3.5mm Male to 2.5mm Female Adapter?

Question

When fully, plugged in, there should be audio output(sound/music/etc.) coming out from both the left and right speaker/headphone/etc. right?

The reason I ask is because I have one that, when used, doesn't have audio output from both the left and right when it's fully plugged in. If I moved the adapter out of the phone a little, in a certain place, then there's audio from both sides. This is a replacement b/c the 1st one did this too.

the product description doesn't say whether or not its stereo or not. It's from Meritline.Com. This is annoying b/c when if I get it to work w/ audio output from both sides, and it slightly moves, then there's sound from only one side or none then I have to move it again.

So nothing can really be moved to keep the audio output coming from both sides unless it's very carefully.

The product page:

It has 2 bands/rings. I'm guessing w/ phones, the 3 bands would be for listening and the microphone, but aren't the rings/bands insulators? From what I know, the metal tip is the left channel audio, the middle metal part is the right channel and the bottom is the ground.

The headphones I use don't have a microphone, they're just regular headphones for music, so shouldn't the adapter work?

The headphones I use have a 3.5mm jack, which is the purpose of the adapter. The headphones are stereo also.

The adapter is for standard 3.5mm headphones to be used on a phone that accepts 2.5mm headphones

Answer 1

what u describe and the web page match. that is a stereo plug.

does the headphone have the same configuration?
It could be just a mono headset.

is the headphone the same size as the adapter plug?
maybe u don't need the adapter.
