Yes, and that is one of the reasons I decided to try out the Resound Futures, because even with a custom tip, the receivers can be replaced in the office.
Now, when I was trialing the Wi, I had to give up my Destinies (trade-in). Then when the left Wi failed, I was stuck, and I relized then that I would be too vulnerable in the event of a failure,
So, I’m looking forward to August 11, when the Future’s come in.
