SoundSlide is a small, physical accessory that connects via USB-C, providing a tactile way to control laptop volume, bypassing complicated keyboard shortcuts.
The flat capacitive surface of SoundSlide translates sliding gestures into volume adjustments, while a simple tap mutes or unmutes, enhancing user experience.
Providing easy access to volume control, SoundSlide addresses the inconsistency of volume control keys across laptops, making it easier for users to manage sound.
Designed for convenience, SoundSlide works on Windows, macOS, and Linux, ensuring accessibility without needing setup, while allowing customization of controls.
