Altifalante estéreo portátil Energy Sistem KaraokeStar preto

The Energy Sistem KaraokeStar Black is a portable stereo speaker designed for karaoke and general audio playback. It delivers up to 60 W RMS power from a compact cube enclosure, offers Bluetooth wireless connection, and supports playback from USB and microSD/SD cards. The speaker includes two wireless microphones, an integrated phone slot and LED lights, and is splash-resistant with IPX4 protection. Its 2.0 full-range configuration and frequency response make it suitable for vocal-focused playback and small gatherings.

Advantages

This speaker combines a 60 W RMS output with True Wireless Stereo (TWS) capability to link two units for broader sound coverage. The built-in long-life battery provides up to 8 hours of continuous use, and two wireless microphones are included for immediate karaoke sessions. Multiple playback options (Bluetooth, USB, microSD/SD) and a dedicated phone slot make it easy to queue tracks and follow lyrics. The unit is lightweight and portable, with a strap for carrying and IPX4 splash resistance for outdoor use.

Suitable for

• Home karaoke parties and casual singing sessions
• Small gatherings, backyard parties and picnics
• Portable audio for outdoor activities where splash resistance is useful
• Users who want simple playback from phone, USB or memory card

When it may not be suitable

This compact speaker is not intended for large venues or professional live sound reinforcement where higher power handling, more drivers or dedicated PA systems are required. If you need deep, extended low-frequency bass for large crowds, a larger subwoofer or higher-power system would be more appropriate.

How to use

Pair the two wireless microphones according to the included instructions and adjust microphone and music levels using the speaker controls. To expand stereo coverage, enable True Wireless Stereo and sync a second compatible unit.
