I sympathise @jl1ny
I have Tinnitus too. It drove me mad for the first 6 months. I could only get relief when focused on work or sitting in the shower. The tone of the Tinnitus went through changes too. It took a good year for me to learn how to manage it. It is part acceptance, learning tricks that work for me (getting adequate sleep, hot showers), recognising bad days and not listening to music then).
I dont know the severity of your Tinnitus and it may take longer for it to improve, but it will improve, it’s just a matter of time. I am with the "hold on" group. Give it a year (or more) and try again. It may take longer but there will come a day when you think to yourself that you want to listen to music rather than to the recorded sound of waterfalls, brooks and rivers.
FYI, I got tinnitus while in the headphone phase. In the 4 to 5 years since then, I have acquired 3 different speaker based systems (some of them on Audiogon), while living with Tinnitus. There is an audio life after tinnitus. Of course there are things to avoid, eg loud West end musicals, wedding dinner dances (ear plugs help), and not listening too loud for too long.
Wishing you a speedy recovery @jl1ny and lots of patience whilst dealing with your Tinnitus.
