Bought an Zero 09 with usb for about a moth ago..
 
 
I got pop sounds after some time (10 hours), headset was then Sennheiser Hd 497. ( OPA 627 dual )
 
Now i bought genuine LT1361, ( single). Plugged it in, and the sound was great for about 1 hour, and now i got popping sounds all time listening to music.. Now my headset is upgraded to Bowers & Wilkins P5.
 
 
I dont know what to to with this.. I have tried optical as source too, but it is just the same popping sounds.
 
 
Does someone know? :/

Whats your source? if using a pc do you have the latest drivers? have you checked the cables?

Hi.
 
Using a Laptop as pre. source. Have tried 2 different usb cables, tried take out the power supply (on laptop), have tried a few CD players with optical out, Ps3 on optical, every source make pop and krackle sounds.
 
BUT, sometimes the pop / krackle sounds disappear, and i get clean sound. But i cant find any pattern when this happend  
It can be clean sound when i play ps3, but without touching the Zero, the sound goes over to pop and krackle sounds in game. The same is happening connected to Laptop. 
 
* Its the same with Sennheiser and Bowers & Wilkins headset btw.
 
 
AND, when i turn off the headphoneamp on the Zero, and then turn the volume to 3/4 i can hear pop / krackle sounds on the headset.   
 
I don't understand
