Setup
1. Charging the Speaker
Before first use, fully charge the speaker. Connect the provided Type-C charging cable to the speaker's charging port and the other end to a compatible USB power source. The speaker takes approximately 1.5 hours to fully charge and provides up to 8 hours of playtime.
2. Bluetooth Pairing
- Ensure the speaker is powered off.
- Press and hold the power button on the speaker until you hear an audible prompt indicating "Bluetooth mode" and the LED indicator begins to flash, signifying it is in pairing mode.
- On your device (smartphone, tablet, laptop), navigate to the Bluetooth settings.
- Select "MiLi Mag-SoundMate" from the list of available devices.
- Once connected, you will hear a confirmation tone, and the LED indicator will stop flashing.
3. True Wireless Stereo (TWS) Pairing
For an enhanced stereo sound experience, two MiLi Mag-SoundMate speakers can be paired together.
- Ensure both speakers are powered off and not connected to any device.
- Power on both speakers. They will automatically attempt to pair with each other.
- Once successfully paired, one speaker will act as the master and the other as the slave. The master speaker will then be ready for Bluetooth pairing with your device.
- Follow step 3 of "Bluetooth Pairing" to connect the master speaker to your device.

4. Mounting the Speaker
The speaker features strong built-in magnets for direct attachment to metal surfaces. For non-metal surfaces, use the included metal rings.
- Direct Magnetic Attachment: Simply place the speaker on any metal surface (e.g., refrigerator, metal cabinet).
- Using Metal Rings: For non-metal surfaces or MagSafe compatibility with non-iPhone 12/13/14 models, attach one of the provided metal rings to the desired surface or the back of your phone/phone case. Ensure the surface is clean and dry before applying the adhesive ring. Once the ring is securely attached, the speaker can be magnetically mounted to it.
- Note: When using with a phone, attach the metal ring to the back of your phone, not directly to the speaker. The speaker can also function as a phone stand when attached to a cell phone.
