Re: Wireless Headphones with Hum sound?

Thanks guys; the set uses 2 1,5 volts small batteries and it has power supply input of 4.5 vdc, i tried a few of good dc power supplies, and one of them is a great power supply that has 1.5 to 12v dc with switch that i've got when Radio Shack was still opened and it's the best power regulated supply that i ever have, i suspect that i used a different power outlet of the TV, maybe that's the issue ,i'll check after christmas, i have it wrapped up to give wife for Christmas,

Re: Wireless Headphones with Hum sound?

Not knowing what type of power supply you tried makes it hard to tell whats wrong, Was it one of those adaptors with the voltage switch? what was the current rating of the adaptors you tried?
Link points to the PYLE model: PHPW5

it also has a few radio FM channels that don't do that only with audio source

I believe the fm radio receiver is in the headset and not in the base. You could also dissconnect the tv input to the base and see if the hum is still there, if the humis still there but not there while on batteries, the hum must be from the adaptor

Are you using 4.5V regulated power supply?
Does it use three 1.5V batteries?
