• Hentrixis Earbuds — biggest strength: a conventional in-ear fit with 13mm dynamic drivers, 4-mic ENC call clarity and up to 35 hours of total playtime.
• Hentrixis Earbuds — biggest trade-off: they seal your ear canal, so you get isolation but you lose awareness of what's happening around you.
• PTHTECHUS Open Ear Headphones — biggest strength: an open, above-the-ear design that weighs just 4.8g per bud and stays comfortable with glasses, plus a longer 40-hour total figure.
• PTHTECHUS Open Ear Headphones — biggest trade-off: open-ear means less bass punch and far less isolation in loud places.
• Pick Hentrixis Earbuds if you mainly listen indoors, on transit or in calls and want maximum immersion for your money.
• Pick PTHTECHUS Open Ear Headphones if you run, cycle, drive or work in a busy space and want your ears left open to the world.
The Hentrixis Earbuds are the classic "true wireless" formula done properly. Bluetooth 5.3, a 10-metre range, touch controls and a metal-and-plastic charging case with an LED display that shows the battery percentage instead of four vague blinking dots. That last detail matters more than it sounds — guessing whether you have 60% or 15% left is the single most annoying part of owning cheap earbuds, and here you just look at the case.
Sound is where the hardware does the talking. The 13mm dynamic drivers are on the large side for in-ear buds, and combined with a 20Hz–20kHz frequency range and 32-ohm impedance, that points to a warm, bass-forward tuning. Bigger drivers move more air, so you should expect punchy low end and enough detail up top for podcasts, pop and electronic music. Nothing here promises audiophile neutrality, and I wouldn't expect it.
Calls are the other headline. Four microphones running ENC (Environmental Noise Cancellation) is a genuinely useful setup — two mics per bud typically means one listens to your voice and one samples the background so the algorithm can subtract it. In practice that's the difference between "I can hear you but it's noisy" and a call the other person doesn't complain about.
Battery: up to 35 hours total with the case, around 2 hours to charge, and a Type-C port so you're not hunting for a proprietary cable. No headphone jack, wireless only.
Who should buy it: commuters, students, office workers, anyone who wants immersive sound and reliable calls from a compact case.
Who should skip it: runners and cyclists who need to hear traffic, people who hate the plugged-ear feeling, and anyone who's had ear infections or pressure discomfort from sealed tips. If you wear glasses, in-ear buds are fine — it's the open-ear crowd that really benefits there.
The PTHTECHUS pair takes the opposite approach. Instead of sealing your canal, each bud rests gently above the auricle, hooking over the ear. The result is a fit that's lighter and more breathable than in-ear designs, and the spec sheet backs that up: 4.8 grams per earbud. For comparison, the whole package including the case weighs 44 grams, so the buds themselves are almost nothing on your head.
That design exists for one reason — awareness. You hear your music and your surroundings at the same time. On a bike, on a run, in an open-plan office or while driving, that's not a compromise, it's the point. PTHTECHUS also calls out compatibility with glasses, which is a real pain point for in-ear and over-ear users alike.
Battery is the strongest number in this comparison. Up to 8 hours per charge, around 40 hours total with the case, a 300mAh case battery, and a 1.5-hour charge time for the buds. There's also a quick-charge claim: roughly 15 minutes gets you about 3 extra hours. That's the kind of thing that saves you on the way out the door.
Connectivity is Bluetooth 5.4 — one generation newer than the Hentrixis — with 10 metres of range, ultra-low latency and auto-pairing when you open the case. Lower latency matters if you game or watch video, since audio and picture stay in sync. Calls use ENC as well, and PTHTECHUS specifically mentions clear calls in windy conditions, which is a sensible claim for an open design where wind hits the mic directly. Directional sound tech is there to limit leakage so people around you aren't hearing your podcast.
Two things to be honest about. First, the driver spec is thinner here — dynamic drivers, 117dB sensitivity, 20Hz–20kHz — with no driver size given, and no impedance figure. Open-ear headphones physically can't trap bass the way a sealed tip does, so expect a lighter low end. Second, noise control is listed as adaptive cancellation, but on an open design that's about call clarity, not blocking out a plane cabin. Don't expect silence.
Who should buy it: runners, cyclists, gym-goers, drivers, delivery workers, glasses wearers and anyone doing all-day wear who wants their ears to stay cool and unblocked.
Who should skip it: anyone who wants to disappear into an album on a noisy train, and bass-first listeners.
• Best for battery life → PTHTECHUS Open Ear Headphones (up to 40 hours total versus 35 hours on the Hentrixis).
• Best for sound isolation and bass → Hentrixis Earbuds (sealed in-ear fit, 13mm dynamic drivers, 32-ohm impedance).
• Best for situational awareness → PTHTECHUS Open Ear Headphones (open design, nothing blocks your ear canal).
• Best for glasses wearers and all-day comfort → PTHTECHUS Open Ear Headphones (4.8g per bud, sits above the auricle).
• Best for newer Bluetooth → PTHTECHUS Open Ear Headphones (5.4 versus 5.3), which also helps with low-latency video and gaming.
• Best for knowing your exact battery level → Hentrixis Earbuds (LED percentage display on the case).
• Best for the smallest, most pocketable carry → Hentrixis Earbuds (compact case, metal-and-plastic shell, Type-C charging).
• Best for commuting and calls in noisy places → Hentrixis Earbuds (4-mic ENC plus the natural isolation of a sealed fit).
• Best for running, cycling, driving and shared workspaces → PTHTECHUS Open Ear Headphones.
One more thing worth weighing: PTHTECHUS states a warranty of one month for returns and exchanges via logistics, a three-month exchange for quality issues, and a one-year repair warranty for product faults. Hentrixis doesn't state a warranty term on its sheet. If after-sales support matters to you, that's a point in PTHTECHUS's column.
Neither sheet lists a price, so don't take my word for value — check the current price on Amazon for both before you commit, because these two sit in different categories and the gap can swing either way.
In my opinion, the PTHTECHUS Open Ear Headphones are the more interesting buy for most people, and the one I'd pick. The 4.8g open-ear fit, Bluetooth 5.4, 40-hour total battery and the stated one-year repair warranty solve problems that actually show up in daily use — comfort, awareness and charging anxiety. I'd only steer you to the Hentrixis Earbuds if your priority is immersive, bass-heavy sound with strong call isolation in noisy places, where a sealed in-ear design simply wins. Both are sensible; they're just built for two different lives.
FAQ
PTHTECHUS, clearly. The open design rests above your ear rather than inside it, weighs 4.8g per bud, and lets you hear traffic and surroundings. The Hentrixis seal is the opposite of what you want on a road run.
On paper, yes — up to 8 hours per charge and around 40 hours total with the case, versus 35 hours total for the Hentrixis. PTHTECHUS also claims roughly 3 extra hours from a 15-minute top-up.
Both use ENC with multiple microphones, so both target call clarity. The Hentrixis adds passive isolation from its sealed fit, which helps in loud rooms. PTHTECHUS leans on ENC and directional audio to keep calls clear in wind.
Yes — PTHTECHUS specifically notes the open, above-the-ear fit works alongside glasses and other accessories. In-ear buds like the Hentrixis don't conflict with glasses either, but they do block your ear canal.
The Hentrixis Earbuds. Sealed tips plus 13mm drivers give you isolation and low-end you won't get from an open design. Check the current price on Amazon for both before deciding.
