Setup

Follow these steps to set up your AIWA ESTM-101 earphones:

Choose the Right Ear-tips: Select the silicone ear-tips (S, M, or L) that provide the most comfortable and secure fit for your ears. A good seal is crucial for optimal sound quality and bass response. Gently pull off the pre-installed ear-tips and push on the desired size.
Connect to Your Device: Insert the 3.5mm audio jack firmly into the headphone port of your smartphone, tablet, laptop, or any compatible audio device. Ensure the connection is secure.
Proper Ear Placement: Gently insert the earphone units into your ear canals. The 'L' (left) and 'R' (right) markings on the earphone units indicate the correct orientation. Adjust them until they feel snug and comfortable.
Cable Management: Use the included cable clip to attach the cable to your clothing, reducing cable sway and microphonics (noise from cable movement). Use the Velcro belt to keep the cable tidy when not in use or for storage.

Maintenance

Proper care will extend the life and performance of your earphones:

Cleaning Earphone Units and Ear-tips: Regularly clean the earphone units and silicone ear-tips with a soft, dry, lint-free cloth. For ear-tips, you may gently remove them and wash with mild soap and water, ensuring they are completely dry before reattaching. Do not use harsh chemicals or abrasive materials.
Cable Care: The braided cable is designed to be tangle-free. Avoid excessive pulling, bending, or twisting of the cable, especially near the connectors. When storing, use the provided Velcro belt to keep the cable neatly coiled.
Storage: When not in use, store your earphones in the provided cloth pouch to protect them from dust, dirt, and physical damage. Avoid storing them in extreme temperatures or high humidity.
Water Resistance: The earphones are rated as 'Water Resistant'. This means they can withstand light splashes or sweat. They are not designed for submersion in water or exposure to heavy rain. Avoid using them during swimming or showering.
