How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired USB-C earbud tuned for clear calls, hi-res listening and long comfort sessions, choose 1MORE P20; if you need a gaming-first in-ear monitor with app-based EQ tuning, a swappable cable and a resin shell built for marathon sessions, choose EPZ G10. Both sit in the same 10mm driver class, but they aim at completely different listeners.
• 1MORE P20 — biggest strength: a 10mm diamond-like carbon (DLC) driver in an aluminum alloy chamber, paired with a MEMS microphone and AI ENC noise isolation for calls.
• 1MORE P20 — biggest trade-off: it is a fixed-cable, USB-C only design with button controls and passive sound isolation — no app tuning, no detachable cable, no hybrid noise cancellation.
• EPZ G10 — biggest strength: a 10mm LCP+PU composite dynamic driver inside a 3D-printed resin cavity, plus detachable 0.78mm 2-pin cable, EQ adjustment (Type-C version) and hybrid noise cancellation.
• EPZ G10 — biggest trade-off: the tuning software only works on the Type-C version, the 3.5mm version is analog with no EQ, and it ships without bundled media, so you supply your own source and setup.
• Who each pick is for: the P20 is for commuters, students and remote workers who want a plug-and-play USB-C bud with a strong mic; the G10 is for gamers and IEM-curious listeners who want tuning control and a replaceable cable.
The P20 is the simpler, more appliance-like product of the two. Its headline part is a 10mm diamond-like carbon driver — DLC is a stiff diaphragm material, and stiffness is what usually translates into tight, defined bass and cleaner detail rather than a soft, bloated low end. 1MORE houses that driver in aluminum alloy chambers, which the spec sheet credits with added sound stability. Impedance is 32 ohm, a common, easy-load figure that most phones, tablets and laptops can drive without a dongle or amp.
Connectivity is the real story here. This is a USB-C wired earphone, so it plugs straight into modern smartphones, tablets and iPads with no setup. There is no 3.5mm option on the P20 — the product information lists a 3.5mm jack field, but the marketed connectivity is USB-C, so treat the USB-C port as the one you'll actually use. Controls are physical push buttons on the cable for volume and playback, plus a mic mute function — a small detail that matters a lot if you spend your day on video calls and want a one-press way to cut your own mic.
The microphone is a MEMS type with AI ENC noise isolation. MEMS mics are the small, stable, low-noise kind used in decent headsets, and ENC processing is aimed at stripping background noise out of your voice before it reaches the other side of the call. That combination — MEMS plus ENC plus a mute button — is the P20's clearest reason to exist. The 45-degree angled nozzle is a comfort and isolation feature: angled buds tend to sit deeper and more securely in the ear canal, which both blocks ambient noise passively and reduces fatigue over long sessions.
Who should buy it: anyone who wants one wired pair for work, study and commuting, plugs into USB-C, and cares most about call clarity, passive isolation and not fiddling with settings. The 1-year manufacturer warranty and adult age range round it out as a straightforward daily driver.
Who should skip it: if you want to EQ your sound, swap cables when one wears out, or play competitive games where positional accuracy is the whole point, the P20's fixed cable and button-only control scheme will feel limiting.
The G10 is aimed at a narrower, more enthusiastic buyer: the gamer and the IEM hobbyist. Its shell is made with DLP 3D printing in skin-friendly resin. That is not marketing fluff — resin shells can be printed into shapes that are hard to mold, and the result is typically a very light, low-pressure fit that stays comfortable through long sessions. The spec sheet leans on exactly that: featherlight comfort and a seamless fit for marathon gaming.
Inside sits a 10mm LCP+PU composite dynamic driver. LCP (liquid crystal polymer) is a stiff, fast diaphragm material, and pairing it with PU gives the design a blend of punch and control. EPZ describes the result as clear, accurate sound positioning with powerful bass and a broad, natural soundstage — in plain terms, a tuning aimed at hearing where footsteps and shots come from, not just thumping.
The G10's flexibility is its second selling point. The cable is detachable via a 0.78mm 2-pin connector, so a worn cable can be replaced instead of writing off the whole earphone, and you can swap to another compatible cable. There's an in-line control and microphone for calls and in-game chat. The build is described as waterproof, which is a meaningful durability claim in a product this small. And impedance is again 32 ohm, with 100 dB sensitivity — an easy load that most sources can drive.
Then there's the version split, which is the single most important thing to understand before buying. The Type-C version has a built-in DAC and supports EQ adjustment through the tuning driver software; the 3.5mm version is analog, works with controllers, PCs and anything with a 3.5mm jack, and does not support tuning. Both share the same earpieces and tuning. Also note the manufacturer's own caveat: the tuning driver must be downloaded from the official EPZ site, and the 3.5mm interface doesn't support tuning at all.
Who should buy it: gamers on PC or handhelds who want a Type-C digital connection and EQ control, or anyone who wants a repairable IEM with a replaceable cable and hybrid noise cancellation. The 3.5mm version suits controller and console players who just want a plug-in analog set.
Who should skip it: if you want zero setup, no software downloads, and a single cable you never think about, the G10 asks for more involvement than the P20.
• Best for call clarity and mic control → 1MORE P20. MEMS mic, AI ENC noise isolation and a dedicated mic mute button.
• Best for gaming positioning and tuning → EPZ G10 (Type-C). LCP+PU driver plus app-based EQ adjustment.
• Best for plug-and-play simplicity → 1MORE P20. USB-C in, no software, no setup.
• Best for repairability and cable swapping → EPZ G10. Detachable 0.78mm 2-pin cable.
• Best for long-session comfort → EPZ G10. 3D-printed skin-friendly resin shell built for marathon sessions; the P20 counters with a 45-degree angled nozzle that reduces fatigue and blocks ambient noise.
• Best for noise handling → EPZ G10. Hybrid noise cancellation versus the P20's passive sound isolation.
• Best for analog devices (controllers, older PCs) → EPZ G10 in 3.5mm. The P20 is USB-C only.
• Best for a set-and-forget daily driver → 1MORE P20. Button controls, aluminum chambers, one cable, done.
If I had to pick one for myself, I'd take the 1MORE P20. In my opinion it wins on the thing most people actually do all day — take calls and listen on a phone or laptop — because the MEMS mic, AI ENC and mic mute button solve a real problem, and the aluminum-housed 10mm DLC driver with a 45-degree angled fit is a sensible, low-fuss package. I'd recommend the EPZ G10 instead if gaming is your priority, or if you specifically want EQ tuning and a cable you can replace. It's the more capable, more configurable earphone — just be sure you're buying the Type-C version if tuning matters to you.
FAQ
A 6mm driver can sound perfectly fine — smaller diaphragms tend to suit treble and compact, lightweight buds. The trade-off is usually less low-end weight and output. That's the main reason both products in this comparison sit at 10mm rather than 6mm: more surface area for bass and dynamics.
Yes — 10mm is a sweet spot for in-ear models. It's large enough for meaningful bass and a broad soundstage, yet small enough to fit an in-ear nozzle comfortably. The P20's 10mm DLC driver and the G10's 10mm LCP+PU driver both fall in that range.
For gaming I'd point you to the EPZ G10, especially the Type-C version. Its LCP+PU composite driver is tuned for accurate sound positioning, it supports EQ adjustment, and it has a detachable cable and hybrid noise cancellation. The P20 is the better pick for calls and everyday listening.
