600mAh capacity provides up to 17 hours of playback at 30% volume, and it takes about 4 hours to fully recharge via the USB Type-C port. Interestingly, the device also functions as a power bank, allowing you to charge other gadgets through its USB port while you listen. To add some atmosphere to your environment, the system includes dynamic RGB backlighting that stands out against the black chassis and can be switched to suit your mood.
