Verdict

The Energy Sistem KaraokeStar is a 1.92 kg portable 2.0 sound system featuring 60W of output power, two passive radiators, dynamic drivers, and a frequency response of 80 Hz to 18 KHz. Main characteristics include modern Bluetooth 5.4 connectivity with a 20-meter range, an integrated smartphone slot for reading lyrics, an MP3 player compatible with up to 128 GB microSD cards and USB drives, a 3.5 mm analog audio input, and customizable LED party lighting. Key advantages include its IPX4 splash-proof durability, True Wireless Stereo pairing to synchronize two units, a 3,600 mAh Li-Ion battery providing up to 8 hours of playback, and the inclusion of two wireless microphones alongside a 2-month SingSnap subscription. Notable drawbacks include a lack of a dedicated physical battery level indicator, restricted low-frequency reach down to only 80 Hz, and the absence of high-resolution audio codec support beyond basic SBC.
