As far as I know, the quality of the TCH's handsfree sound has little to do with the mobile phone being used. I have some issues at times with the TCH's handsfree sound, but think that the Sanyo Katana is doing its job perfectly. There are some posts on here regarding how to tweak/adjust the TCH's handsfree sound quality, but I haven't had time to try any of those suggestions.

For me, the quality seems very good, and I have had few complaints from listeners on the other end. It may depend on other factors, too, such as background noise from A/C, road noise, your voice's unique qualities, etc. Oh, and of course you have to be oriented toward the microphone.

In general the Katana has much better reception, fewer dropped calls, etc., than did the Samsung piece-of-caca that I first tried with Bluetooth.

Hope that indirect answer may help!
