If we were to ever make an IEM system, it'd be much closer to the higher end Shure or Sennheiser price point, not XVive's. Line 6 has zero interest in a race to the bottom, and the whole downmarket 2.4GHz wireless audio space has been heavily commoditized (and the 2.4GHz IEM space isn't far behind). You're either "whoa-this-thing's-$30-on-Amazon-and-does-the-job-fine" or "I need something expensive and professional for world tours"; there's not much demand for in between solutions, where neither the run rates nor margins are great.
A lot of customers just want cheap "good enough" stuff shipped in 24 hours, and that world is death for a company like Line 6. BOSS and InMusic/Headrush have the resources to compete in that space (a loud Alto party PA with 128 RGB LEDs and Bluetooth audio for $99 at Costco?!) but we don't.
"Ha! What about the $179 POD Express?!" one might then chortle. Well, we believe that product happens to fill a gap in the market and targets a new customer. Once the CMs rush in with their $49 POD Express wannabes, we'll have to pivot and find an entirely new gap.
