I’ve got the more 1 and am self programming with some help from my audiologist. I had the same issue with loud voices distorting briefly, I thought the sound was a bit like a submarine wooshing past.
I solved it completely by turning off the feedback control, it’s far too aggressive. Turning it down to low helped a bit so you could start there. I have no feedback issues with it off, but of course it does squeal a bit when taken out of the ear. Small trade off for me.
If that doesn’t help, turn down the transient noise management as well. I had some residual distortion after reducing the feedback which I solved by setting that to low - but I didn’t need to turn it off completely.
I went from having this issue constantly to never having it with those two tweaks alone. Don’t decrease your amplification just yet!
your 2nd question: I use the TV adapter with my laptop, but it doesn’t work that well. It has an auto shut off feature that kicks in when the volume drops, so I have to keep manually re-enabling it. I suppose that makes sense on a TV but not on a laptop when you play and pause videos now and again. Sounds like people have a better time with the connectclip.
