Key benefits Reduces electromagnetic interference (EMI) and cable noise to improve signal integrity for connected devices. Quick, tool-free installation with a secure double-lock snap that stays closed during normal use. Durable construction for long-term reliability in home and office environments. What it does Ferrite ring cores act as noise suppressors on cables, helping to filter high-frequency interference and stabilize signals for USB, mouse, keyboard and headphone connections. Designed to lower unwanted noise on multiple devices without changing cable routing or hardware. Performance and materials Magnetic saturation induction intensity: 400 Initial magnetic permeability: 850–2000 Ferrite core housed in a sturdy plastic case for impact resistance and ease of handling Density: 4.9 g/cm3 Curie temperature: 120 °C Compatibility and size Inner diameter: 13 mm — fits most standard USB, mouse, keyboard and headphone cables Suitable for both home and office setups across a variety of cable types Installation and use Snap-on double lock mechanism allows fast attachment or removal without tools Compact design keeps cables tidy while providing continuous suppression during use Typical applications Home office: Reduce interference on USB webcams, headsets and keyboards for clearer video calls and stable peripherals. Gaming and audio: Clip onto headset, controller or USB cables to minimize audio hiss and signal disruptions during gameplay or streaming. Workstations and recording: Improve signal integrity on peripherals and short USB connections used in content creation or live conferencing. What makes it stand out Combines proven ferrite material properties (high permeability and defined saturation) with a robust plastic housing and a reliable snap-lock for easy, repeatable use. Practical size and broad compatibility make it a simple, effective addition to multiple devices without modification. Package notes Ferrite ring cores delivered as snap-on clips; no tools required for installation.
