Bluetooth question for Xperia Support Tech's

Murdock — Mon, 11 Feb 2013 00:53:55 GMT

Hi!

What headset model, made by Sony, work fine with the Xperia U?

I need a device that doesn’t add noise to the voice communication and work fine with mic noise cancellation

My MW600 sometimes work fine and sometimes don’t.

Well, both Smart Headset and Smart Wireless Headset Pro should work just fine with your Xperia U.

Hi!

Should? Hum, is a little bit imprecise.

What the main difference in terms of bluetooth protocol and mic gain/noise cancelation between MW600 and the Headset Pro?

I notice when my voice is louder the other people complain about some noise... but is better than my other's headsets like Bluespoon and Nokia.

In the tech center they don't know the Headset Pro... never seen one.

You're right Sorry, they work well. I've used the Smart Wireless Headset Pro for about a year and never got any complaints about noise, no matter where I've been or how loud I have been speaking. Before I were using MW600 and personally I think they are pretty similar, but the quality of sound and microphone is a bit better in SWHP.

Regarding the technical specifications of the SWHP:

Smart Headset:

Why we have this problem about noise, echo and distortion...

You can explain in technical words...
