I have 2 different wired headsets and a 2.5 mm adapter and although the iPhone recognizes I have headphones, the mic isnt working. Ive plugged and unplugged it, turned off the bluetooth settings, restarted it...all to no avail. HELP! CA handsfree law just went into affect and I dont want a bluetooth!

iPhone, Mac OS X (10.4.7)

    Can you tell if the headphone jack is all the way inserted? Since there is a recess in the iPhone jack, you may not have the male end all the way in. The plastic jacket around the base of the male end may be preventing it from seating right. Just a thought.

    thank you but yes, i have 2 adapters actually - one goes from 2.5 mm to 3.5 mm and the other goes from 3.5 mm to recessed 3.5 mm. The adapters seem to be working fine because I can hear through the headphones just fine and the iPhone acknowledges they are plugged in...its just the mic that isnt working...on BOTH headsets!

    Have you tried the headphones that came with the iphone?

    If not, that will help determine of it is the phone or the adapter.

    Hey Maria,

    If you have a protective case on the iPhone, try testing without it. That way we can make sure the adapter is able to plug in correctly.

    Does the iPhone Stereo Headset's mic work correctly when its plugged into the adapter? If not the adapter may be causing the issue. If it does then then the other headset may be causing the issue.

    It sounds like you may need another headset or adapter. The Apple online store has iPhone accessories:

    again thanks! The adapter (3.5 mm to recessed 3.5 mm) works fine. The 2.5 mm to 3.5 mm works fine. Together, they work fine as headphones...i can use the headset with the iPod part of my iPhone. I assumed if I can hear thru the head phone, the adapter(s) are not the problem.

    I returned the headset to Best Buy today thinking the mute switch mightve been bad but a 2nd headset yielded the same result - audio thru the ears, no mic:(

    dont know what to do...

    I bet your adapter only has two 'rings' just like standard audio headphones do. These allow the headphones to deliver stereo sound. The iPhone headset has a third ring that allows it to do a microphone in addition to the stereo sound. If you adapter only has two rings, then it won't allow a microphone to work.

    I am looking for the same type of adapter, as I hate BT headsets...

    I'm in the same, rapidly growing, club. I don't like Bluetooth earsets, I have some excellent Shure 2.5 mm earsets (headsets, earphones, etc) I'd like to use.

    From past experience I know a lot of cheap 2.5/3.5 adapters absolutely won't work. I'm hoping Griffin or a like vendor will put something out (their web site is broken this am). In the meanwhile I'll look for something I can test at a store.

    There's market confusion at the moment with the quite different iPhone 1.0 adapters, but I hope things will straighten out quickly. If you find anything that works please post details here, I'll track the feed for this thread.

    I've found one or two credible adapters -- but demand is high. Vendors are selling them for $16 instead of the usual $4. No Griffin or other reputable product yet.

    Don't get confused by the endless adapters for connecting a 3.5 mm stereo headphone to a 2.5 mm phone jack, or for getting a 3.5 mm stereo headphone to fit in the iPhone 1.0 3.5 mm recessed jack.

    We need to connect a mono 2.5 mm earset to the iPhone 2.0 3.5 mm jack.

    This one claims to work with iPhone 1:


    It's fits the iPhone 1 recessed jack, but it also claims to fit a Blackberry Curve. I might give it a try, though my experience with similar connectors has been very poor.

    Has anyone tried this one? Anyone know if this works with a headset, both sound and microphone?

    I'll know within a week, so if you don't hear before then check back. I placed my order yesterday for two adapters for $8 each (see link in my prior message) and $6 shipping from 1800mobile.

    I'm sure they'll be vastly cheaper in a few months, but there's going to be a crushing demand in the near term. I've seen them sold for $17 without shipping already!

    I bought two 3.5mm to 2.5mm headset (earset) adapters from 1800mobiles.com part number APLIPHONEHFA2. They work, I can now use my favorite Shure easets with my iPhone 2. They're very slender, so they don't add significant bulk to the earsets. $8 each, white in the picture, black when I got 'em.

    If you search on this part number you will find multiple vendors, probably all the same company. 1800mobiles wasn't bad, but they sent me an invalid tracking number and didn't answer customer support emails.

    Here's one vendor's description:

    Apple iPhone 3.5mm-2.5mm Headset Adapter APLIPHONEHFA2
    Apple iPhone 2.5mm stereo headset adapter for the iPhone 3.5mm recessed stereo audio jack, fits Apple iPhone and Rim 8300 Curve cell phone models by converting the jack to a standard 2.5mm jack for use with any universal headset such as Jabra or Plantroinics or Shure.

    * Apple iPhone Adapter fits the recessed Apple iPhone audio jack, since the Apple iPhone headset port is deeper that the outside casing. This Apple iPhone headset adapter is custom designed to makes it easy and convenient for you to connect your standard 2.5 mm monoi headsets into the iPhone's recessed headset port.

    This sounds great - just what I'm looking for. You mentioned that they work with the iPhone 2, but you didn't mention if the microphone part works, too. Does it? I'm looking to use just a standard monaural headset for talking on the phone (not stereo or really for listening to music) and with the use of a 2.5mm female end to a 3.5mm male end adapter, plug that into the iPhone 2. Is that what this product is doing for you?

    Thanks a lot,
