This software enhances wired headset button capabilities by allowing users to control track and FM channel switching, playback pause/resume, rewind/fast forward, and volume adjustments without needing to physically interact with the device.

One of the best things about Headset Button is that it works on devices from various manufacturers. If you're using an HTC, Glofiish or RoverPC device, you can take full advantage of its features. You can find a complete list of compatible devices on the Headset Button website.
What's more, Headset Button supports a number of third-party players, including TCPMP, Pocket Player, Pocket Music and Nitrogen, among others. You can find a complete list of supported players on the website as well.
The app is designed to recognize five different types of headset button presses: single, double, triple, long (press and hold) and double long (where the second press is long). You can assign a specific command to each press type. The last two press types are particularly useful for controlling commands that take longer, such as fast forwarding or rewinding.
If you receive a phone call, the wired headset button will work as usual, as set up by the manufacturer. Headset Button does not interfere with phone operations.
Fortunately, you can download a fully functioning trial version of Headset Button for free. If you find it helpful, you can purchase the full version to enjoy all its features.
