I have had a GPX Model R2104SH for years (many since 2/1/04?) and the sound is great, loud and robust. When I purchased a replacement Model A321 it sounded like a transistor radio! Actually what I mean is that the sound is too weak and not loud enough for the shower! I will try to get another of the old style with the four double AA batteries instead of this one using two AAA. The A321 feels great to tune, and has great reception but the sound is weak compared to the R2104SH.
This product is garbage. This radio burns through batteries like no tomorrow. I have had this about two weeks and have had to replace the 4 batteries in this radio twice. I only listened to the radio twice in the morning. I have no idea why this small of a device would need to burn through batteries this fast.
