First off, if you have significant hearing loss, consider speaking to an audiologist and getting a set of programmed hearing aids like Beltone or other variety.
If you have mild hearing loss or are just beginning to not hear things in your surroundings or need the television turned up, these might be for you.
The first thing to do is determine if you can handle the in-ear canal hearing aids. Ask for a demo and wear them. If the demo (non-functioning) don't irritate your ear canal too badly, then you are a candidate. It does take a little wear time to get used to them, and the Flexi Fibers (bristles that hold the hearing aids in place) are adjustable (large or small).
Changing volume is strange, but works, simply gently tap your ear while wearing one and the volume changes (a woman's voice says "program 1." Each swat of your ear changes the program from 1 to 4 and then back to 1). I have had people ask me if I'm okay!
These really do work and again, if your hearing is not practically gone, these volume adjusters will work for you. If you have specialty hearing (high end or low-end loss), these might not work, but if you generally need to hear better, these are a good answer.
The charger is great and really holds a charge for quite a while. When the aids battery runs low, you simply pop them into the charger that is conveniently oval and round and fits nicely in a pocket.
Your Eargos are not waterproof so you will need to develop habits that include never washing a pair of pants until you check for your Eargo charger or before you get in the shower, removing the aids first!
They are worth the $2000 price tag. I love mine.
Bottom Line: Yes, I would recommend this to a friend
