Like the W902, neither W302 or W595 have headphone sockets. Instead, you'll need to use a bundled extension cable to connect your headphones to the proprietary connection. These days, this is just unacceptable in a music phone. Other manufacturers, such as Nokia and Motorola, are seeing the light and now put proper headphone sockets on some of their phones.
Anyway, annoyances aside, the quad-band W595 is a slider handset, featuring a 240x320-pixel screen, a 3.2-megapixel camera, integrated stereo speakers, stereo Bluetooth, 40MB of internal memory expandable with Memory Stick Micro M2 cards and it weighs 104g.
The lightest handset in the new Walkman range is the quad-band W302, weighing in at 78g. It's got a 176x220-pixel screen, a 2-megapixel camera, stereo Bluetooth and 20MB of internal memory expandable with Memory Stick Micro M2 cards. Sony Ericsson only reckons you'll get 10 hours of music from a full charge, though, which is rubbish.
We'll have full reviews of both models as soon as we can, but click through for a gallery of photos for now. -Nate Lanxon
