until you put them in. Better to go with something from your local store in town so you can try them on first to confirm their fit. I am sooo bummed And hard to get on and off. I use it with Chord Electronics Hugo and Mojo DAC/headphone amps and they match up perfectly. I have increased my rating from 3 to 5. Mic is really outstanding at this price (10/10), no complaints (Tested on PS Party and Discord). FeaturesLove that theres really no buttons and everything is touch. JBL app requires GPS location. That reviewer is absolutely right.
