i have a very strange problem i cant figure out myself:
i bought my z-10 about 1 year ago and so far i was really
satisfied with them. since today.
they worked like a charm since today. i used them yesterday
with my itunes and as always everything was fine.
when i switched them on today, there was a loud buzzing
sound for 1 sec. and then dissapearing for 2 seconds from
the right speaker. since then, i do have sound, but the
buzz returns every 20 to 40 seconds from the right speaker.
plus i think the right speaker is a bit more silent than the left one..
they are connected via USB and i changed nothing during the
last couple of weeks/month.
*EDIT* maybe i should mention, that i run winXP
the buzz even occurs if i unplugg them from my pc and i cant
control the buzz-volume (tough i still can control the volume of
my pc audio. thus i think its no USB or software issue, but i
might be wrong..
im really looking forward to get some help!
thanks in advance,

I believe it may be a defective capacitor in the amplifier section, possibly caused by use of poor quality components and a design that allows overheating, especially at high listening levels. I have this exact problem, and sometimes the powered speaker cuts out completely. I will open the speaker up and replace the amplifier capacitors - will let you know if this cures it.
