Bring the music – and the fun – wherever you go with the Block Party portable speaker. Its 4-inch full-range driver delivers deep bass, clear mids, and smooth treble, and two included wireless microphones let you sing along with six exciting voice effects, including high pitch, low pitch and reverb. Play audio via Bluetooth v5.3, Micro SD, USB, or 3.5mm aux input. Six color-changing light modes create the perfect ambiance for any occasion. The built-in rechargeable lithium-ion battery provides around six hours of playback at 50 percent volume (wireless mics last up to 10 hours), making it easy to party anywhere. Controls on the speaker and microphones let you adjust volume and effects without missing a beat. Convenient carry handle and microphone holders make setup effortless.
