To remove your earphone cable pull the cable

in the direction parallel to the earphone

connector. Avoid pulling the cable at an

4

angle, as this can damage the mmcx connectors

of the cable and/or the earphones.

5

Take care not to drop your earphones. Each

Campfire Audio earphone holds a sensitive

and finely tuned transducer. Sudden shocks

or impact to the shell can potentially cause

damage or alter the performance of the

earphone’s transducer.

Damage to the earphone transducers (drivers)

are not covered under the earphone’s warran-

ty protection and are subject to a reasonable

fee for repair.

Take special care to keep the earphone

openings clear of debris and wax. Carefully

use the clearing tool included with your

earphones to remove build up from the

earphone. Take extra care not to push any

foreign objects into the canal of the

earphone openings. Avoid moisture build up

on the surface and in the interior of the

earphone body.

Opening the body of the earphone will damage

the seal of the shell and alter the precision

tuning of your earphone. Tampering, opening,

or altering the shell will void the warranty

of your earphone.

Note that extended listening periods at high

listening levels can negatively impact your

hearing over time. Please enjoy your

earphones responsibly.
