## Description

Microphone Stand Tripod Adjustable Boom Height

Review: The mic works very well connecting through MIC on my karaoke system. It also works very well connecting through AUX with my bluetooth speakers (Creative and JBL) while they are playing songs via bluetooth. Have yet to try the bluetooth function.
Review: I teach elementary music and use these for doing plays. They are wonderful! They work well, and if you put them on different channels, they don't interfere with each other. Right before my last play about a month ago, I couldn't get them to Bluetooth. I tried all of the troubleshooting techniques and it still wouldn't work. So I contacted customer service and they were awesome! I told them that I was hoping to use them in 2 weeks and asked if they could help me. I had new microphones within just a few days! Very good product and customer service! I would definitely recommend these microphones!!
