I've had this phone for two months. No problems. The ear speaker must be located differently than my last sony ericsson because I find myself moving the phone to get better sound. But once i find it, the sound is fine. Sounds like all the other phones we have in our family. Most of which are Nokias. I do not have the bluetooth headset. I have not found the 525a holster. Only the 520a holster and don't know if it will fit. So, I carry it in my pocket or purse. Camera is fine. Rings are ok, not a great selection, but you can record anything, including the name of the person calling --waved with their number in the address book. The ring is loud. I can hear it ringing all over the house. When the time came to renew my cell contract, I bought this phone because my old sony still worked after six years and I hope the longevity of the new one is equal. Not a perfect phone because I wish it had an FM radio feature like the similar Nokia. And I'm not happy that the old charger does not fit this Sony. I've got THREE of those and now only ONE that I can use.
