The Bottom Line:​

Premium quality, at a budget-friendly price tag, the TREBLAB X3 Pro could easily be your next favorite workout earphones! Packed inside a compact travel case that offers 9 hours of playtime plus 4 extra charges, the X3 Pro provides excellent sound quality and clarity. The TREBLAB X3 Pro also boasts an IPX7 waterproof rating, so when you’ve finished your sweat-induced workout at the gym, you can take the music with you into the shower!

If you missed our previous review and haven’t heard of TREBLAB before, they manufacture high-quality wireless audio products at an affordable price. It may sound too good to be true, but TREBLAB is currently dominating the budget tier, while still competing with premium brands like Bose or Sony in terms of features and build quality.

In our previous review, we looked at the TREBLAB Z3 wireless headphones. If you’re more of an earbud-type person while working out, then these might be just what you’re looking for! With sought-after features such as Bluetooth 5.0, comfortable build quality, an IPX7 waterproof rating, and a built-in mic, there’s so much and more to look forward to!

Unboxing & First Thoughts

First impressions are important and this is where TREBLAB has excelled! Housed within a sturdy box with a magnetic opening, the first sense you’ll gather from the X3 Pro is that of quality. Once opened, you’ll find the earbuds and their housing nestled neatly within a firm foam enclosure. Additional ear tip sizes, along with the USB-C charging cable, are packed neatly in a cardboard box. An in-depth user’s manual booklet, as well as a quick-start guide to pairing your X3 Pro, can be found at the bottom of the package.

Earphone Design & Comfort

TREBLAB has opted for an all-black design. From the case to the earbuds themselves, almost everything is matte black (except for the small TREBLAB logo which has a gloss finish). Personally, I love this design and find it to be stylish, yet sleek. The earbuds are catered towards gym-goers, but will still blend in effortlessly only on your way to work or school.

The X3 Pro Earbuds feature ear hooks to ensure a secure fit, even during vigorous workouts. They are comfortable to wear for extended periods, even for users with glasses. TREBLAB has also included 3 different ear tips, ensuring you’re able to find a fit that best suits your ear size.

Being in-ear headphones, the TREBLAB X3 Pro has no sound leakage at standard volumes. This also makes them ideal for use during your daily commute or for within an office environment. As mentioned already, they also offer good sound isolation and block out a fair amount of external noise.

Earphone Controls

The controls on the TREBLAB X3 Pro are the same on both earbuds. Each earbud has a volume + and volume – button, which also doubles as a next track/ previous track button when long-pressed.The round TREBLAB logo is a multi-function button (MFB), which allows you to pause/play your music (short press), turn the earphone on/off (long press), as well as answer/end/reject calls. Your voice assistant is also activated using the multi-function button.

Due to both earphones having these controls, this allows you to use each earphone independently of the other. If you’d like to still have some awareness of your surroundings and listen to music with just one earphone – you are able to do so. This means you could enjoy non-stop playtime but have one earbud charging while listening to the other.

Sound Quality

We were pleasantly surprised by the sound quality of the TREBLAB X3 Pro Earbuds across all genres of music. Featuring 11mm drivers, the X3 Pro delivers excellent clarity and well-balanced sound. Bass is tight and punchy, the mid-range is clean and free of distortion, and treble performs when it needs to, without being overpowering.

The TREBLAB X3 Pro also offers a wide soundstage and excellent imaging, resulting in an immersive listening experience. It’s hard to believe these headphones are priced below $70 as they compete with more high-end brands in terms of sound quality. These earbuds certainly deserve a spot on a list of the best workout earphones!

Technical Specs & Features

Battery Life & Charging

Looking at battery life, you can expect up to 9 hours of continuous playtime off a single charge. This is certainly longer than any workout will be! Additionally, the case provides an additional 4 charges as well, before needing to be recharged. This means you’ll get around 45 hours in total, depending on the volume at which you listen to your music. Charging your case takes just 2 hours and TREBLAB has included a USB-C charging cable.

One thing that stands out about the TREBLAB X3 Pro earphones is their magnetic connection to the charging case. If you’ve ever had wireless earphones without a magnetic connection, then you’ll know the pain of getting ready to start your workout, only to find that one (or both) of your earbuds didn’t actually charge in their housing, leaving you without music in at least one ears. TREBLAB’s inclusion of a magnetic connection ensures that each earbud will charge when not in use and is a truly useful and much-appreciated feature!

Wireless Connectivity

The TREBLAB X3 Pro Earbuds feature Bluetooth 5.0. This is one of the latest Bluetooth versions available and offers faster speeds and a better range compared to previous versions. The X3 Pro also features a Qualcomm QCC chipset with aptX to ensure high-quality audio.

IPX7 Rating – Fully Waterproof

A requirement of any workout earphone is that it can withstand the inevitable sweat involved and the TREBLAB X3 Pro doesn’t disappoint here either. Offering an IPX7 waterproof rating, the earphones are fully waterproof (and sweatproof). This means they can actually be submerged in water at a depth of 1m (about 40 inches) for 30 minutes – so you could even take them into the shower with you after your workout!

Voice Assistant & Phone Calls

The TREBLAB X3 Pro is compatible with almost all voice assistants, including Siri, Alexa, and Google Assistant. To activate your voice assistant, simply press the multi-functional button on either earphone twice. For managing phone calls, pressing the MFB once will answer a call (and automatically pause your music) while pressing and holding the MFB will reject the call.

How to Pair your TREBLAB X3 Pro Earphones

Step 1: Ensure that the protective stickers on the charging contacts have been removed.

Step 2: Remove the earbuds from the charging case. They will automatically turn on.

Step 3: Scan for Bluetooth devices on your smart device and select TREBLAB X3 Pro_L.

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

Step 5: Upon successful pairing, you will hear the voice prompt say “Connected”.

If you experience any issues with pairing, ensure that the earphones are within 30ft of your device and that they are not paired with any other devices. The X3 Pro Earphones can only be paired with 1 device at a time. If the problem still persists, try resetting the earphones to factory settings. To do this, turn the headphones OFF, then press and hold the Multi-Function Button on both earbuds for 11 seconds. When you see a purple light and hear a voice prompt, place the earphones back into their charging case. Your earphones will now be reset and ready to be used.
