Speaker Design

The TREBLAB FX100 is 7 inches long, 2.75 inches in height, and weighs in at 1.25 pounds. The compact design makes it an ideal size to attach to your backpack and enjoy music on the go. Speaking of which, TREBLAB includes a carabiner clip with the speaker. The carabiner attaches to an anchor point located on the rear of the speaker, so it’s ready to go straight out of the box. The FX100 also comes with an IPX4 rating which means it can withstand light rain and splashes of water. 

Overall, the TREBLAB FX100 offers an appealing design aesthetic. The speaker features a dark gray metal chassis, surrounded by a black rubber sleeve. A smart design that not only makes for an attractive-looking speaker but also aids in shock absorption. TREBLAB has gone with red accents for the FX100, which you’ll find on either end of the speaker. Finally, touches of silver bring together the rugged-yet-stylish design of the TREBLAB FX100 Bluetooth Speaker.

Taking a closer look at what makes this speaker able to withstand the elements, the body of the TREBLAB FX100 is built with a combination of metal, ultra-durable ABS, and thermoplastic rubber. This allows the FX100 to be tough and durable, but still lightweight and easy to grip. In order to offer protection against dust and moisture, the connection ports are neatly hidden beneath rubber housings.

Speaker Controls & Connectors

On the right of the speaker, you’ll find the control panel offering 5 multi-functional buttons. These include: Power On/Off; Play/Pause; Volume Up/Down; Track Next/Previous; and Call Answer/End. An LED light located above the control panel flashes red and/or blue to let you know when the FX100 is powered on, connected via Bluetooth, or when music is playing.

Additionally, the TREBLAB FX100 offers features such as bass boost, voice assistant compatibility, and an FM radio. A short press of the Power button will enable Bass Boost mode. Whereas pressing the Power button twice (while the speaker is turned on) will enable the FM Radio. To activate your voice assistant, simply press the Phone button twice.

Located beneath a rubber housing on the front face of the speaker, you’ll find the AUX port. Similarly, the power bank can be found on the left side of the speaker, underneath the red TREBLAB logo. The power bank is a truly useful feature, allowing you to keep your devices charged while hiking or camping. Pressing the DC OUT button located on the power bank panel will activate the Power Bank Mode and display the remaining battery level. We’re also happy to report that the TREBLAB FX100 will continue to play music, even while the power bank is in use!

Sound Quality

In terms of sound quality, the TREBLAB FX100 is on par with other Bluetooth Speakers at this price point. Two 5 Watt drivers deliver left/right stereo separation with a frequency response of 80Hz – 20kHz. A common dilemma of portable Bluetooth speakers is their lack of bass response, and the FX100 is no different. In order to compensate for this, TREBLAB has included a Bass Boost Mode. However, if bass is what you’re after – you may be left disappointed here.

Poor bass performance aside, the TREBLAB FX100 offers forward and clear mids, with a bright treble. Adjusting the EQ settings on your smart device will greatly improve the overall sound quality experience and help eliminate distortion and muddiness. Bass performance is significantly improved with an adjusted EQ as well.

In terms of volume, the TREBLAB FX100 delivers! At 25% volume, the FX100 provides enough volume for adequate background music. At 50% volume, the FX100 will bring the party to the pool. While sound does distort at max volume (as with most speakers), you would rarely/never need to listen at this volume.  Designed to be used outdoors, where sound travels, the TREBLAB FX100 offers more than enough volume.

Technical Specs & Features

Shockproof & Splashproof

The TREBLAB FX100 offers an IPX4 waterproof rating, meaning it is splashproof. The Bluetooth speaker can withstand splashes and some light rain, but shouldn’t be submerged in water. While the FX100 doesn’t come with an official IP rating against dust, the enclosed design of the speaker offers a degree of dust protection too. Furthermore, the shockproof design means it will be able to endure the elements, as well an accidental drops.

Battery Life & Charging

Featuring an impressive 35-hour battery life, the TREBLAB FX100 ensures you’ll have non-stop music wherever you go. As with any wireless speaker, the volume at which you listen to music will impact how long the battery lasts. Listening at a moderate volume level (35%) can get you up to 35 hours of battery life. However, listening at 100% volume will likely only last up to 16 hours. Regardless, this is longer than most day hiking trips anyway.

Although charging the speaker can take up to 10 hours to fully charge, this is due to the FX100 having a 7000mAh large-capacity battery for the power bank. A battery level indicator can be found on the power bank, so you’ll always be able to keep track of how much juice is left. Additionally, you can continue to play music on the TREBLAB FX100, even while it’s charging.

