Sorry, I dont use the service.

Upgraded from V40 to 60 T-Mobile @ release . Sounds still great with outstanding battery life (5000mah) and dual screen.

I have Tryed triggering high impedence mode using a trrs 4 pole short male to female extension with no luck. I plug it into the hp jack while my Koss porta pro are plugged in and I get High impedence mode but when I unplug the koss to insert my low impedence in ears the phone triggers back to...

Has anyone identified ear tips that will fit the quad nozzles other than the Comply 600? I was able to get a Jvc Spiral dot to fit but its a pretty tight stretch fit, sounds pretty good.
