Infrared Wireless Headphones Cutting Out? How to Fix Line of Sight Issues
You’re enjoying your favorite tunes on your brand new infrared wireless headphones when suddenly the audio starts cutting in and out or drops completely. Few things are more frustrating than unreliable wireless audio. If you’re experiencing dropouts, stuttering, or lost connections with your IR headphones, line of sight issues could be the culprit. In this guide, we’ll walk through how to diagnose and resolve the most common line of sight problems to get you back to uninterrupted listening.
Common Infrared Wireless Headphone Line of Sight Symptoms
Infrared wireless headphones rely on a clear line of sight between the transmitter and receiver to maintain a steady connection. Anything that blocks this invisible connection can cause a variety of audio problems:
- Sound cuts in and out intermittently
- Audio stutters or skips
- Sound drops out completely
- Only one side/channel of headphones works
- Headphones won’t connect to transmitter
If you’re experiencing any of the above symptoms, try the following step-by-step solutions to restore a clean line of sight and solid audio connection.
Step-by-Step Infrared Line of Sight Solutions
1. Check for Objects Blocking Line of Sight
First, make sure there are no physical objects between the wireless transmitter and your headphones. Infrared requires a direct line of sight, so things like furniture, walls, plants, or people can easily block the signal. Make sure you have clear air space in a straight line from the transmitter to your headphones.
2. Reposition the Wireless Transmitter
If objects aren’t the issue, try moving the transmitter itself. Place it higher up, like on a bookshelf, to reduce potential obstructions. Also make sure it’s facing the direction where you typically use your headphones. Avoid placing the transmitter inside cabinets or behind other electronics that could interfere with the infrared signal.
3. Reduce the Distance to the Transmitter
Infrared has a limited range, usually up to 30 feet (10 meters) at most. The further you are from the transmitter, the weaker and less reliable the signal. Try moving closer to see if dropouts disappear. Experiment to find the max distance you can be before sound cuts out.
4. Clean the Transmitter and Headphone IR Ports
Dust, dirt, and oils can accumulate over time on the small infrared ports of your transmitter and headphones, partially blocking the light transmission. Carefully clean the IR windows on both with a soft, slightly damp cloth. A clean connection improves IR signal strength and reliability.
5. Replace or Recharge Headphone Batteries
Weak batteries can cause intermittent sound and disconnections even if line of sight is clear. Make sure your batteries have a full charge. If problems persist, try fresh replacement batteries. Older NiMH batteries can suffer from “memory effect” where they no longer hold a full charge, so upgrading to newer higher-capacity NiMH rechargeables can help.
6. Re-pair or Reset Your Headphones
If line of sight issues have been ruled out, your headphones may need to be re-paired with the transmitter. Turn off both devices and turn them back on to re-initiate pairing. If that doesn’t work, consult your manual for model-specific instructions on resetting your headphones to factory defaults and re-pairing from scratch.
Preventing Future Line of Sight Problems
Now that you’ve got your infrared wireless headphones working reliably again, keep these best practices in mind to prevent future line of sight issues:
- Always aim for clear line of sight between transmitter and headphones
- Position the transmitter in a raised, unobstructed spot facing your listening area
- Keep the transmitter away from other electronics that could interfere
- Stay within the recommended range of your specific headphones (usually 20-30 feet max)
- Occasionally clean IR ports to remove dust/debris
- Use fresh batteries and replace them regularly
Infrared Wireless Headphones Troubleshooting Checklist
Still having issues with your infrared wireless headphones cutting out? Step through this checklist to narrow down the culprit:
- Are there any objects blocking the line of sight between your transmitter and headphones?
- Is the wireless transmitter positioned up high and facing your listening area?
- Are you within 20-30 feet of the transmitter?
- Are the IR ports on the transmitter and headphones clean and unobstructed?
- Do your headphone batteries have a full charge? Have you tried fresh batteries?
- Have you tried re-pairing or resetting your headphones and transmitter?
If you’ve gone through all the above steps and your infrared wireless headphones are still cutting out, there may be an underlying hardware issue. Contact the manufacturer’s support or take them in for repair.
Infrared remains a popular wireless technology for its affordability and low power usage. But its reliance on direct line of sight means you may occasionally run into audio dropouts. By understanding how IR works and following these troubleshooting steps, you can quickly diagnose and resolve line of sight issues to get back to enjoying your wireless headphones.
