Sony yesterday posted on its product blog to raise awareness of the fact that the Xperia T is HD Voice certified.
HD Voice technology lessens background noise while improving the sound quality of the human voice. There’s a sound clip here that demonstrates the difference between a handset with and without it.
To take advantage of HD Voice technology, you will need to use a network operator that supports it. In the UK that is Three, Orange and T-Mobile.
We’ve got more stock of the SIM-free Sony Xperia T due to arrive at Clove next week.
