# I have static or can't hear out of one or both sides of my ILS (Focus) Headphones
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?***](https://support.unyte.com/how-do-i-charge-my-focus-amplifier?hsLang=en)
#### **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?**](https://support.unyte.com/how-do-i-test-my-focus-amplifier?hsLang=en)*
#### **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 ILS (Focus) Headphones**](https://support.unyte.com/how-do-i-test-my-focus-headphones?hsLang=en)*for more information*
- You’ve completed the Left and Right ear test itself
#### **Step 4: Locating the source of the static/no sound🛠️**
1. 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.**
2. 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.**
3. 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.**
