Like the K660, Z770 is marketed as a web phone for the youth. The built-in web browser is Access NetFront 3.4, although it’s slightly enhanced compared to i.e. the one in the current K850 firmware build. One of the few added features is the mouse cursor, which makes it a lot easier to navigate large websites. Another feature making it easier to navigate larger sites is the enhanced zoom features with a zoom map.
There is no support for Flash, but some light Java scripts are supported.

Honestly, I’m not too thrilled about the sound quality during phone calls. In my opinion it’s a bit distorted, and the fact that it’s as loud as it is, makes it even harder to hear what’s being said. Having said that, it’s far from impossible to understand what the other person says, it’s just not as good as it could have been. There’s really no background noise, though, so that’s a plus. You can put in on speaker as well, which actually works quite well, although you’ll have to close the Z770 to get the best sound, meaning the microphone will be blocked.
As said earlier on, the Z770 comes with a Bluetooth headset. The battery life on this one is quite good, and it didn’t run out of battery at all in 12 days of constantly being turned on and connected to the Z770. That’s the way it’s supposed to be! While that isn’t bad, the sound quality isn’t exactly great. It feels like it’s echoing when talking in it. The microphone is quite good, although I would have prefered dual microphones. The fit wasn’t very good on my ear - the headset ring was simply too small, and my ears aren’t exactly the largest in the world, so that’s actually quite bad. The size of the ring can’t be altered. You can however use it on both your left and right ear.
