As a low vision Windows 7 and Mac Snow Leopard user, I access computers via a screen reader (JAWS) for Windows 7 and (VoiceOver) for Mac Snow Leopard.
I also happen to be a very satisfied user of iPhone 3GS.
Included with the iPhone 3GS, at the time of purchase, is a very nice set of Apple branded stereo earphones with inline 3-button remote control and microphone. This included headset can be used to remotely control iPhone 3GS volume level, dialing feature, and iPod App.
Since the release of iPhone 3GS, I have damaged the microphone on at least three sets of these headsets by various sundry accidents including getting the microphone wet.
The other day, while opening yet another pair of Apple iPhone 3GS earphones, I decided to attach the older pair to my MacBook Pro.
What do you think I discovered? You’re right! The inline remote control acts just like it does on my iPhone 3GS; that is, the volume buttons work to change the volume level of the MacBook Pro and the middle button will open iTunes. When iTunes is playing media, the headset inline remote control functions to navigate the playback just as it does on the iPhone 3GS.
As a bonus, even when running Windows 7 in VM Ware’s Fusion, the inline remote volume buttons continue to function normally.
So, go ahead and shove that iPhone 3GS 3-button inline remote control headset with Microphone, attached to your MacBook Pro, in your ear.
