Sony Ericsson recently presented their latest Greenheart tree-hugging phones – aptly named Elm and Hazel. Both the devices pack pretty much the same features – 5 megapixel auto focus cameras, Wi-Fi connectivity and GPS receivers complete with the preinstalled Google Maps and Wisepilot mapping apps, the only difference being that the Hazel has a slider form factor while the Elm is close to your regular Sony Ericsson candybar.

All Android rumors have been put to rest as both the devices run on Sony Ericsson’s proprietary OS,  the fresh look that we saw in spy pics being due to social networking integration via homescreen widgets.

Screen resolution remains at the QVGA standard (320 x 240 pixels), but what’s surprising here is that the one on Hazel is 2.6 inches large and sports a 16.7 million colour TFT, whereas it’s only 2.2 inches on the Elm sporting a 262.144-colour TFT.

What’s new here is that they both pack in some innovative sound enhancing technologies such as Noise Shield, Clear Voice and Intelligent Volume Adaptation. ‘Clear Voice’ is a technology that is supposed to make a caller’s voice more distinguishable from eventual background noise whereas ‘Noise Shield’ does the opposite,reducing background noise during a call in order to improve the voice quality for the recipient of your call.

The Sony Ericsson Elm will be available in Metal Black and Pearly Rose from Q1 2010. The Sony Ericsson Hazel will be available in Superior Black and Passionate Rouge from Q2 2010.
