- Too short a cable (desk: 1.55m wide, result: the boxes can be just as recommended, up)
- Clearly audible noise when the boxes are active and not output sound (By turning the boxes on full and the output source is very quiet the noise even louder than the sound)
- Some very bassy, although the bass can be regulated
- Every now and then are very strong you notice any anomalies in the Bluetooth connection that can only be corrected by restarting (quite rare)

Total: for the money they are really good and even my old Technics amplifier replaced with Magnat boxes
PS: I use the system with a Nexus 5 (Android 5) and a MacBook (Yosemite) in a 3x5m large rooms.
