I just found out that when I press the mic button on the connector cord from the phones, I get the missing speech and no distortion. I guess I will either have to get a different cord without the buttons on, or place a small bulldog clip on the button to hold it in! Anyone else throw any light as to why this is?
I have some JBL s500 headphones and I am trying to connect them to my Yamaha receiver. The cord from the headphones has a smaller (2.5mm?) connector to the phones, with a 2 ring plug, then a 3.5mm 3 ring plug that goes into whatever I need. I have tried plugging it into one of my TV sets with an extension cord with 1/4" 2 ring adapters, but bad distortion, especially on speech. I tried plugging it directly into the TV itself on the 3.5mm socket and it works fine, but need an extension. Then i tried it in my other setup which has the Yamaha receiver with a regular 1/4" jack socket, and same distortion problems with the 1/4" jack adapter. I wonder if I just need a better quality adapter, or if there is a non-compatibility issue with the 3 ring headphone jack and the 2 ring adapter?
