Setup

1. Charging the Device

Before initial use, fully charge your ISOtunes PRO headphones. Connect the supplied USB charging cable to the charging port on the inline control module and plug the other end into a USB power source. The LED indicator on the control module will show charging status.

• Charging Time: Approximately 10 hours for a full charge.
• Battery Life: Up to 10+ hours of music playback/talk time, 240 hours standby time.

2. Selecting and Fitting Eartips

Proper eartip selection and fit are crucial for optimal noise reduction and sound quality. Experiment with the included foam and silicone eartips to find the best fit for your ears.

1. Foam Eartips: Roll the foam eartip into a thin, creased cylinder. Pull up on your auricle (outer ear) to straighten the ear canal. Insert the compressed eartip deep into your ear canal and hold it in place until it expands and creates a seal.
2. Silicone Eartips: Gently insert the silicone eartip into your ear canal until a comfortable seal is achieved.

The custom-fit memory wires should be gently molded to fit around the back of your ears, ensuring the eartips remain securely in place during active use.

4. Select "ISOtunes PRO" from the list. Once connected, the LED indicator will flash blue periodically.
