I'm offering a set of transmitters and receivers. I'm selling them because I've used them less since acquiring a different model. There is a slight amount of noise, but it's at a level that doesn't affect use. This is a direct sale of the item as is. Included accessories: 3.5mm stereo cable, Cannon female to 3.5mm stereo cable SONY UTX-P03 and UTX-B03 wireless system. - Model: UTX-P03 - Model: UTX-B03 - Brand: SONY - Connection type: Wireless Thank you for looking.
