Important Notes: 1. Before placing an order, buyers must first determine whether the device noise is caused by external signal interference. If the noise stems from unstable signals due to hardware faults, faulty cables, or loose connections, this product will be ineffective for such issues. Please exercise caution when ordering. 2. When using the product, refer to the cable diameter and product dimensions in the product diagram to select the most suitable size. Ensure full contact between the cable and the product's inner surface to achieve effective external signal shielding. 3. To enhance the product's interference shielding and noise reduction capabilities, install additional units sequentially along the same cable until interference is fully shielded and noise eliminated. 4. For finer cables, select a product with a slightly larger inner diameter. Wrap the cable around it once to increase the contact area between the cable and the product.
