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: Great product and great customer service!! - 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!! ## Features - Wireless Microphone with Bluetooth Receiver: Built-in high sensitivity professional Dynamic Unidirectional microphone core, transmission distance upgrade to 160 feet (Open place), Bluetooth 32 feet. ◆Enhance Signal stability, No delay, No radiation, Anti-howling, Anti-jamming, Constant frequency. ◆The mic outer case is alloy material which is harder, lighter and more wear-resistant.(Not compatible with TV). - Plug And Play Microphone: No need pair. ◆Only for input devices with 6.35mm (1/4") or 3.5mm (1/8") MIC interface, E.g speaker, Singing machine, audio amplifier, PA system, Voice amplifier, truck speaker system, Dome speaker system etc.◆Rechargeable Bluetooth receiver, which can be connected to smart phone to karaoke on the speaker.
