The Mugig Wireless Bluetooth Karaoke Microphone works well. Pairing was easy with my Iphone. Sing time is 4-10 hours on a full charge. The buttons on the microphone include high and low pitch adjustment, male and female voice, on/off button, volume, pause/play and previous and next songs. TRhere is also voice erasing where the voice is removed from the track and the microphone only plays the music. This karaoke microphone is a lot of fun and I recommend it.
