JLab JBuds Pro In-Ear Headphones - Black

If there is no sound coming from your headphones/earbuds, please check the following: 

• Loose connection: Ensure the 3.5mm jack is fully inserted into the headphone port.
• Wrong port: Double-check that you're not plugging into a microphone or line-in port.
• Device volume: Make sure the volume is turned up and not muted.
• Try another device: Test the headphones/earbuds on a different phone, tablet, or computer to isolate the issue.

If there is sound only coming from one side of your headphones/earbuds, please check the following: 

• Damaged cable: Wiggle the cable gently—if sound cuts in and out, the wire may be frayed internally.
• Partial plug-in: Make sure the jack is fully inserted until it clicks.
• Audio balance settings: On some devices, audio balance may be shifted to one side. Check your sound settings.

If the sound is distorted or crackling on your headphones/earbuds, please check the following: 

• Dirty jack: Clean the headphone plug and device port with a soft cloth or compressed air.
• Cable damage: Internal wire damage can cause intermittent or distorted sound.
• Low-quality audio source: Try a different app or file to rule out poor audio quality.
