My Garmin Rino 755t HTs are very quiet. Initially I thought it was a wideband>narrowband issue, but the FCC docs for the 755t show that it is narrowband-only. I really only use the Rinos for texting and sending location data to hunting partners so it doesn't bother me much. When I try to use it in a noisy environment I have to put the speaker pretty close to my ear. They "support" BT so you may have luck pairing a Bluetooth headset to the Rino.