Power Bank

Taking a closer look at the power bank, the TREBLAB FX100 offers a standard USB 2.0 port – compatible with all mobile devices. While using the power bank will drain the battery faster, you’re still able to continue playing music even when the power bank is in use. Enabling Power Bank Mode is easy, simply press the red DC OUT button found within the power bank housing.

AUX Connection

For those who prefer a wired connection, the TREBLAB FX100 includes a 3.5mm AUX cable for you to connect to the speaker with. It’s important to note here that music control, as well as phone call management, is not supported via the speaker’s control panel for AUX connections. This will need to be managed on your smart device instead.

Bass Boost

With a frequency range starting at 80Hz, the TREBLAB FX100 lacks in the low-end bass frequency. To compensate for this, the speaker is equipped with a Bass Boost function. Simply short press the Power button to enable it. I would suggest adjusting the EQ on your smart device as well, in order to find your preferred sweet spot. Using the boost by itself can sometimes result in a muddy and distorted sound.

FM Radio

Video might have killed the radio star, but the TREBLAB XR100 certainly keeps radio alive with its FM Radio feature. To access this feature, simply press the Power button twice (ensuring that the speaker is turned on first). While FM Mode can be enabled by using either an AUX cable or Bluetooth, you will need to use the included 3.5mm AUX cable in order to receive a decent signal. Press the Play/Pause button to scan for available channels. Once scanned, you can select either the Volume + or Volume – button to change the selected FM channel.

Wireless Connectivity & True Wireless Stereo (TWS)

The TREBLAB FX100 offers Bluetooth 5.0 + EDR. Bluetooth 5.0 offers a faster and more stable connection compared to previous Bluetooth versions. EDR stands for Enhanced Data Rate. Similar to Bluetooth 5.0, EDR allows for faster speeds and an improvement in battery life as well. Enabling TWS Mode lets you pair two TREBLAB FX100 speakers together and enjoy a True Wireless Stereo sound.

Phone Calls & Voice Assistant

With an integrated microphone included in the TREBLAB FX100 speaker, you can take calls and activate the voice assistant on your smart device. The cVc 6.0 microphone technology is designed to filter out background noise and offer clear voice capture. This is a convenient feature if you’re swimming or in a situation where you can’t immediately access your phone.


TREBLAB offers a range of different portable Bluetooth speakers to suit your needs. The FX100 is similar in size to the TREBLAB HD77, so you might be wondering how it compares. In short, the TREBLAB FX100 offers a longer battery life, as well as a power bank, making it better suited for outdoor use. It’s also slightly cheaper.

How to Pair your TREBLAB FX100 Bluetooth Speaker

Step 1: Ensure that the AUX cable is not plugged in and that the speaker is fully charged.

Step 2: Press and hold the power button for 3 seconds to turn the speaker on. You should hear a “Power ON” voice prompt, followed by “Bluetooth Mode”. The LED will flash red and blue to indicate that the speaker is ready to pair.

Step 3: Scan for Bluetooth devices on your smart device and select TREBLAB FX100.

Step 4: When asked to confirm pairing on your smart device, select “pair”.

Step 5: If a password is required, enter “0000”.

Step 6: Upon successful pairing, you will hear a “Connected” voice prompt. The LED will stop flashing and glow blue.

If you experience any issues with pairing, ensure that the speaker is within 3ft of your smart device and that it is not paired with any other devices. The FX100 can save up to 2 paired devices in memory, but will automatically try to connect to the last paired device first. Power off the speaker, unpair/remove the FX100 from the pairing list on your device and try again. If the problem still persists, try resetting the speaker to factory settings. To do this, press and hold the Volume + and Volume – buttons together for 5 seconds.

How to Enable TWS (True Wireless Stereo) Pairing

Step 1:Place the two FX100 speakers within 3 feet of each other.

Step 2: Power on both FX100 speakers.

Step 3: On the speaker that you want to be the master, press the Phone button twice. You will then hear a voice prompt that indicates which speaker is the left channel and which is the right.

Step 4: Scan for Bluetooth devices on your smart device and select the master speaker.

If the speakers automatically connect to a previously paired device (instead of one another), press and hold the Play/Pause button for 2 seconds on both speakers. When you hear a “Disconnected” voice prompt, the speakers are ready to be paired with one another.

While in TWS mode, you can manage volume levels and other functions via the control panel of either speaker. To disable TWS mode, simply turn off one of the speakers. Enabling the FM Mode or Line-in modes will also disable TWS Mode.
