I use the SoundStation in conjunction with a PicoPix 3610. The sound is true to size well, with a certain room size is of course at some point circuit and the signal is compressed strongly and distorted. It is not about heavy bass Musikvideso, but documentary films with high speech content. In a classroom with 20 students it is just like that. Which reminds me, of course, it was already clear that the physics can not outwit and 2x2 Watt quickly reach their limits. So if you expect any miracles, then the sound turns out to be quite practical and the SoundStation as a good complement to the projector. However, what did not work, is the battery life - the PicoPix alone creates with me just 10 minutes even in conjunction with the SoundStation is to max. 30 minutes final. Thus, one wired (= mains) must work yet again. I had imagined quite differently, and therefore I can the statement "up to 4 hours of battery life" only be described as a brazen advertising lie. Mind you, both batteries (3610 & SoundStation) were fully charged the night before use and the films were not of a power-hungry external hard drive, but from an SD card. That the battery charge and otherwise retains not good, showed me several futile attempts to start the 3610, even though the battery was only after 7 days before fully charged. So all in all though a good product and a useful addition to PicoPix projector. But with the battery life can better the competition - Philips, please make improvements!
Reminds me of the projector even in that the headphone output delivers extremely little power - in conjunction with an external speaker was despite this full-stop (which was the other players each have close to the threshold of pain) to elicit only a whisper. But perhaps I have since also caught a Monday model ...
