Speech in Noise, while maximizing the noise reduction settings, also increase the overall volume a little more, supposedly to help you hear better. But depending on your hearing loss (which we have no idea what it looks like because you don’t post your audiogram in your profile), the increase in volume may not be a welcome change for you. Have you tried turning down the volume of your OPN a click or two in the Speech in Noise program?
The Comfort program, on the other hand, reduces the overall volume a little bit, on top of not giving you maximum values in the noise reduction setting.
So like I said above, try something in between, like be in Speech in Noise, but decrease your overall volume (just use your volume button on your OPN), to see if it helps.
This may or may not help depending on your hearing loss (which we don’t know what it’s like without you posting your audiogram up). There may be other ideas (like using Speech Rescue), but that depends on knowing your hearing loss (again) to see if it’s suitable or not.
