Easily the best and most significant sonic tweak one could ever make!

Hearing aid user since 2007.  Third set, Oticon OPN-1 which was their top of the line 3 years ago.  Bluetooth, all the bells and whistles plus custom molds.  The Oticon have tinnitus compensation which does offset that annoying ‘whistle’ but doesn’t make it disappear.  I’m 69.

How did I know something was an issue?  Besides my wife complaining I discovered that the music I listened to was becoming more distorted.  My system at the time was 70s vintage McIntosh with JBL 4311’s.  I honestly thought something was failing.  I borrowed a friends receiver and heard the same kind of distortion.  Eventually I saw an ENT whose practice had an audiologist and that helped get my issue under control.

Yep, I hate the cost of those things.  For my second set I tried Costco but you are at the mercy of their fitter who may or may not be an accredited audiologist.  They offer a no questions asked refund if you’re not happy, I wasn’t and I had no difficulty getting my money back.

if you can find an audiologist who has worked with musicians that’s a plus.  
You can expect a lifespan of 5 to 7 years for a set of HA’s.   Like everything else older designs lose manufacturers support.  So far no issues with Oticon.

The bulk of my hearing loss was mid-range; bass and lower highs still 'there' even @ 69.  Conversations, individual and group, subject to misunderstandings and misinterpretations.

Certified audiologist, had worked with musicians.

Phonex Audeo' works for me.  Mid-range back in all its' glories. *S*
Phone calls direct to ears; anything Bluetoothed as well.
So much for headphones..

Funny thing, though....my eq settings for mids are untouched from 'before', relatively 'flat'....

*L*  I learned to trust my DSP, I guess. ;)

Maybe a good start is to clean the 10kg of wax out of your ears. Seriously though, speaker positioning and finding the sweet spot is usually free of charge.

Amazing huh the technology for hearing loss improves every day since they are basically EQ’ing the sounds picked up and amplified in your ear by the device. I’m due for a tuning /upgraded software. I remember there were 3 frequency curves - pre-hearing aid, normal for my age, and then the gap filled in by the HA. Doesn’t get you quite to where you should be, but very close in my case and as a bonus my left ear which has mild hearing loss got one too to balance out both sides which is critical.
When I’m listening to music and I take them out, its like a big heavy blanket was thrown over the speakers. Remarkable
