Do the Tiger Eyes ear phone work with all mobile phones?
This model is designed especially for iPhone use, however you can use them to any MP3 players with 3.5mm plug as long as they have the same PIN definition. JayBird recommends not using the Tiger Eyes with other mobile phones as it may result in poor audio performance. To be able to use the Tiger Eyes on the Nokia N97 for example, the headphones need to have a Nokia control IC. As a troubleshooting step try using the Apple iPhone earphones with the Nokia N97. You will likely encounter similar performance issues.
