First off, if you are considering between the XB30 or the more powerful XB40, I highly suggest going with two XB30s (same price as XB40). The sound definition in stereo mode is better, and also being spread out more than the single source of sound, it makes up for lack of volume you would otherwise get from the XB40.
Treble frequencies dip a little at 5khz and start to drop off above 10khz. Extra Bass enhances the low end frequencies well, but may be too strong at close range (3ft) at lower volumes. In other words, they are not crystal clear or crisp, but by no means muddy. For BT speakers these speakers sound excellent.
The speaker will last 15-17 hrs at 75% volume (lights off).
For a good speaker, I feel they lack some functionality. Battery indication is only present by holding down the button and voice announces battery level, or, in the Sony Music Center app.
No power indication lights on unit, or even the BT icon in staus bar. The indication is also only in approximated increments of 25%.
Also, No Micro USB to charge the unit, instead charges with a proprietary A/C pin power adapter (inconvenient).
The Sony Media Center app that is compatible to control the XB30 is also a bit laggy or glitchy and takes a bit of effort to use. But works for the basic function.
Overall really happy with the purchase, and highly reccomend buying two for stereo playback if you are an audiophile.
