If your Noble Audio wireless IEM case won't charge, follow this diagnosis to identify the cause and get it working again—including when to buy a replacement.

Quick answer

Start with the cable and charging port, then check the case battery and earbud contacts. If the case still won't charge and it's a FoKus Amadeus, a replacement case is your fix.

Why your charging case might stop working

Charging cases for wireless IEMs are small electronic devices with their own battery and charging circuitry. Over time, the USB port can collect dust, the internal battery can degrade, or the connection pins that charge the earbuds can get dirty. These are the most common failure points, and each has a simple fix or a clear replacement signal.

When a replacement case is the right call

If you own a Noble Audio FoKus Amadeus and the case won't charge after trying different cables and cleaning the port, the internal charging circuit may have failed. Noble offers a dedicated replacement case for the FoKus Amadeus. It comes as a case only—no earbuds or accessories—so it's a straightforward swap if your original case is lost or broken. This is a simpler and more affordable option than buying a whole new IEM set.

Diagnosis: Why won't your IEM case charge?

1. Check the cable and power source: Use a different USB cable and a different charger (wall adapter or computer port). The cable is the most common failure point. If the case charges with another cable, the original cable is the problem. If a different cable works, stop here and replace the cable.
2. Inspect and clean the charging port: Look inside the case's USB port for dust, lint, or debris. Use a wooden toothpick or compressed air to gently clean it. A blocked port prevents the charging circuit from making contact. If cleaning the port fixes the issue, stop here.
3. Test the earbud contact pins: Dirt or oxidation on the case's charging pins (where the earbuds sit) can prevent the case from detecting the earbuds and initiating charge. Wipe the pins and earbud contacts with a dry cloth or isopropyl alcohol on a cotton swab. If the case now charges the earbuds, stop here.
4. Reset the case battery: Some cases have a pinhole reset button. If yours does, press it with a paperclip for 5 seconds. If not, leave the case plugged in for 30 minutes even if no lights appear—a deeply discharged battery can take time to wake up. If the case still shows no charging light after 30 minutes, the internal battery or circuit is likely dead.
5. Replace the case: If you've tried steps 1–4 and the case still won't charge, the internal charging circuit has failed. For the Noble Audio FoKus Amadeus, order the official replacement case. It's a case-only part, so transfer your earbuds and cable to the new case.
