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*
