Question
Can I use my Motiv mic with the Smule Sing! karaoke app?

Answer
MOTIV microphones with headphone jacks (e.g. MV88+) should work with the Smule Sing! karaoke app on iPhone models 8 and up. It is necessary to use the built-in headphone jack on the MOTIV microphone to hear the backing track.

For iPhone models prior to iPhone 8:

The MOTIV MV5, MV51, or MV88 microphone should work with the Smule Sing! app on an iPhone 5 or iPhone 6. Connect earphones / headphones into the phone's headphone jack, not the MOTIV mic's headphone jack.

MOTIV mics do not appear to work with the Smule Sing! app on the iPhone 7.

Earphones / headphones that have an built-in mic may not work properly, as this mic takes priority when plugged into the phone earphone jack. Use of the Shure EAC9BK cable should resolve the issue; a similar cable is included with the MV88. These cables have a 3.5 mm male Tip-Ring-Sleeve (TRS) connector on one end, and a 3.5 mm female Tip-Ring-Sleeve (TRS) connector on the other end.
