It has good clear voice amplification and is compact and lightweight. I used it all day at a Convention and the battery lasted really well, only seeming to lose power and therefore volume towards the end of the day. The headset is comfortable and the mic position is adjustable. Review: Quality voice - For the price, this is a brilliant gadget. The pretty solid head mic sits comfortably and the amplifier pack fits onto trousers without falling off. As a line dance teacher, this is now an essential item, allowing me to talk instead of shouting, over the music. The range is good too, I can thoroughly recommend this amplifier. ## Features - Effective for Teaching - With a 10-watt output power,the portable voice amplifier with wired headset microphone make your voice louder and travel further, helping students listen more clearly and attentively.
