It's pretty simple when you use a cable to plug into your mobile devices and your headphones.
How to determine if your headphones is 3.5mm or 2.5mm? It’s easy to test using your headphone’s cable and your smart phone.
It is 3.5mm if you can plug it in snuggly to the audio port on iPhones/iPads/android smart phones/android tablets.
Check both ends of the cable, one end into your headphones, and one end into your devices. It's 3.5mm if they are the same size. If one end is smaller than the other end, the smaller end is 2.5mm, choose this one.
The BTunes 3.5mm model is compatible for the following headphones (may not limited to these).
Note: ANC7b* is reported to work, but it's tilted a little outward and the mic is backward (see photos)
