1. Introduction
This manual provides instructions for the installation and maintenance of your YDYBZB Memory Foam Ear Pads, designed as a replacement for SMS Audio Street by 50 Headset headphones. These ear pads are crafted from high-quality velvet leather and memory foam to enhance comfort and listening experience.
2. Installation Guide
Follow these steps to replace the ear pads on your SMS Audio Street by 50 Headset. Ensure the headset is powered off before beginning the installation process.
- Remove Existing Ear Pads: Gently peel off the old ear pads from the headphone cups. They are typically held in place by a thin rim or adhesive. Take care not to damage the headphone's speaker or internal components.
- Prepare New Ear Pads: Take one of the new YDYBZB Memory Foam Ear Pads. Observe the back side, which features a flexible rim designed to fit around the headphone cup.
- Align and Attach: Align the new ear pad with the headphone cup. Start by hooking a section of the ear pad's rim onto the edge of the headphone cup.
- Secure the Ear Pad: Carefully work your way around the headphone cup, stretching the ear pad's rim over the entire edge until it is fully seated and secure. Ensure there are no gaps or loose sections.
- Repeat for Second Ear Pad: Follow the same procedure for the other headphone cup.

3. Usage
These ear pads are designed to provide comfort and improve sound isolation during normal use of your SMS Audio Street by 50 Headset. Once installed correctly, they require no further active operation. The memory foam conforms to your ears for extended comfortable listening.
4. Care and Maintenance
Proper care will extend the lifespan of your ear pads:
- Cleaning: Gently wipe the surface of the ear pads with a soft, damp cloth. Avoid using harsh chemicals, abrasive cleaners, or excessive moisture, as these can damage the material.
- Storage: When not in use, store your headphones in a clean, dry environment away from direct sunlight and extreme temperatures.
- Avoid Punctures: Keep sharp objects away from the ear pads to prevent tears or punctures in the velvet leather.
5. Troubleshooting
If you encounter any issues with your replacement ear pads, consider the following:
- Ear Pads Do Not Fit: Verify that your headphones are indeed the SMS Audio Street by 50 Headset model. These ear pads are specifically designed for this model. Re-check the installation steps to ensure the rim is fully seated around the headphone cup.
- Discomfort After Installation: Ensure the ear pads are installed evenly and not twisted. Allow a short period for the memory foam to conform to your ears. If discomfort persists, re-install the ear pads.
- Reduced Sound Quality: Ensure the ear pads are fully sealed around the headphone cups. Gaps can affect sound isolation and bass response.
