2.3 Choosing and Installing Ear Tips

Selecting the correct ear tips is crucial for optimal sound quality and comfort. Experiment with the included ear tips to find the best fit for your ears:

  1. Gently remove the pre-installed ear tips from the earphone nozzles.
  2. Select a pair of ear tips that feel comfortable and provide a good seal in your ear canal. A proper seal enhances bass response and passive noise isolation.
  3. Carefully push the chosen ear tips onto the earphone nozzles until they are firmly attached.

2.4 Wearing the Earphones

The S08 earphones are designed to be worn with the cable over your ear for a secure and comfortable fit:

  1. Insert the earphone unit into your ear canal.
  2. Loop the cable over the top of your ear, guiding it downwards behind your ear. The pre-formed ear hooks on the cable help secure the fit.
  3. Adjust the earphones until they feel snug and comfortable, ensuring a good seal.

Regular cleaning helps maintain sound quality and hygiene:

  • Ear Tips: Remove ear tips and clean them with mild soap and water. Rinse thoroughly and allow them to dry completely before reattaching.

4.2 Cable Care

To prolong the life of your cable:
