Frequently Asked Questions - 501s JPL
How do I connect the JPL 501s headphones to my device?
Simply plug the 3.5mm audio jack into the headphone port of your device (smartphone, tablet, laptop, etc.). Make sure the connection is secure. No additional drivers or batteries are required.
How should I clean the headphones?
Use a soft, dry microfiber cloth to gently wipe the ear cups and headband. For stubborn dirt, slightly dampen the cloth with water (not wet) and wipe. Avoid using chemical cleaners, alcohol, or abrasive materials as they may damage the leatherette finish.

How do I adjust the headband for a comfortable fit?
Hold the ear cups and gently slide the headband extenders up or down until the headphones fit snugly over your ears. The headband should rest comfortably on your head without excessive pressure. Make sure both sides are adjusted equally for balanced fit.
Are the JPL 501s headphones compatible with smartphones?

How should I store the headphones when not in use?
Fold the headphones using the hinge mechanism and store them in a dry, cool place. Avoid leaving them in direct sunlight or high temperatures. Use a protective pouch if available to prevent scratches and dust accumulation.
Can I replace the ear pads?

The standard warranty is 1 year from the date of purchase. It covers manufacturing defects under normal use. Proof of purchase (receipt) is required. For warranty claims, contact JPL customer support or your retailer.
Are these headphones foldable for easy portability?
