I'm looking for a headphone with a 6mm adapter. I have a lenovo thinkpad and it doesn't recognize regular headphones with 3.5mm adapters. I've called the tech support and they told me to get a 6mm one. They said Apple and Sony make such headphones. But couldn't give me exactly one name. So I want to buy one, but don't know it's name (they don't know too). Anybody knows?
i can't think of any computer that would use a 1/4 inch TRS plug - certainly not thinkpads. You can get an adaptor at almost any electronics part store. Quite a few medium-high end headphones come with them as well.
I do believe the newer thinkpads support a 3.5 mm TRRS plug for headphone and mic however.
EDIT: and.. while its not exactly the answer - apparently on windows 7 thinkpads with the combo trrs jacks, you can use a normal headphone by setting your headphones as the default device - plug in your headphones rightclick on the mixer icon, select playback devices, and set your headphones as the default device. It will switch back to the speakers as default when you unplug. HOWEVER, if you want to deactivate the headset again, you have to do it with headphones plugged in.
Those would be headphones with a "1/4 inch" plug -- the same plug that plugs into your electric guitar or the headphone jack on your dad's old stereo set. Converters between the 3.5mm and this size are readily available at a Radio Shack, et al, though they would likely be called "1/8 inch to 1/4 inch" converters.
Keep in mind that "3.5mm" used to be 1/8 inch -- both 3.5mm and 6mm are approximations to the real "nominal" sizes. (6.5mm would be a closer approximation to 1/4 inch, but it matters not given that there must be some "slop" in the measurement anyway to allow for ease of insertion/removal, and there are no other standard sizes in the same range that might create confusion.)
There is also a (relatively rare) 3/16 inch standard that would amount to about 5mm, and a 3/32 inch standard which is the same as the 2.5mm connector used on some phones.
They're called headphones. :)
You're specifically refering to the larger audio connector that used to be common and now is generally only found on pro-audio systems such as sound boards and the like.
Go to Walmart and get an adapter. It just looks like a larger audio connector with a smaller hole in the back. This will allow you to use your own current headphones with their 3.5mm connector in the 6mm hole.
UPDATE: They are specifically called 6mm Audio Connectors ("Connectors" can also be replaced with "Jacks", though some would argue the Jack is what the Connector plugs in to). As opposed to what you currently have, which is a 3.5mm Audio Connector. It's pretty much the same thing as a USB, mini USB, and micro USB. It's the same connector just in a different size.
6MM isn't very common, and I'm kinda wondering what sort of laptop design you have that incorporates a 6mm jack. Once Walkmen and portable CD players came into common usage, the 3.5mm Audio Connector fits much more easily in the smaller designs.
UPDATE: Wikipedia calls them TRS connectors: http://en.wikipedia.org/wiki/TRS_connector and now I know why I didn't recognize "6mm" right off the bat. I'm used to calling them "quarter inch audio connectors" because they're technically 6.38mm, or 1/4in, in diameter.
