Did you know that you can use a corded headset with a 2.5mm plug with your iPhone? It’s probably easier than you think!
Headsets designed for land-line phones or older style mobile phones are frequently built with 2.5mm plugs. iPhones, however, only have the 3.5mm sockets meant for stereo headsets. This can be a special problem for disabled users who may only find one headset that exists that really works for them – if that headset has a 2.5mm plug you can be in trouble.
There are “standard” 2.5mm to 3.5mm adapters available but many won’t work properly with iPhones and headsets – a fairly complex combination. Often these standard adapters work fine for the speaker but not the microphone, or let both the speaker and microphone work but not the “answer” button on the headset.
But there is a solution!
It’s a slightly contradictory solution – you need to buy what Apple calls the Apple iPhone TTY Adapter.
This adapter is designed by Apple to allow Deaf and hearing impaired telephone typewriter users to hook their existing TTY devices to an iPhone, but as a happy side effect it has the ability to hook almost any headset with a 2.5mm plug to your iPhone.
Buyers do need to beware slightly – this solution is not endorsed by Apple as a general solution for 2.5mm headsets, so they will not promise that it will work with your headset. But there are many 5-star ratings on the Apple Store from happy headset users who have used this solution and highly recommend it.
Headsets specifically recommended as functioning well with this adapter by Apple Store reviewers included:
- Hatis Freedom Mach II headset (works directly with hearing aids)
- Bang & Olufsen Earset 1
- Plantronics M114 headset
Several other reviewers did not specify the headset they used though.
