Setup

1. Attaching the Cable

   The earphones feature a detachable 2-pin 0.78mm interface. Carefully align the pins on the cable with the receptacles on each earphone unit. Push firmly until the cable is securely connected. Ensure the left (L) and right (R) indicators on the cable match the respective earphone units.

2. Selecting Ear Tips

   Choose the silicone ear tips (S, M, L) that provide the most comfortable and secure fit for your ears. A proper seal is crucial for optimal sound quality and noise cancellation. Experiment with different sizes to find the best fit.

3. Wearing the Earphones

   The earphones are designed for an ergonomic, over-ear fit with a pre-molded wrap-around cable. Gently insert the earphone into your ear canal and loop the cable over your ear for a secure and comfortable placement. This design helps keep the earphones stable during movement and reduces microphonics.
