• Delton 10X – biggest strength: A true headset design — rotating noise-isolating boom mic, on-ear cushion, T-pad grip and call-control buttons built for talking all day.
• Delton 10X – biggest trade-off: It's a monaural on-ear headset, so it's a communication tool first; music sounds like it's coming from one ear, and the plastic build is functional rather than premium.
• CHENRUIDA M75 – biggest strength: Open-ear, featherweight earbuds (about 7 g each) with a charging case and a claimed 80 hours of total playtime — made for movement and long listening sessions.
• CHENRUIDA M75 – biggest trade-off: Open-ear sound leaks and doesn't seal, and that tiny in-line mic is not a substitute for a boom mic when you're on calls all day.
• Who each is for: Buy the Delton 10X if your job is calls. Buy the CHENRUIDA M75 if your day is music, podcasts, running and cycling.
The Delton 10X is unapologetically a work headset. You wear it on one ear, the mic arm rotates a full 270 degrees, and that rotation is the whole point: you can move the boom to your mouth on either the left or right side and keep it exactly where your voice is. The mic is noise-isolating, so the design intent is to grab your voice and reject the room around you. If you've ever taken a call from a kitchen, a shared office or the cab of a truck, you know why that matters.
Battery is the other headline. Delton rates the 10X at roughly 15–18 hours of talk time and about 200–220 hours of standby, with a 1.5-hour charge over USB. In practical terms, that's a full shift plus overtime without hunting for a cable. Bluetooth 5.0 handles pairing, and the headset can hold two Bluetooth devices at once, so you can jump between a laptop and a phone without re-pairing every time. Range is listed at 30 feet (the description says 33 ft / 10 m), which is enough to stand up, stretch or walk to the printer mid-call.
Comfort is handled by an adjustable headband, an enlarged cushioned ear pad and a T-pad that spreads weight across the top of your head instead of pressing on one spot. Controls are on the headset: a multi-function button for answer/end plus volume, playback and mic mute. Audio specs are a 32-ohm dynamic driver with a 20 Hz–20 kHz range — fine for speech and casual media.
Who should buy it: call center staff, remote workers, truck drivers, receptionists, anyone who lives in meetings apps on a computer or laptop. Who should skip it: if you mainly want music in both ears, or you want earbuds you can wear running, this isn't that product. It's mono, on-ear, and black plastic — a tool, not a fashion piece.
The CHENRUIDA M75 is the opposite philosophy. These are open-ear true wireless earbuds that sit outside the ear canal rather than plugging it. Each bud weighs roughly 7 grams and uses an ABS shell with a skin-friendly finish, so the design goal is "forget you're wearing them." Open-ear also means you keep situational awareness — traffic, a training partner, a doorbell — which is exactly why this shape shows up in running and cycling.
Battery is where the M75 shines on paper: about 8 hours per bud, and up to 80 hours total when you rotate one earbud at a time through the charging case. The case itself recharges over USB-C and takes about 1.5 hours. CHENRUIDA's own notes even suggest not wearing them continuously and docking them between sessions, which fits the take-turns pattern nicely.
Sound is handled by double-layer diaphragm dynamic drivers with a 16-ohm impedance, tuned for strong bass, clear mids and bright treble. Connectivity is Bluetooth 6.0 with a stated range up to 15 meters (about 35 ft), low-latency transmission, and two modes: binaural stereo or mono, where you use just the left or right earbud. Controls are touch-based — one button for play/pause, volume and calls — and the buds auto power on and connect when you lift them out of the case. Noise handling is listed as active, environmental and passive noise cancellation, though with an open-ear fit, don't expect the isolation of a sealed in-ear bud.
Who should buy it: runners, cyclists, gym-goers, students and commuters who want music and podcasts for hours without ear fatigue, plus anyone who wants one earbud in for background audio. Who should skip it: if your day is back-to-back client calls and clear voice pickup is the priority, the M75's in-line mic and open fit are the wrong tool. That's what the Delton is for.
• Best for all-day calls and voice clarity → Delton 10X. A rotating noise-isolating boom mic beats a tiny earbud mic every time.
• Best for long listening sessions and workouts → CHENRUIDA M75. Open-ear, ~7 g per bud, and a case that stretches playtime to a claimed 80 hours.
• Best for left/right flexibility on calls → Delton 10X. The 270-degree mic arm and adjustable headband let you wear it on either ear.
• Best for staying aware of your surroundings → CHENRUIDA M75. Open-ear design doesn't seal your canal, so traffic and ambient sound still reach you.
• Best for switching between two devices → Delton 10X. It can pair with two Bluetooth devices at once, handy for laptop-plus-phone workdays.
• Best for stereo music → CHENRUIDA M75. Binaural mode gives you both channels; the Delton is monaural by design.
• Best for a single-ear, low-profile setup → CHENRUIDA M75. Mono mode lets you run one bud and pocket the other.
• Best for desk-based meeting apps → Delton 10X. Call control, mic mute and volume live on the headset, right where your hand already is.
In my opinion, these two barely compete — they solve different problems, so pick by your day, not by specs alone. If you're on calls for a living, I'd buy the Delton 10X: the boom mic, dual-device pairing and 15–18 hour talk time are exactly what a work headset should be. If your priority is music, running and hours of comfortable listening, I'd buy the CHENRUIDA M75. If you can only justify one, ask yourself which you do more — talking or listening.
FAQ
CHENRUIDA rates each bud at about 8 hours and the total with the charging case at up to 80 hours when you rotate buds. The case charges in roughly 1.5 hours over USB-C. Real numbers will vary with volume and use.
For your voice on a call, the Delton 10X — its noise-isolating boom mic is designed to focus on you. For blocking out the world around you, neither is a sealed in-ear; the M75 lists active and passive noise cancellation, but open-ear designs inherently let more sound in.
