Connecting to a Device
- Locate the 3.5mm audio jack on your audio device (smartphone, tablet, computer, MP3 player, etc.).
- Insert the 3.5mm plug of the earphones firmly into the audio jack until it clicks into place.
Wearing the Earphones
The RP-HJE125 earphones feature an ErgoFit design for comfortable and secure placement. Proper fit is crucial for optimal sound quality and noise isolation.
- Select the Correct Ear Tip Size: The earphones come with multiple sizes of silicone ear tips. Experiment to find the size that creates a snug seal in your ear canal without causing discomfort. A good seal enhances bass response and blocks external noise.
- Insert the Earphones: Gently insert each earphone into its respective ear canal. The L (left) earphone goes into your left ear, and the R (right) earphone goes into your right ear.
- Adjust for Comfort: Rotate the earphone slightly until it feels secure and comfortable. The ErgoFit design is intended to conform to the natural curve of your ear.
