The whole is very easy through Bluetooth, AirPlay or Spotify Connect. My Sony Tablet recognizes directly that this is a aptX unit, playback is performed without error. I personally use the device with Spotify Connect also works very well! The playback via AirPlay on Apple TV works without error or delay.
Simple, unobtrusive and a bit 90's - to win (probably) no more Design Award.
What strikes you immediately is the bass, dominant and with neat punch. The Bass If you increase the volume almost felt pretty impressive for the small size. The bass is not analytical or precision, but fun. Even at high volumes stable levels, which eventually the built-in DSP bass somewhat reduced.
I fancy that the heights of the devices from B & W to come across a little better, for example, at the A7 or the Zeppelin. (!) The audibility at high levels is not optimal - but hardly anyone on the idea of the unit come to put so loud. The one or other instrument such as Saxophone or violins might sound a bit more natural, where alternatives such as the B & W A7 or Blue sound pulses also cost almost 700. I personally have in the all-in-one solution does not claim that all instruments are played 100% accurate.
The centers are easily withdrawn, which is difficult in this price range. In general, the voice reproduction is good, there is here and there songs where the bass superimposed something the centers. But this is a physically related problem of such devices, the individual speakers are not placed on the level of several meters from each other.
The sound sounds pleasingly open and larger than one would expect, clear the space is somewhat limited - it saves space and is relatively mobile within the apartment / house.
If you want to spend less than 500 you should pull the iTeufel Air Blue into consideration. A really good device for a fair and reasonable price. If you rather tends towards 700 and have an iPhone / iPad, would be the B & W A7 (sound) probably a better choice. Personally, I see it like this: Such all-in-One solutions are there to play music in the background to provide sound a little party or something for the bedroom / study. Whether such devices really need to cost 700, is your decision. For a little more money (about 1000} you already get 2 active speakers with AirPlay such as the KEF X300A wireless. For the current price (399 at Teufel) the iTeufel are an absolute buy recommendation!
