Not that we haven't ever seen a mobile get that mildly interesting SRS WOW badge slapped on it before, but Philips is becoming the next to do so with its M600. This oh-so-sleek candybar makes a play for the music lovers heart -- well, so long as said adorer is in China, anyway. Aside from providing one click access to your stored tunes (not to mention easy access to volume / track controls), the handset packs a 2-inch 220 x 176 resolution display, 1.3-megapixel camera, microSD expansion slot, Bluetooth, a very welcome 3.5-millimeter headphone jack, support for MIDI / MP3 / WMA / AMR files, USB 1.1 connectivity, dual-band GSM / GPRS connectivity and a number of preset equalizer settings to boot. Best of all, Philips keeps its tradition of providing ultra-longevous phones alive by giving users up to 40-hours of music playback on a single charge. 'Tis a shame there's no information on pricing just yet.

With all these companies honing in on bringing HD capabilities to handsets, we were beginning to wonder when someone would step up and lend a hand on the audio front. Thankfully, both Dolby and SRS Labs have come forward at Mobile World Congress to announce separate enhancements to mobile audio, so we'll touch on the former first. Dolby Mobile, hailed as an "audio processing technology platform that brings rich, vibrant surround sound to music, movies, and television programs on mobile phones and portable media players," is available as we speak on the FOMA SH905i and FOMA SH905iTV in Japan, but will hopefully float out to other handsets in due time. As for SRS Labs, it's boasting its own SRS CS Headphone technology, which reportedly "takes stereo or surround encoded 2-channel audio and processes it using an ultra-low-power Circle Surround decoder to create 5.1 highly accurate channels." Granted, we're still wondering exactly how 5.1 channels make their way though stereo earbuds, but we'd be up for a listen, regardless.
