Overall the BlueAnt M1 Stereo Speakers System is one of the most attractive and well designed solutions that I have come across to date. Not only does it deliver clear and powerful sound but it also happens to be extremly versatile thanks to its two wireless (Bluetooth) or wired (3.5mm) audio connectivity options as well as its two power options (wall charger or internal battery) that allow you to conveniently and simply use this unit both indoors or outdoors.
Lastly, please note that only Windows Mobile Treo smartphones (excluding the Treo 700w) offer built-in A2DP wireless audio streaming capabilities. Having said this, you can enable your Palm OS Treo or Centro with A2DP by getting the excellent Softick Audio Gateway (see my review and Bluetooth Stereo Roundup for more detailed information).
