The Fishbone TRRS Adapter is AVID’s innovative answer to pin breakage issues in audio devices. Designed with a flexible, ribbed “spine,” it bends and rotates in reaction to strain, allowing the adapter plug to slip free instead of damaging internal jacks. This helps reduce tech downtime and extends device life in school settings. How It Works Inspired by a swimming fish’s motion, the Fishbone flexes laterally across its ribs while twisting inside a jack. When pressure is applied (e.g., a student yanks a cord), the adapter disengages before bending or shearing the device’s internal pin contact. It’s a targeted, low‑cost solution for reducing hardware failures in classroom audio setups. Key Benefits Protects expensive audio devices from pin damage Flexible “breakaway” design reduces repair costs and downtime Rotates in the jack to align with pull direction Simple, compact, low‑cost add-on accessory Complies with CPSIA & TPCH safety regulations Usage & Installation Plug Fishbone adapter into device’s TRRS jack before connecting your TRRS headphone cable. Ensure a snug fit — it should seat fully without wobble. Ideal for student environments where cords may get pulled or tripped over. If repeatedly dislodged, inspect for bent plugs or misalignment. Care & Quality Each Fishbone adapter undergoes a QA inspection before shipping. Avoid excessive twisting or bending beyond normal usage. Complies with applicable CPSIA and TPCH regulations for safety. :contentReference[oaicite:0]{index=0}
