    Just wow

    Bought speakers to put on a desk to listen to music (Spotify Connect) but also to get sound for a Mac Mini in AirPlay and for a PC by plugging in with a jack, as well as an optical console.

    It's always difficult to describe the quality of the sound, but whatever the style of music, they manage superbly. The sound is super precise at all frequencies (from bass to treble). No saturation, even at high volumes. No unwanted vibrations. They're perfect for a room of 20m2 or more.

    Some reviews mention that they lack a bit of bass, but that's really a matter of taste. In any case, you can add a subwoofer if you wish.

    In short, they're all very good and I have absolutely no regrets about my investment.
