However, the set has a defect which makes it unusable for me:
The woofer of the boxes have a silent defined flattrigen humming,
This is independent of the normal diffuse background noise.
If you connect the set to an average volume PC, it will not interfere well, but with quiet PC and in quiet environments, the noise is clearly audible, even in listening distance. Even with soft music and especially quiet TV shows (with typically quiet frequent breaks) you can hear it out yet.
I have tested the set at various outlets, with mains filter, and even in a second flat. The buzzing is still heard in the same way, regardless of whether analog or connected via USB, even if no source is connected.
The delivered from hell Ersatzset had the same problem. Presumably, the reason is the tight obstruction of power supply and amplifier,
where the noise is induced.
Incidentally admitted the devil support that a slight hum is normal, for safety's sake but a replacement set was sent, but that unfortunately confirmed that it probably is the normal hum in my complaint. It bothers me and I think it is at this price unacceptable.
The service of the devil is unfortunately always very slow and so bad: product inquiries, delivery, complaint handling, replacement, everything takes longer than a week.
