It seems that Sony Ericsson is gearing up to have a bit of a keynote of theirselves as the above flyer has recently been posted letting us know that the way we listen to music will change forever on September 21st.

Now, this is a bit of a zealous claim considering Sony Ericsson is continously pumping run-of-the-mill MP3 playing headsets so the same should be expected here. However, we can’t write the handset manufacturer off until the keynote actually rolls around. According to SE, the announcement will have to do with Bluetooth audio quality and ‘free energy’.

Check back around September 21st as we’ll keep you updated.
