How do I pair this mini speaker with my smartphone?

Pairing is incredibly simple; just search for the Bluetooth name "MT" on your device. First, press and hold the bottom button for 3 seconds until you hear a voice prompt and see the blue LED flashing. Then, open your phone's Bluetooth settings, select "MT", and the blue light will stay solid once connected.

Is this 3W speaker loud enough for outdoor use?

This 3W speaker is perfect for personal listening spaces like a picnic blanket, a hotel room, or an office desk. While it provides a significant volume boost over your phone's built-in speakers, its micro size is not designed to project sound across large, noisy outdoor parties.

Can I test the sound quality before buying in Hong Kong?

Absolutely! Sun Cheong Computer Co. Ltd. encourages customers to test audio products before purchasing. You can visit our Sham Shui Po physical store, pair your own smartphone to our display model, and listen to your favorite tracks to ensure the sound quality meets your expectations.

Why is my speaker making a "DI DI" beeping sound?

The "DI DI" sound is the built-in low battery warning tone. When you hear this sound and notice the music volume decreasing, it means the 200mAh battery is almost depleted. Simply plug it into a 5V USB power source using the Micro USB cable for about 1 hour to fully recharge it.

Can I answer phone calls while listening to music?

Yes, you can answer incoming calls completely hands-free. When a call comes in, the music will pause; simply press the button on the bottom of the speaker once to answer the call, and press it again to hang up and resume your music.

Whether you are listening to podcasts in your hotel room, watching videos at your office desk, or enjoying music on a picnic, this 31.7g micro speaker provides a massive audio upgrade over your standard smartphone speakers without weighing down your bag.

Seamless Bluetooth 5.0 Connectivity

Pairing is instant and stable thanks to the advanced Bluetooth V5.0 chip. The speaker connects effortlessly to your smartphone, tablet, or laptop, ensuring a skip-free wireless audio experience. When you turn the device on, a voice prompt will guide you, and the blue LED indicator will flash until it successfully pairs with your device under the connection name "MT".

Built-in Hands-Free Calling

You can answer phone calls directly through the speaker with a single button press. The multi-function button located on the bottom of the device not only controls power but also acts as a convenient call-answering tool. If your phone rings while you are listening to music, simply press the button once to pick up the call hands-free, making it perfect for conference calls or busy multitasking.

💡 Pro Tip from Our Technicians

"Because this mini speaker is so compact, it utilizes a highly efficient 3.7V 200mAh lithium battery. To maximize the battery's lifespan, always charge it using a standard 5V/1A USB power terminal via the included Micro USB cable—avoid using high-voltage fast chargers! You will know it is time to recharge when the music volume drops and you hear a 'DI DI' warning tone. If you are having trouble finding the pairing name 'MT' on your phone, bring it down to our Sham Shui Po store! Our team at Sun Cheong Computer Co. Ltd. will gladly help you test and pair your new audio gear on the spot."
