Yes it gets better.mostly. I wear two and when I got them new , or have had them reprogrammed the increase in noise is not good, but you get used to it after a few days.
I don’t wear mine on the bike, mainly because of sweat rather tha wind noise, but that can get tiring on a long ride, also my residual hearing is just good enough to hear anything coming up behind me although I have been startled once or twice.
Worst thing is to dwell on it though, so just MTFU and get on with life 😀
Just had one fitted, walking along a corridor was like being in a wind tunnel, find the whole thing massively distracting. Somehow wasn’t expecting the tinny metallic quality of the amplification, made worse by the thing amplifying my tinnitus . Worried now that being on a bike is going to be a nightmare, ready to give up on it after just a day!
Don’t wear mine for biking , worry about sweat and mud and its always raining except today was sunny , took me a while to get used to the tinny sound , its starnge in a pub with loads of back ground noise odd conversations seem to come through a clear as any thing some are quite funny 😀
