Setup
Charging the MW01:
- Locate the USB-C charging port on the MW01.
- Connect the provided USB-C charging cable to the MW01 and the other end to a USB power source (e.g., computer USB port, wall adapter).
- The LED indicator will show charging status. A full charge provides up to 22 hours of battery life. A 15-minute charge can provide up to 50% battery.
Powering On/Off:
- To Power On: Slide the outer casing of the MW01 open to reveal the audio jacks. The device will automatically power on and enter pairing mode. A small white LED on the side will light up.
- To Power Off: Close the outer casing to retract the audio jacks. The device will power off automatically. If no input signal is detected while open, it may also power off after a period of inactivity.
Pairing and Connectivity
Pairing with Wireless Headphones/Earphones:
- Ensure the MW01 is charged and powered on by sliding the casing open. It will automatically enter pairing mode (indicated by a flashing LED).
- Put your wireless headphones or earphones into their Bluetooth pairing mode. Refer to your headphone's manual for specific instructions.
- Place the MW01 close to your headphones. They should automatically connect. Your headphones may announce "paired" or similar.
- Once paired, a small white LED at the other end of the MW01 case will light up, indicating a successful connection.
- The MW01 remembers previously paired devices, so re-pairing is not required for subsequent uses.
Connecting to Audio Sources:
- Single 3.5mm Input (Aux): Gently pull up one of the 3.5mm audio jacks from the MW01. Insert this single jack into the 3.5mm audio output port of your analog device (e.g., exercise equipment, portable game console, older audio player).
- Dual 3.5mm Input (Aircraft): Gently pull up both 3.5mm audio jacks from the MW01. Insert both jacks into the dual audio ports typically found on in-flight entertainment systems.
- After connecting to the audio source, slide the outer case closed to secure the jacks and begin transmitting audio.
Operating Instructions
Shared Listening (Connecting Two Pairs of Headphones):
- First, pair the MW01 with your primary pair of wireless headphones as described above.
- To connect a second pair, slide the outer casing of the MW01 open again, leaving it open for several seconds. This will put the MW01 back into pairing mode.
- Put your second pair of wireless headphones into their Bluetooth pairing mode.
- The MW01 will automatically connect to the second pair. Both pairs of headphones will now receive audio from the connected analog source.
Using with Various Devices:
- In-Flight Entertainment: Use the dual 3.5mm input configuration to connect to airplane seat audio systems. Enjoy movies and music with your personal wireless headphones.
- Exercise Equipment: Connect to treadmills, ellipticals, or other gym equipment with a 3.5mm audio jack to listen to their built-in entertainment or audio programs wirelessly.
- Portable Game Consoles: Enhance your gaming experience by connecting your wireless headphones to consoles that only offer a 3.5mm audio output.
- Analog Audio Devices: Revitalize older stereos, CD players, or record players by enabling them to stream audio to your Bluetooth headphones or speakers.
Maintenance
- Cleaning: Use a soft, dry, lint-free cloth to clean the MW01. Avoid using abrasive cleaners, solvents, or spray cleaners.
- Storage: When not in use, retract the audio jacks into the casing to protect them. Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, avoid fully discharging the device frequently. Charge it regularly, even if not in constant use.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| MW01 does not power on. | Battery is depleted. | Charge the MW01 using the provided USB-C cable. |
