Thinking of buying an iPhone (probably 6) and was concerned about hearing incoming calls. It’s not the ring tones but voices on the other end of the call. I have a simple Dora mobile at the moment and can hear that easily. However, I asked a friend about this on her iPhone SE. She rang me from another room and the volume was really low. I could barely hear it. We located the + and - volume adjuster which you use once a call begins but although on full volume it was no where near the level of sound that my Dora has. I am concerned that all the iPhones might only offer such a low sound. My hearing is not A1 and I use hearing aids to assist watching tv etc but I can hold conversations on my landline and Dora without any trouble. I am so disappointed as I thought paying out a lot of money would give me better voice reception, not worse. Was my experience likely to be the same across all the iPhones? Would be grateful for advice.
