Reviews for Apple iPhone TTY Adapter

One of my frustrations with the iPhone was the lack of plug in telephone headsets. This solves the problem. I am using it with a noise cancelling Plantronics headset and am as happy as can be. Voice and sound quality are both better than with any Bluetooth unit and as good or better than holding the telephone up to your ear.

Note that the three-contact adapters sold at Radio Shack and other places don't work. I am not sure why, but you need to get this four-contact TTY plug for good voice quality. (see the photo and compare to the others to see what I am talking about).

This is the ONLY adapter that will allow you to use your regular cell phone wired hands free headsets with the iPhone. It also allows you to use your house phone wired headset with the iPhone. Those use the 2.5 mm pin, and this adapter plugs that into the 3.5 mm that the iPhone uses. But BEWARE, this is the ONLY adapter that will work in the iPhone jack. The ones they sell in Radio Shack look similar, but do NOT work, as they only have two sections on the pin that goes in the iPhone, not the three that are required. The same thing is true of the other adapters you find elsewhere, they just don't work in the iPhone. Save yourself the trouble and just buy this Apple adapter. It's a shame that Apple doesn't advertise this adapter. Apple calls it the TTY adapter, and it does work for TTY (it's a deaf person typing machine), but it is also the ONLY solution for using a wired handsfree headset with the iPhone, and Apple should TELL people that!

This adapter allowed me to use older headsets that are 2.5mm. It is very compact, much better than a non-apple product I had before.

I purchased a iPhone 3G and this TTY adapter after reading the reviews about this allowing me to use my existing 2.5mm wired headset with my iPhone.

I will report that it does work. However, my voice is so soft that the party on the receiving end of the call can only hear me if they turn there volume all the way up and are in a very quite environment. If I unplug the headset and talk on the phone directly they can hear me loud and clear.

This is using the exact same headset that I used on my previous Motorola flip phone that sounded excellent. So it obviously and adapter/phone issue.

It's a shame that no one feels the need to create a quality wired headset for making phone calls on the iPhone. I could care less about listening to music so a two ear approach is overkill and could be down right dangerous. If I'm driving while using my headset it's important to be able to hear other nosies outside of the context of a phone call. Perhaps that fire truck that's about to blow through the red light and t-bone you if you don't stop on green?

I have yet to find a blue tooth headset that does not sacrifice sound and voice quality for the sake of convenience or to look cool.

Call me old fashioned but the "killer" app on any mobile phone should still be a phone!

I have had the Plantronics M114 head set for a couple years and used it with a Motorola 120t cellular phone with good results. This iPhone TTY adapter allows me to continue to use this headset. I use this combination for work and need both good quality sound to and from the headset. I am very pleased with the results. With the head set microphone set to most sensitive and the head phone volume set to maximum the sound levels are good, for me and for the person I am talking with, with some sound adjustment still available on the iPhone. My iPhone is a 3GS.

I just bought this along with a plantronics corded headset. The microphone does not work with the adapter, only the audio on my end. What's going on? Oddly enough, it works on my blackberry. I hope it works with my new 4S that is coming tomorrow. Otherwise, It's going back to Apple and I will be very upset.
