1. Choosing and Attaching Eartips

The ER3XR comes with an assorted eartip pack to ensure optimal fit and noise isolation. Select the eartips that provide the best seal and comfort for your ears. Proper fit is crucial for achieving the intended sound quality and noise isolation.

• Triple-Flange Eartips: These provide the deepest insertion and highest level of noise isolation (up to 42 dB). Insert them deeply into the ear canal for the best performance.
• 폼 이어팁: Compress the foam tips before inserting them into your ear canal. Hold them in place until they expand to create a seal. These also offer excellent isolation.

2. 케이블 연결

The ER3XR features user-replaceable 4ft reinforced detachable cables with MMCX connectors. Align the connectors on the cable with the earphone bodies and push firmly until they click into place. Ensure the left (L) and right (R) indicators on the earphones match the corresponding cable sides.

3. 이어폰 삽입

For optimal sound and isolation, the earphones must be inserted deeply into the ear canal. Gently pull your earlobe up and back to straighten the ear canal, then slowly insert the earphone until a comfortable, secure seal is achieved. You should notice a significant reduction in ambient noise.

Connect the 3.5mm gold-plated stereo plug to your audio device's headphone jack. The ER3XR is compatible with a wide range of devices including laptops, desktops, tablets, smartphones, smart speakers, and televisions.

Volume Control and Safety

Adjust the volume using your audio device's controls. Due to the high noise isolation, you may find that lower volume settings are sufficient. Avoid listening at excessively high volumes for prolonged periods to prevent hearing damage. The earphones have a maximum output of 120 dB.

Cleaning the Earphones

Regular cleaning of your ER3XR earphones and eartips is recommended to maintain hygiene and optimal sound quality. Use a soft, dry cloth to wipe the earphone bodies. For eartips, remove them from the earphones and clean with mild soap and water, then rinse thoroughly and allow to air dry completely before reattaching.

케이블 관리

While the cables are reinforced and detachable, avoid sharp bends or excessive pulling to prolong their lifespan. If a cable becomes damaged, it can be replaced due to the MMCX connectors.
