Yeah @Zebras… Twas a pain in the proverbial! I don’t think I got these RIC’s with custom moulds to last more than 10 months, without the Marvel 90’s, blowing a receiver? So much so, I had a set of 105db RIC’s & moulds made up, on stand by for this eventuality… I don’t wear the Marvel RIC’s very often nowadays, but they are without a shadow of doubt, the most comfortable aids, I have ever used! I do wear them occasionally when 1 of my ears flare up, with an infection or a sore (or I just fancy a change) I usually keep them in for a week or so till things die down… Then we are good to go, with my Naida Lumity’s… Cheers Kev
