Setup

What's in the Box:

• FiiO EH11 Retro On-Ear Bluetooth Headphones
• Foam earpads (2 pairs)
• USB A to Type-C charging cable (1)
• Quick guide (1)

Charging the Headphones:

Before first use, fully charge the headphones. Connect the provided USB A to Type-C charging cable to the USB-C port on the headphones and a power source. A full charge takes approximately 1.5 hours and provides up to 30 hours of playback time.

Bluetooth Pairing:

1. Ensure the headphones are powered off.
2. Press and hold the power button until the indicator light flashes, indicating pairing mode.
3. On your device (smartphone, laptop, etc.), enable Bluetooth and search for available devices.
4. Select "FiiO EH11" from the list of devices to connect.
5. Once connected, the indicator light will change to a steady color or flash intermittently.

Dual-Device Connection:

The FiiO EH11 supports simultaneous connection to two devices. After pairing with the first device, put the headphones back into pairing mode and connect to the second device. The headphones will automatically switch between devices for music, calls, or other audio, prioritizing active audio streams.

Operating Instructions

Controls:

The EH11 features intuitive physical controls for ease of use:

• Wooden Control Knob: Rotate the wooden knob on the earcup to adjust volume. Press the knob to control track skipping (e.g., single press for play/pause, double press for next track, triple press for previous track).
• Multi-function Button: Use the dedicated button for answering/ending calls.

LDAC High-Resolution Audio:

The EH11 supports LDAC for high-resolution wireless audio. To utilize this feature, ensure your source device also supports LDAC output. LDAC provides approximately three times higher transmission rates than standard SBC/AAC codecs, delivering near-lossless audio quality. Note that using LDAC may result in marginally higher power consumption. This feature is enabled by default but can be deactivated via the FiiO Control App.

Troubleshooting

Common Issues and Solutions:

• No Power: Ensure the headphones are fully charged. Connect the USB-C charging cable and allow it to charge for at least 10 minutes before attempting to power on.
• Cannot Pair: Make sure the headphones are in pairing mode (indicator light flashing). Turn off and on your device's Bluetooth, then try pairing again. Ensure the headphones are not already connected to another device.
• Poor Sound Quality/Disconnections: Check if the headphones are within the effective Bluetooth range of your device. Avoid obstacles that may interfere with the signal. If using LDAC, ensure your device supports it and try switching to a different codec in the FiiO Control App if issues persist.
• Controls Not Responding: Power cycle the headphones (turn off and then on). Ensure the FiiO Control App is updated to the latest version if using app-based controls.
