TREBLAB X4 Wireless Earbuds Review: 253 Hours of Battery and Earhooks That Never Budge

Tired of earbuds that slip out mid-workout? The TREBLAB X4 wireless earbuds promise to solve that problem with flexible earhooks and a feature set that punches above its price.

The TREBLAB X4 are Bluetooth 5.4 earbuds with earhooks designed for runners, gym-goers, and anyone who needs their earbuds to stay locked in during intense activity. They pack 10mm dynamic drivers, dual ENC microphones, and IPX5 water resistance into a lightweight 8.3g package.

I tested the TREBLAB X4 earbuds through workouts, calls in noisy environments, and daily commutes. At $49.99 (down from $69.99), these wireless earbuds aim to deliver a great experience without the premium price tag.

In this review for TREBLAB X4, I cover the details that matter — battery, fit, sound, and call quality. The short answer? They deliver where it matters most for fitness use, but there are trade-offs worth knowing about before you buy.

What I Liked

The TREBLAB X4 earbuds impressed me in several areas during testing. Here are the standout features that make these wireless earbuds worth considering.

Rock Solid Fit With Earhooks

The flexible earhooks on the X4 earbuds lock these in place securely. I did head shakes, jumped, and ran — they never budged. At just 8.3g per earbud, you barely notice them after a few minutes.

Six eartip sizes are included, so finding a comfortable seal is straightforward. The silky-soft material on the hooks avoids the rigid plastic feel that cheaper sport earbuds often have.

253-Hour Battery Life With Powerbank

Battery life is where the TREBLAB X4 wireless earbuds stand apart from the competition. You get 11 hours of continuous playback per charge, and the 2500mAh USB-C charging case provides an additional 242 hours — totaling 253 hours.

The case also doubles as a powerbank for your phone or other devices. That massive battery is a genuine differentiator you do not see in most earbuds at this price. If you create fitness content and need long battery life from your audio gear, the BOYA BOYAMIC 2 Wireless Microphone offers a similar charging case design with 9 hours of wireless recording per charge.

Clear Call Quality With Dual ENC Mics

The dual unidirectional ENC microphones deliver noticeably clearer calls than I expected. I tested these in the gym and on busy streets, and the Environmental Noise Cancellation isolated my voice from background noise.

For anyone who takes frequent calls during workouts or commutes, the mic quality on the X4 wireless earbuds is a strong selling point.

IPX5 Water Resistance

The TREBLAB X4 earbuds carry an IPX5 rating, meaning they handle sweat and light rain without issue. I wore them through multiple intense workouts and runs in light drizzle — no problems.

This is not full submersion-proof, but for exercise and outdoor use, IPX5 is more than sufficient.

Physical Button Controls

The X4 earbuds use tactile physical buttons instead of touch controls. You can adjust volume, skip tracks, take calls, and activate Siri or Google Assistant with deliberate presses.

This is a smart design choice for workout earbuds with earhooks. Touch controls often register accidental inputs from sweat or adjustments — physical buttons eliminate that frustration entirely. They also work with gloves, which touch panels do not.

What Needs Improvement

No product is perfect, and the TREBLAB X4 earbuds have a few areas worth noting before you buy.

No Active Noise Cancellation

The X4 wireless earbuds rely on passive isolation from the eartip seal and ENC for calls only. If you are shopping for noise cancelling earbuds, Bluetooth ANC models like the Soundcore Space A40 are a better fit — the X4 wireless noise reduction is purely passive. For gym use, this is rarely an issue — gym music and treadmill noise get blocked well enough by the physical seal. For commuting or office use where you want wireless noise cancelling, you will need to look at alternatives like the Anker Soundcore Space A40.

Bulky Charging Case

The charging case is large compared to typical earbuds cases. That 2500mAh battery that gives you 253 hours and powerbank functionality comes at the cost of pocket-friendliness. It fits in a gym bag without issue, but it is noticeably larger than a standard case.

Sound Lacks Audiophile Refinement

Sound quality is good for the price but will not satisfy audiophiles. ZDNET noted that the earbuds are “more than serviceable” at under $50, which matches my experience. The 10mm drivers deliver clear vocals and punchy bass across the 20Hz–20kHz range, but the mids lack the refinement you would get from earbuds costing twice as much.

No Companion App

There is no companion app for EQ customization or firmware updates. What you hear out of the box is what you get. For a product in this price range, that is a common trade-off, but worth knowing if you prefer to tune your sound profile.

How It Compares

The budget workout earbuds market is competitive. Here is how the TREBLAB X4 stacks up against the alternatives.

TREBLAB X3 Pro vs X4

If you have read any TREBLAB X3 Pro review, you know the X3 Pro is a nice pair of sport earbuds with earhooks. The X4 improves on it with Bluetooth 5.4 (up from 5.0), longer battery life, and the powerbank charging case. If you are considering the X3 Pro, the X4 is the clear upgrade at a similar price point.

vs Anker Soundcore Space A40

The Soundcore Space A40 offers ANC, app-based EQ, and multipoint connectivity — features the TREBLAB X4 lacks. However, the Space A40 does not have earhooks, making it less secure for high-impact workouts. The X4 also wins on battery life with 253 hours total versus around 50 hours for the Soundcore. Choose the Space A40 if ANC matters more than fit security.

vs Earfun Air Pro 4

At $90, the Earfun Air Pro 4 delivers ANC and better audio quality with aptX adaptive codec support. One Reddit user noted they “prefer these cheap earbuds over my Bose and Sonys” when comparing Earfun and TREBLAB products. The X4 costs nearly half the price and offers the earhook design for sport use. If your budget allows $90 and you want ANC, the Earfun is strong. If you want dedicated workout earbuds under $50 with exceptional battery, the X4 is the better value.

TREBLAB X Open is another option worth noting — an open-ear design for TREBLAB X4 buyers who want situational awareness during outdoor runs. For runners and gym-goers who prioritize a secure fit and extreme battery life, the TREBLAB X4 earbuds offer something the competitors do not match at this price. If you want that same earhook security with active noise cancellation added, the JLab Epic Air Sport ANC Gen 2 combines ANC and IP66 durability at $99. If you prefer full noise cancellation for commuting and studying rather than earbuds for the gym, the JLab JBuds Lux ANC delivers 70 hours of battery and solid ANC at $60.

Final Verdict

The TREBLAB X4 wireless earbuds deliver exactly what they promise — a secure, durable, long-lasting pair of workout earbuds at a price that is hard to argue with. The earhook design, 253-hour battery, and clear call quality make these stand out in the crowded budget earbuds market.

I am giving the TREBLAB X4 a 4.5 out of 5.

The lack of ANC and a bulky case hold it back from a perfect score. But for the intended audience — fitness enthusiasts, runners, and anyone who needs reliable Bluetooth earbuds for active use — those are minor trade-offs. Customer reviews confirm the positive experience. After reading a review on ZDNET, I replaced my previous top budget pick with these — their verdict that the X4 earbuds “have no business sounding this good for the price” aligns with my own findings.

Bottom line: If you need workout headphones that stay put and keep going for days on a single case charge, the TREBLAB X4 earbuds are an excellent choice at under $50.
