Top 3 Problems With Receiver In the Canals Hearing Aids 1.  The cost of repair.  The hearing aid is composed of two parts.  A. the part behind the ear that houses the computer and microphone and B.  the Receiver part which is the wire going from behind the ear into your ear canal.   The trouble could be either one.  If your hearing aid dies and its not the wax guards,  If its in computer part, behind the ear,  if the entire circuit is bad..... you need a new hearing aid.   Or it could be the microphone - these are now on the same flex strip as the computer circuit which also means you need a new hearing aid.  or B the receiver.  The receiver takes a beating and I have seen them go out after one year.  The receiver end is vulnerable to moisture in the ear canal These cost $100 up to $500 to replace. 2.  Wax build-up. With the Receiver in the Ear...these now have the same exact issues that IN the EAR hearing aids do.   The receiver is in the ear canal.  You create wax so the wax guard will get clogged up and stop the hearing aid dead in its tracks.  Thankfully wax guards are replaceable.  Here is an image of RIC owner changing out the wax filter.   If you create lot of ear wax.  Its a good idea to make replacing your wax filters a weekly habit.   Wax Guards, filters cost $10 to $20   3.  In the receiver and feedback management.  When you put the receiver in the ear - you just increased the chance for feedback.  That means more squealing.  That is when sound leaving the receiver finds its way back to the microphone.   Comb your hair or get your hand close to the hearing aid or if you put your head close to a wall or seatbelt or couch/lazyboy, its going to squeal. RICs now account for 62% of all hearing aid sales - But RICs are without a doubt the most expensive hearing aid to own. Couple other issues with Receiver in the Canals - Because they are so small and lightweight it can take some time for the user to realize that the hearing aid is missing. Compared to other hearing aid styles, receiver in canal hearing aids are also above average in cost $1399 to $2799
