This article will guide you to resolve the static/no sound in your headphones or determine the source of the issue. It is important to follow the steps in order. The most common reasons headphones produce static/no sound are as follows:
- Low amplifier charge
- Headphone to amplifier/audio to amp connection not fully secure
- Headphone connector and/or internal headphone cable damaged
Step 1: Charge your Amplifier
Plug the amp charging cable into the DC port at the back of the unit. Plug the other end of the cable into a wall outlet. A green light indicates it is charging and turns off once fully charged.
- For detailed instructions refer to How do I charge my Focus Amplifier?
Step 2: Confirm your amplifier is performing as intended: ✅
- The green light on the back of the amp turns on while charging and then off once charging is complete. (Charging can take up to 6 hours)
- The blue light on the front of the amp turns on and remains solid when turning the AC knob past 0.5
If you can check BOTH of the boxes, your amp is performing as intended. If not, proceed to Step 3 of the following article as your amp could be the cause for static in the headphones: How do I test my Focus Amplifier?
Step 3: Confirm the following: ✅
- Your amplifier and audio device are fully charged
- The AC knob on the amp is set to 0.5, BC knob set to 0 and device volume is full
- Confirm your headphone connector cable is fully secured to the four-pin connector on the amplifier labeled ‘Headphones’ and your audio to amp cable is fully secured on both ends
- Refer to Steps 2-4 of How do I test my Focus Headphones for more information
- You’ve completed the Left and Right ear test itself
Step 4: Locating the source of the static/no sound🛠️
- Wiggle and press on various parts of the headphone cable and audio to amp cable.
- If the issue resolves it may indicate the corresponding cable is faulty.
- Tighten and loosen the headphone connector cable while the test is playing
- If the issue resolves it may indicate your connection was too loose, or sometimes too tight.
- Ensure the four pin connector on the headphone cable is not bent, missing or damaged.
- If any of these components are damaged it may cause static or no sound.
