Compact karaoke system for families

The Koolcover S12C is a portable Bluetooth speaker with two wireless microphones designed for children and adults. It connects to smartphones, tablets, televisions and personal computers. The unit measures 3.54 in by 2.76 in by 3.54 in and includes a USB Type C charging cable.

Suits home parties and travel, not pro audio

This system fits birthday gifts for girls aged 4 through 12 and casual family gatherings. It offers up to 8 hours of playback at maximum volume. Buyers who need professional-grade audio effects or KTV-level sound reinforcement should look at dedicated PA equipment.

Five voice-change modes and LED lights

The built-in microphone provides five magic sound effects including girl, boy, baby, monster and original voice. Colorful LED lights add a visual element to performances. This feature set decides whether the entertainment value matches the buyer's expectations.
