If you want marathon battery life with a charging case that doubles as a power bank, choose TREBLAB X3-Pro; if you need a featherweight, everyday earbud with a newer Bluetooth version and a real button you can press without looking, choose Monster Clarity 102. Both are true wireless earbuds with four ENC microphones aimed at clear calls, so the real decision comes down to fit, battery strategy, and how you control them.
• TREBLAB X3-Pro — biggest strength: a claimed 12 hours per charge and up to 192 hours total with the charging case, plus earhook fit and IPX5 sweat resistance.
• TREBLAB X3-Pro — biggest trade-off: the earhook design is bulkier than a plain bud, and IPX5 is a step below the Monster's IPX6 water resistance.
• Monster Clarity 102 — biggest strength: roughly 4 grams per bud, Bluetooth 5.4, and button controls, with 6 hours per charge and 24 more from the case.
• Monster Clarity 102 — biggest trade-off: far shorter total playtime than the TREBLAB, and no earhook to lock the bud in place.
• Buy the TREBLAB X3-Pro if you train hard, sweat a lot, and want the longest possible runtime.
• Buy the Monster Clarity 102 if you want a light, unobtrusive bud for calls, commuting, and all-day wear.
The X3-Pro is built around one idea: staying in your ears and staying powered through long, sweaty sessions. The earhook shape wraps over the ear instead of relying on the ear canal alone, and TREBLAB ships five sizes of silicone tips so you can dial in the seal. The drivers are 14.2mm dynamic units with a 20 Hz–20,000 Hz range, 32 ohm impedance, and 106 dB sensitivity, which is the kind of spec sheet that points to a bass-forward, energetic tuning rather than a flat, studio-neutral one.
Battery is the headline. You get up to 12 hours per charge, and with the 2,600 mAh case you're looking at up to 192 hours of total listening time. The case itself charges over USB-C in about two hours and works as a power bank, so it can top up your phone on a trip. That combination is unusual and genuinely useful if you travel or train away from outlets.
The call side uses four ENC microphones to reduce background noise and lift your voice, and there's a 60 ms gaming-mode latency figure for people who care about audio staying in sync with video. Bluetooth 5.3 with a 33-foot range covers normal room-to-room use, and touch controls handle playback. IPX5 means sweat and light rain are fine, but I wouldn't submerge them.
Who should buy it: runners, gym-goers, and travelers who want maximum runtime and a fit that won't shift mid-workout. Who should skip it: anyone who dislikes earhooks or wants the smallest, most discreet bud possible — the wrap-around design is the point, but it's also the compromise.
The Clarity 102 Plus goes the other direction: make the bud disappear in your ear. Each earbud is about 4 grams, and Monster says that's roughly 15% lighter than typical models in this class. With four pairs of rubber ear caps, the goal is a comfortable in-ear seal you can wear for hours without pressure. It's an in-ear bud shape with no hook, so it sits inside the ear rather than around it.
Sound here is tuned for mid and high frequency clarity, with a digital audio processor and dynamic drivers doing the work. If you mostly listen to podcasts, vocals, and acoustic material, that emphasis makes sense. The four ENC mics (two per earbud) plus an AI algorithm handle calls, which is the same core idea as the TREBLAB but with a different implementation.
Runtime is the clear trade-off: about 6 hours per charge and 24 more from the case, for roughly 30 hours total. That's plenty for a normal day or two, but it's nowhere near the TREBLAB's numbers. Charging is over USB-C. Water resistance is IPX6, which is a notch above IPX5 and handles splashes and heavy sweat with a bit more margin.
Controls are a genuine differentiator. Instead of touch, you get physical press buttons for play/pause, track skipping, volume, calls, and voice assistant. Buttons are unambiguous — no accidental taps when you adjust the bud. Bluetooth 5.4 is the newer spec, which usually means steadier connections and lower power draw, and one-step pairing means they reconnect automatically when you pull them from the case.
Who should buy it: commuters, office and call-heavy users, and anyone who wants a light bud with tactile controls and doesn't need extreme battery. Who should skip it: endurance athletes and travelers who want days of runtime between charges, or people who need an earhook to keep a bud locked in during sprints and burpees.
• Best for battery life → TREBLAB X3-Pro. Up to 12 hours per charge and up to 192 hours total with the case is in a different league.
• Best for all-day comfort → Monster Clarity 102. At roughly 4 grams per bud, it's the lighter, less noticeable option.
• Best for hard workouts → TREBLAB X3-Pro. The earhook and five tip sizes are designed to stay put when you're moving.
• Best for water resistance → Monster Clarity 102. IPX6 edges out IPX5 if you're worried about splashes.
• Best for control feel → Monster Clarity 102. Physical buttons beat touch panels when you're wearing gloves or mid-run.
• Best for newer connectivity → Monster Clarity 102. Bluetooth 5.4 versus 5.3, with one-step pairing after the first setup.
• Best for travel and backup power → TREBLAB X3-Pro. The case doubles as a power bank, which is a real convenience on the road.
• Best for call clarity in noise → a tie on paper. Both use four ENC mics; the difference is implementation, not mic count.
In my opinion, the TREBLAB X3-Pro is the pick if your earbuds live in a gym bag or a carry-on. The runtime, the power-bank case, and the earhook fit solve the two problems that actually ruin workouts — buds falling out and dying mid-session. The Monster Clarity 102 is the better everyday bud if comfort, button controls, and newer Bluetooth matter more than endurance; it's lighter and simpler to live with, you'll just charge it more often. If I had to choose one for mixed use, I'd take the TREBLAB for its flexibility, and the Monster for anyone who wants a near-weightless bud and doesn't mind the shorter battery.
FAQ
how to use wireless headphones mic on pc
how to use mic on wireless headphones
Once the earbuds are paired, the microphones work automatically for calls — you just talk. On the TREBLAB X3-Pro and Monster Clarity 102, the ENC mics pick up your voice and reduce surrounding noise. There's no separate switch to enable; the mic is active whenever a call or voice app is using the earbuds.
can you use bluetooth headphones as a mic
Yes, as long as the earbuds include a microphone and your device supports the hands-free Bluetooth profile. Both of these models have four built-in mics, so they can serve as your mic for calls and voice chat. Audio quality as a mic won't match a dedicated desktop microphone, but it's fine for meetings and phone calls.
do all bluetooth headphones have a microphone
No. Some Bluetooth headphones are designed for listening only and have no mic at all. Others, like the TREBLAB X3-Pro and Monster Clarity 102, include multiple ENC microphones specifically for calls. If clear voice pickup matters to you, check the spec sheet for a stated mic count before buying.
