As Marc Chacksfield over at techradar.com notes, the RDP-X60iP, which has a 20W+20W output power, is the very first speaker dock from Sony to include Bluetooth functionality. This of course means that users are able to stream their music from any Bluetooth compatible device direct to their dock.

However, if you’re looking for speaker dock with a little more portability, then the Sony RDP-M15iP dock may be the model for you. The RDP-M15iP has half the power (10W+10W) of the RDP-X60iP model, but does feature a rechargeable battery that will keep the dock going for 6 hours.

The RDP-M15iP also comes with a handy travel pouch to keep your speaker dock safe. The final model unveiled by Sony is the compact RDP-M5iP dock. This model requires four AAA batteries, and should provide you with around 10 hours of listening time. It also comes with a grab handle.

Both the RDP-Mi5P and the RDP-X60iP models have been given a UK release date of June, while the RDP-M15iP will be arriving in the UK sometime in July. Are you thinking about buying a new iPhone / iPod speaker dock?
