I have a similar hearing loss. Hearing is normal up to about 2 k then falls sharply after that. About 5 years ago I purchased my first set of hearing aids. My current devices are Signia AX. I have 6 hearing settings universal, noisy environment, television, recorded music, outdoor sport, and stroll.
My audiologist had tweaked the universal profile to boost upper frequencies by about 2 db to help with hearing conversations. The recorded music profile takes the 2db boost away.
If I listen to music on the universal profile highs will seem a bit bright and harsh. On the recorded music profile it clears it up immensly.
After going to the hearing aids my quality of life and enjoyment of music has increased.
I have seen some people here fretting about the da converters in the hearing aids and so on. Never occurred to me to worry about that.
The cost of the hearing aids was very reasonable at about $2100 for the pair. For me this is a great investment.
Do they sound the same as my original equipment (ears) no but getting the harmonics back through the hearing aids has given me plenty of enjoyment.
Just my 2 cents worth.
