A man asked:
What is the difference between the Music Links and the T-links other than the T-links have a built-in microphone and use a different sized plug?
The big difference is in how the plug is wired. The Music Links are wired exactly the same way stereo earbuds/earphones are wired—one channel to the tip, second channel to the ring and ground to the shank.
The T-Links, because of the microphone are wired with both ears to the tip, microphone to the ring (or vice versa, I don’t really know) and ground to the shank.
Thus, the Music Links work with all regular audio device jacks (3.5 mm), and they let you can hear in true stereo. The T-links only work properly in headset phone jacks (2.5 mm), and you hear dual mono.
If you used an adapter so you could plug the T-links into an audio jack, you’d hear one stereo channel in both ears and the other stereo channel would go to the microphone (which wouldn’t do it much good at all!)
As far as the ear hooks themselves go, they are exactly the same for both units.
