I had the MAV’s with the titanium slim tips for about a week. Then when inserting the HF3 wax trap is one them, the entire receiver came out. I gave them to my HIS and they are now going back to Phonak for repair or replacement.
But I will tell you three things from using them for a week (using Paradise M90’s):
- The sound quality was incredible.
- The titanium domes were the most comfortable domes I have ever had.
- You have to get used to the mechanical click that happens when they switch from open to close and back. It is LOUD.
I can’t wait to get them back however. I hope this info helps.
