These are the exact model
As mentioned, the biggest question to ask yourself is what route you're going to go when getting a pair if you think you need them.
1 - Online (probably the cheapest route)
2 - Hearing aid "store" or box store like Costco (middle road price?)
3 - Ear, Nose and Throat doctor's office (most expensive route IMO).
A couple of years ago, I went into a "hearing aid store". They gave me a hearing test, showed me the wax buildup in my left ear (looked pretty bad IMO), told me they would call me back with a recommendation. They called me once, left a message, I called back, got a answering machine, left a message, and I never heard back from them. I wasn't motivated to follow up with them.
Earlier this year went into Costco. Before they even gave me a hearing test, they showed me the same build up in my left ear, told me I'd have to go to a doctors office and have them clean that left ear out. Called doctors office, they sold hearing aids, and said screw it, I'll do everything in one shot.
My local costco also did not have an "audiologist" on hand (I have no clue how one receives a "audiologist title").
Costco sells the same brand listed but under their Kirkland brand name (I could never pin point the exact differences between the costco brand and the brand given).
The price from costco was around $1,700 per unit.
The price from the doctors office was $3,250 per unit.
There is a part of me kicking myself for going the doctors route per price, but at this point, having 4 visits and my left ear cleaned out (no charge LOL) I can say I'm glad I went that route. My audiologist has a masters and PHD in audiology from the University of North Carolina and really seems to know her crap inside and out (she didn't tell me about her degree, but did notice it in her office).
After my first visit to the doctors office, found out about "care credit", made a 3 minute phone call and qualified for 0% interest for 12 months, which made the more expensive purchase more palatable to swallow.
The only downside to the hearing aids is that after being married going on 18 years now, my wife has finally determined that at times I just tune her out when she's talking to me as I can't blame anything on my hearing now
