I have tried out the S605 for a few days. Besides the stereo ear plugs, it comes with a short mono ear plug in case you wish to use it for phone calls only, or for listening to mono mp3 music. This short mono ear plug is not suitable for listening to radio which depends on a longer wire to act as the antennae.
This S605 appears to be developed for Asia market. Could not find the specs and features in Motorola site. Perhaps it is just recently released.
Found the following info on it from HWZ (AU)'s press release at
http://www.hardwarezone.com.au/news/view.php?cid=2&id=11179 :-
• Ultra lightweight at 17 grams
• Has a built-in FM Radio with five preset radio stations
• Allows for easy toggle between calls, streaming music and FM radio
• Music can be remotely controlled; skip track, lower/raise volume, pause/play
• Able to accommodate standard 3.5mm headset jack so that users can use their favorite headphones or those included
• Music can be streamed from any brand of compatible Bluetooth stereo phone or music device that support Advanced Audio Distribution Profile (A2DP) and Audio Video Remote Control Profile (AVRCP)
PRO : as above
CON : no lcd display for caller-id or radio/music status.
Also, when it is ON, and I use mobile broadband on the phone, the bluetooth connection is disconnected. Can someone else confirm this?
