One little-known feature of Telstra’s mobile network is HD voice – but boy, you’ll know it when you hear it.

On calls between supported phones like the Samsung Galaxy SII and Samsung Galaxy SIII; you’ll notice your caller sounds like they’re right there in the room with you.

HD voice also includes background noise cancellation technology, which makes it much easier to chat with someone when they’re somewhere noisy like a busy street, footy match… or a drag race.

Check out a quick explanation of Telstra HD voice on the video below.
