I can connect to many statements made above me only here. The box looks unquestionably good and high quality. The sound is tired but in fact quite bass-heavy, but is of course Geschmachssache. Biggest gripe: the Airplay wireless reception is unreliable. The reception characteristics I do not want to criticize primarily here. Although the box is really on quite quickly that the signal strength is low even in areas where other devices still "full scale" show but aborts the music reproduction has not done with me. Problem was the incompatibility for me with the Telekom router Speedport 921V: the AirSpeaker does not recognize the wireless router, wired, there are no problems. This problem is in the network also known (see, eg, telecom Support Forum), but there is probably no solution. Also an update of AirSpeaker firmware did not help. I then tested the speakers at an Asus RT-N56U Rooter. Here I noticed another problem: the AirSpeaker is after he went into standby via Airplay / WLAN no longer wake. You must then manually turn off again at the equipment off and on.
If the AirSpeaker is connected via network cable sure not a bad device with good optics, but via WLAN to problematic. However, it should, in my view, a device called the AirSpeaker be reliable WLAN. Therefore, I have returned the device.
