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

Yea, I also wear earplugs at loud concerts  Thanks for the information.

Interesting too is the fitting process.  They gradually (over a period of weeks) adjust them to compensate for whatever frequencies you've lost  (If they do it all at once, you can't tolerate it).   But the brain soon gets involved (as it does in all matters related to audiophilia or mis-audio):  it 'compensates for the compensation'.  You'll notice this in many ways, but the most striking feature for me was how much the hearing aids sensitized my brain to sounds I was NOT hearing before.  When I took them out, I could actually hear those frequencies (or some of them) without hearing aids.  God knows how much this affects our hearing of music:  I go to live music to learn what live music sounds like (and I'm sure my brain then translates my audio system's music into that).  I'm also sure my home audio trains me to hear details in live music I might have missed in the massive wall of sound at, say, a symphony.

@electroslacker Appreciate you relating this story. We often fail to appreciate that which we take for granted.

No feedback, no distortion other than that of the head betwixt...*G*

I've been fitted for 'in canal' pieces with the receiver/driver 'on ear', the only issues being my glasses (nearsighted) and removal of the au courant' maskings...

Reasonable comfy, although my Q-tip use has gone up....*L*  'Before and after' install in ears just feels good to do....😜

I'm wearing them f/t, as my speech recognition was a main issue w/spouse and conversation in general.  As for listening to music (or what I listen to, which is subject to discussion...), they stay in.  Otherwise, the eq would be 'ideally' warped to my ears, and sound wierd to others.

The only limitation I'd note is the limits of the 'on-board' eq, which is really pretty basic.  But hoping for 1/4 octave eq in a h/a is a bit of a stretch...;)

Overall, I'm pleased.

MC, I'd agree on eq'd headphones with a dedicated amp for the 'serious listening hour(s)', but a bit of overkill in some ways....clunkly unless Bluetoothed...one can forget you're wired into the stack.  Nothing like having the cans yanked when you're trying to reach that which is 'just out of reach'.  We've all been there at some point. ;)

And, even then, you'd have to corelate your 'loss' with the eq you need.  Do-able, but again, subject to taste and preference, which may not end up 'correct' in an audio sense....

'Practical vs. theoretical', yet again...*S*

Interesting discussion. I am close on getting hearing aids but have a question of principle understanding:
The hearing aid - from a principal point of view - consists of a microphone, an amplifier and a speaker. If you listen through this device, doesn't that have an influence on the sound quality, i.e. isn't what you are hearing the sound quality (?) of the earpiece rather than your hifi system?
