What is your audiogram range? I think people at where you've stated just prefer to just play without hearing aids. The warm tones may be a bit lost and bright tones my be sharp. Depth of sound may also be a little lost with everything sounding right at surface level.
However, if you have particular ranges that are weak, hearing aids will help balance it out.
If you don't like string noise now, it will be double with hearing aids.
But if any curiosity exists, I would take them up on the one month return policy. You've got nothing to lose.
If in your day-to-day life you get by at 95%, you may not need the hearing aids. For a small amount of hearing loss, the initial cost, the up keep, batteries, and "trouble sounds" that you will get with hearing aids may not be worth it.
But having said that, I know what it's like to be deaf and return to the hearing world. In your case I would try it.
