How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of sport-first earbuds that stay hooked in your ears through runs, gym sessions and rainy commutes — and that double as a backup phone charger — choose TREBLAB X4; if you need proper over-ear headphones with long battery life for travel, work and laptop listening, choose Eduiosma Headphones.
• TREBLAB X4 — biggest strength: Ear-hook fit that locks each bud in place, plus a 2500mAh powerbank case that adds 22 full recharges and can top up your phone.
• TREBLAB X4 — biggest trade-off: In-ear, passive-isolation design means no active noise cancelling, and the hook fit isn't for people who dislike things sitting inside their ear canal.
• Eduiosma Headphones — biggest strength: True over-ear comfort with memory foam and faux leather, 80 hours of playtime per charge, and a 3.5mm wired fallback.
• Eduiosma Headphones — biggest trade-off: Over-ear bulk (a carrying case roughly 8 x 7 x 2 inches) and no ear-hook security, so they're not the pick for high-movement workouts.
• Pick TREBLAB X4 if you're a runner, gym-goer or cyclist who wants a secure, sweat-and-rain-resistant fit.
• Pick Eduiosma Headphones if you want immersive over-ear listening at a desk, on a plane or during long work sessions.
The X4 is built around movement. Each bud uses a hook shape that wraps the ear rather than relying on friction alone, and at roughly 0.02 lb per bud the design intent is clearly "set it and forget it." TREBLAB pairs that with IPX5 water resistance, so rain and sweat aren't a dealbreaker. The 10mm dynamic drivers run 20Hz–20kHz at 105dB sensitivity with 32 ohm impedance, which tells you these are tuned to be easy to drive from a phone and punchy enough for training playlists. Bluetooth 5.4 gives you a 10-meter range, and the 60ms low-latency mode is there for mobile gaming.
The battery story is the headline. You get up to 11 hours per charge, and the 2500mAh case holds enough for 22 additional full charges — TREBLAB lists up to 253 hours total playtime, with the case itself rated for 242 hours. The case also works as a powerbank for your phone, which is genuinely useful on long days out. Two microphones with ENC handle calls, filtering street and gym noise, and passive noise isolation is baked into the in-ear seal. You get three buttons per earbud, Google Assistant support, six sizes of silicone tips, a USB-C cable and a cleaning kit in the box.
Who should buy it: runners, lifters, cyclists and anyone who wants one compact kit that covers music, calls and emergency phone charging. Who should skip it: if you want over-ear cups, active noise cancelling, or you simply don't like the feeling of in-ear tips, this isn't your design.
Eduiosma takes the opposite approach — comfort and endurance over portability. These are over-ear headphones with oval earcups in faux leather over memory foam, which is the combination that typically lets you wear headphones for hours without pressure hotspots. The 40mm dynamic drivers are significantly larger than the X4's 10mm units, and with the same 20Hz–20kHz range, 105dB sensitivity and 32 ohm impedance, they're positioned for a fuller, roomier sound — the brand describes it as deep bass and Hi-Fi stereo.
Battery life is rated at up to 80 hours per charge with a 2-hour charge time, which is remarkable for over-ear headphones and means you can travel for a week without thinking about a cable. Bluetooth 6.0 is the newest version in this comparison, and the 33-foot range is longer than the X4's 10 meters on paper. Crucially, Eduiosma adds a 3.5mm jack for wired listening — so if the battery dies or you're on a plane with a seatback screen, you're not stuck. Controls are push-button, with a built-in microphone for calls.
The trade-offs are physical. At 8.8 ounces these are noticeably heavier than a pair of earbuds, the carrying case is roughly 8 x 7 x 2 inches, and there's no water-resistance rating listed, so I wouldn't treat them as gym or rain gear. Sound isolation here is passive, not active cancellation.
Who should buy it: remote workers, students, frequent travelers and laptop users who want long sessions, wired backup and over-ear comfort. Who should skip it: anyone whose priority is a secure fit during sweaty, high-impact activity.
• Best for running and gym work → TREBLAB X4. The ear-hook design and IPX5 rating are made for movement; the Eduiosma's over-ear build is not.
• Best for total battery endurance → Eduiosma Headphones. 80 hours per charge with a 2-hour refill is a simpler, longer single-charge experience.
• Best for all-day, all-week power without a wall outlet → TREBLAB X4. The 2500mAh case delivers up to 253 hours of combined playtime and recharges your phone too.
• Best for comfort over long listening sessions → Eduiosma Headphones. Memory foam and faux leather over-ear cups beat in-ear tips for marathon desk or flight sessions.
• Best for wired fallback → Eduiosma Headphones. The 3.5mm jack means zero downtime; the X4 is wireless-only with no jack.
• Best for calls in noisy places → TREBLAB X4. Dual mics with ENC are explicitly aimed at street noise, wind and gym crowds.
• Best for gaming and video sync → TREBLAB X4. The 60ms low-latency mode is the concrete advantage here.
• Best for travel-light packing → TREBLAB X4. A 2.43 x 1.58 x 3.87-inch case slips into a pocket; the Eduiosma case does not.
In my opinion, the right answer depends entirely on how you'll use them — but if I had to pick one, I'd buy the Eduiosma Headphones for general listening, work and travel, because over-ear comfort, 80-hour battery and a wired backup cover more everyday situations for more people. That said, if your routine revolves around running, lifting or cycling, I'd take the TREBLAB X4 without hesitation — the hook fit, IPX5 rating and powerbank case solve problems the Eduiosma simply wasn't designed for. Buy the X4 for the gym; buy the Eduiosma for the desk.
FAQ
It depends how you count. The Eduiosma gives up to 80 hours on a single 2-hour charge. The X4 gives up to 11 hours per charge, but its 2500mAh case adds 22 more charges for up to 253 hours total — so the X4 wins on total endurance, the Eduiosma on single-charge simplicity.
Yes. Eduiosma includes a 3.5mm jack for wired listening, so you can keep going with a cable. The TREBLAB X4 is wireless-only, with no headphone jack at all.
Both have built-in microphones. For noisy outdoor environments I'd lean TREBLAB X4 because of its dual mics and ENC noise filtering. For long calls at a desk, the Eduiosma's over-ear fit and comfort make more sense to me.
