How to use
To use the 4World Tangzu Waner 2, simply insert the 4.4mm plug into the balanced output port of your compatible audio player, amplifier, or DAC. Ensure the earpieces are inserted firmly into the ear canal to achieve the best seal, which is essential for optimal bass response and sound isolation. Adjust the cable position around your ears to ensure a secure fit that prevents the cable from pulling on the earpieces during movement.
What to consider before purchase
Verify that your audio source device features a 4.4mm balanced output
Consider if you require a microphone, as this model does not include one
Ensure the in-ear fit is suitable for your personal comfort preferences
Usage recommendations
For the best audio performance, ensure that your source files are of high quality, such as FLAC or other lossless formats. Always store the headphones in a protective case when not in use to prevent cable tangling and damage to the connector.
