The phone has just 32MB of on-board memory, but has a slot for Memory Stick Micro (M2) cards in the side and comes with one in the box. Bluetooth can be used to transfer tracks, and for wireless stereo headphones. Otherwise, use USB - there's a typical Sony Ericsson port on the side of the phone, around from the M2 bay. Once again, Sony Ericsson's buky earphone connector is awkward and prone to snagging in your pocket.

A pair of average-quality wired earphones are supplied, which provide a presentable audio performance. Swap them for better headphones - such as some Walkman earphones - and you get a noticeable step-up in quality. There’s no 3.5mm jack socket on the Z770i phone or on the supplied headset, so you’ll need an adaptor to add standard 'phones. If you’re into your music, it’ll be worth it, because the player is actually pretty good through higher quality ear gear.

The 2.2in internal display is reasonable

Sony Ericsson reckons this clamshell can keep going for up to 8.5 hours ' conversation on GSM networks, or 4.5 hours on 3G networks. Standby time is estimated at around 14 days', so we expected a decent power performance. With our average level of usage, including tune playing, camera work and surfing, the Z770i managed three days between charges – a more than acceptable real-life figure.

On the basic call level, the Z770 hit the mark fully with a high quality and reliable audio performance plus steady network connectivity.

Verdict

The Z770i fills a welcome spot in the consumer 3G line-up as a decently equipped mid-range clamshell phone. It’s sleek and slim, and has an elegant design with some stylish appeal, both outside and once open. The features and functionality inside offer little in the way of surprise or innovation, and Sony Ericsson still seems determined to give its Cyber-shot range the best deal on the imaging front.
