Before getting into more complex solutions, the first thing you should do is check the sound settings from the mobile phone, because many failures are simply due to the volume not being set correctly or the audio being sent to another device.

• Make sure the multimedia volume It's loud enough. To check this, play any audio (music, video, voice note) and increase the volume using the side buttons. Remember that the volume of calls and notifications It is different from multimedia volume.
• Tap the icon or the three dots on the volume control to see where the sound is playingEven if you have headphones connected, your phone may be sending audio to a Bluetooth speaker or other nearby device.
• Check if the mobile is connected to another device Bluetooth audioTo do this, turn off Bluetooth for a few seconds, turn it back on, and check the list of paired devices to make sure your headphones are the primary output.
• If you use Bluetooth headsetsCheck that they are actually paired with the phone and not with another nearby device (another mobile phone, tablet, laptop, smart TV, etc.). Ignore or disconnect any that may be interfering.
• In the accessibility settings of your mobile phone, check the audio balance between left and right channelsIf the bar is shifted to one side, you might only hear one earbud or perceive the other as sounding very quiet.

Check the physical condition of the connector and headphones

If you use wired headphonesThe problem may lie in the jack plugThis is where the wear and tear from daily use is most noticeable, either at the USB-C port (if connected via that port) or on the headphone cable itself.

• Try using other headphones that you know work well. This will help you determine if the problem lies with the... accessory or on your mobile phone. If other headphones work without a problem, your current model may have a broken cable or a damaged connector.
• Visually inspect the headphone jack or USB-C connector. If it's bent, Presents cracks If the connection is forced, it may not be good, which is why the sound cuts out or nothing is heard.
• Insert the headphone jack into the phone's port and twist it gently, without applying force. If the sound appears... intermittent Moving it is a clear sign of poor physical connection or damaged internal cable.
• Check if the cable has zones peeled, very folded or twistedespecially near the connector and the headphones. These areas often break internally, causing one side to stop working or the audio to cut out with the slightest movement.

Clean the headphone port (jack or USB-C)

Dust, lint from my pocket, and the dirt They can accumulate in the 3,5 mm jack or USB-C port, preventing a proper connection between the phone and the headphones. This is one of the most frequent causes when the phone detects headphones connected but There is no sound or they disconnect with slight movements.

• Use a small spray of compressed air Or use a blower bulb to expel the dust accumulated inside the connector. Do this with the phone turned off and using short bursts of air, without holding the nozzle too close to the port.
• Insert a wooden toothpick with cotton soaked in isopropyl alcohol To carefully clean the inside of the connector. Isopropyl alcohol evaporates quickly and is less harsh than other household cleaning liquids.
• Avoid using metal objects (such as pins or paper clips) that could damage the port contacts or cause a short circuit. If you're inexperienced, it's best to stick to compressed air and wooden sticks.

Specific solutions for Bluetooth headphones

When problems arise with Bluetooth headsetsIn addition to the above, you should take into account factors such as battery charge, distance, interference, or even the audio codec used between the mobile phone and the headphones.

• Check the battery in your headphonesIf the battery is low, disconnections, sound cuts, or pairing failures may occur. Charge them fully and also check that the cable or charging base they work right.
• Check the Bluetooth connectionMake sure the headphones are in pairing mode, your phone's Bluetooth is turned on, and you select them from the list of available devices. If they were already paired, remove ("forget") the device and pair them again from scratch.
• Avoid interferenceToo many Bluetooth devices or Wi-Fi networks nearby can cause dropouts. Move closer to your phone, turn off other nearby devices, and see if the connection is more stable.
• On Android phones with developer optionsyou can change the Bluetooth codec (for example, between SBC, AAC, aptX, or LDAC). Sometimes, using a simpler codec improves stability with certain headphones.
