Verdict

The Energy Sistem FS600 is a portable 2.1-channel wireless speaker that features a total power output of 20W, driven by two 1.5-inch full-range 5W speakers and an integrated 2.75-inch 10W subwoofer. Operating over Bluetooth 5.0 with True Wireless Stereo (TWS) capability for pairing two units, it offers extensive connectivity including an MP3 player via USB or SD cards (up to 128 GB), an RCA audio input, a 3.5mm mini-jack input/output, and a 4,000 mAh rechargeable battery providing up to 12 hours of playtime. Key advantages include deep bass performance, a built-in display, versatile physical media slots, and integrated voice assistant support. However, notable drawbacks include its lack of water resistance rating, a heavier build at 1.28 kg, and a lack of fast-forward or rewind control functionalities.
