pda and wireless headphones problem

[Guest robs23]

Hi. I've owned mio p550 and bought Logitech Wireless Headphones for it. While listening to music through those headphones, sound crackles every 2 seconds...Why's that? It helps when I switch off the display on pda. Do you think it's caused by too slow processor of my pda (about 400mhz)? I read some test, and the author said that on his mio p550 those headphones works pretty good, without any cracling...

If someone knows how to cure that problem, please anwser me.

PS. I've installed two .cab files for HTC Tornado, that were supposed to improve something (i don't remember what). Maybe whole problem si caused by them?

Regards, robs.
