Feedback The Hybrid receiver
cable is not the right
length 1. Check the Hybrid receiver cable length. If it is too
long, the cable will not sit nicely against the ear
and the speaker unit may sit too low in the ear
canal. If it is too short, the dome may keep
falling out. Adjust so it sits snugly and without
tension. See
Shape the Hybrid receiver cable on
page 22.
2. If it is still not correct, change to a different
length Hybrid receiver.

large Change to a dome with less venting.
