Bluetooth Dual-Speaker Voice Amplifier with Headset Microphone for Teachers & Meetings — 2000mAh Battery, Up to 21 Hours, Covers 10000sq

Portable dual-speaker voice amplifier that boosts projection and protects your voice. A dual-microphone arrangement delivers clearer, softer speech while a high-frequency speaker paired with a full-range speaker reduces distracting environmental noise so listeners hear you distinctly. Designed to reach every corner of spaces up to 10000sq. Versatile connectivity: pairs with mobile phones via Bluetooth, plays music from a TF card, supports FM broadcast and offers recording functionality (recording requires inserting the microphone). Power and runtime: built-in 2000mAh lithium battery provides up to 21 hours of amplification and up to 10 hours of continuous music playback; full charge takes about 3 to 4 hours. Adjustable headset mic: flexible gooseneck places the microphone close to your mouth and the top-of-head headset design stays stable during use; compatible with UHF headphones (not included). Strong, lightweight and easy to operate — ideal for classrooms, meetings, outdoor events such as weddings, and tour guide use.
