The Audio-Technica ATH-M50x headphones are widely praised for their sound quality, build, and value. They’re a popular choice among audio professionals, content creators, and audiophiles alike. However, like any widely used piece of technology, the ATH-M50x is not immune to issues. One of the more common but frustrating problems users report is the presence of static or crackling sounds during use. This article explores the most likely causes of static and crackle issues on the ATH-M50x and provides proven solutions to help you restore your audio experience to its intended clarity.
Understanding Static and Crackling Noises
Before diving into causes and fixes, it’s important to define what users often describe as “static” or “crackle.” These terms generally refer to:
- Intermittent popping or clicking sounds.
- A constant hiss or buzz that overlays your audio.
- Unexplained audio cut-outs that jump back into normal levels with a popping sound.
These audible anomalies can result from a range of issues, from hardware defects and cabling problems to software conflicts. Because these headphones are wired and not wireless, it’s easier to isolate the source of the problem by eliminating multiple uncontrolled variables such as Bluetooth and battery interference.
Common Causes of Static and Crackle in ATH-M50x
1. Cable Issues
The ATH-M50x comes with three detachable cables: a coiled cable, a straight 3-meter cable, and a more portable 1.2-meter straight cable. While detachable cables are convenient, they introduce extra connection points that can wear down over time. The most common cable-related causes include:
- Worn-out cable connectors that may not firmly sit in the headphone jack or audio source.
- Internal wire damage due to repeated bending or pulling, particularly around the connectors.
- Dirt or debris in the plug or jack interfering with proper electrical contact.
Try using a different cable to determine if the issue persists. If only one cable causes static, it’s likely the internal wiring has been compromised.
2. Poor Connection at the Ear Cup Input
The mechanism that connects the cable to the left ear cup of the M50x includes a locking stereo mini-plug. If this doesn’t sit perfectly, you can experience intermittent sound issues—including crackling.
Check to ensure the cable is fully inserted and rotates into a locked position. Sometimes, what seems like full insertion still lacks proper connectivity inside the jack housing, leading to distortion or dropouts.
3. Audio Source Problems
Another overlooked factor is the device you’re plugging the ATH-M50x into. Static can stem from the source device itself due to:
- Inadequate grounding in laptops or desktops, especially when plugged into an AC outlet without grounding pins or surge protectors.
- Electrical interference from nearby electronics or USB ports.
- A malfunctioning headphone jack that causes inconsistent contact with audio terminals.
Try the headphones with another device (such as a smartphone or different computer) to determine if the static disappears. If it does, the problem likely lies in the original audio source itself.
4. Damaged Drivers or Ear Cup Components
If the headphones have been dropped, tightly packed, or exposed to high humidity, internal components such as the drivers or solder joints may have suffered damage. This is less common, but still possible—especially after long-term use or poor storage habits.
In such cases, a static noise may only occur when certain sound frequencies are played or become constant regardless of volume levels.
5. Software and Audio Driver Conflicts
For users experiencing static while using their headphones with computers, sound drivers or software settings can be the culprits. Problems include:
- Outdated or corrupted audio drivers.
- Conflicts between the operating system and third-party audio processing software.
- Improper sampling rates or bit depth settings in your device’s audio configuration.
Update your sound driver, disable enhancements such as DTS or Dolby effects temporarily, and ensure your system’s sample rate settings are consistent with your audio source (e.g., 44.1kHz or 48kHz).
Effective Fixes for ATH-M50x Crackles and Static
1. Clean the Connectors
Use a soft microfiber cloth or a cotton swab lightly dampened with isopropyl alcohol to clean the headphone plug and jack. Make sure everything is dry before reconnecting. This removes any dust, oxidation, or buildup responsible for poor contacts.
2. Replace Faulty Cables
If sound issues occur with only one of the included cables, or if wiggling the cable near the connector causes crackling, it’s time for a replacement. Audio-Technica sells official cable replacements, and there are also high-quality third-party options with gold-plated connectors for added durability.
3. Use a Dedicated DAC or Audio Interface
Low-quality built-in sound cards in laptops or desktops can introduce noise. A small USB-powered DAC (Digital-to-Analog Converter) or an external audio interface with proper shielding and grounding can deliver cleaner audio output to your ATH-M50x.
These devices range from budget options like the FiiO K3 to professional setups like the Focusrite Scarlett series.
4. Reseat or Adjust the Cable at the Headphone End
Remove the cable from the left ear cup and reinsert it, ensuring the plug locks in place. Slight turns or a tighter push into position can resolve poor internal contact. If the jack inside the ear cup is loose or damaged, professional repair may be required.
5. Inspect the Environment for Interference
If you’re using your headphones around strong electromagnetic sources—such as unshielded power adapters, routers, or even fluorescent lighting—they may cause signal interference audible as buzzing or static. Isolate your audio setup and test it in different physical spaces.
When to Consider Professional Repair or Replacement
If you’ve tried different cables, audio sources, and environmental changes and the problem persists, the issue may lie within the internal components of the headphones. Signs that point toward a deeper issue include:
- Consistent static across all devices and cables.
- Visible damage to ear cups or ports.
- Strange behavior during certain frequencies or volume levels.
Contacting Audio-Technica support is recommended. The company offers repair services and, in some cases, may still accept warranty claims depending on the age and condition of your device.
Final Thoughts
The ATH-M50x remains a high-caliber choice for professionals and enthusiasts, but it’s important to keep them in top operational condition. Static and crackling noises can be frustrating and often diminish the performance the headphones are known for. Fortunately, in most cases, the fixes are straightforward—from replacing cables to adjusting your setup environment or upgrading your audio source. By systematically investigating potential causes and following the troubleshooting steps above, you can likely restore your M50x headphones to their crystal-clear audio performance.
Proper care, storage, and periodic maintenance will not only help avoid static problems now but extend the life of your headphones for years to come.
