The SVEN PS-650 is a versatile portable acoustic system designed for music playback and karaoke. It delivers a total RMS power of 50W through a 2.0 stereo system, utilizing two 100 mm low-frequency drivers and two 35 mm high-frequency speakers to cover a frequency range from 45 Hz to 22,000 Hz. You can connect your devices via Bluetooth, USB 2.0, or a microSD card, and there is an AUX input for wired connections. For those who enjoy singing, the system includes a dedicated microphone input with its own volume control and an echo function to enhance vocals. Constructed from black ABS plastic, the speaker measures 47 x 24 x 24 cm and weighs 3.85 kg, featuring a convenient carrying handle and the ability to be placed either horizontally or vertically. A built-in 4000 mAh lithium-ion battery provides up to 10 hours of playback, while a Micro-USB port handles charging. The experience is complemented by an LED display, dynamic RGB backlight, and an FM radio with an included external antenna. If you own two of these units, the TWS function allows you to pair them to a single source for a wider soundstage.
