• Hidizs MS1 biggest strength: A 10.2mm dual-magnetic dynamic driver with a PU+PEEK composite diaphragm, plus tuning explicitly aimed at positional awareness for FPS and MOBA play.
• Hidizs MS1 biggest trade-off: It's a more specialized, enthusiast-oriented IEM. You're paying for tuning intent and cable upgradability, not simplicity.
• HIFI WALKER A20 biggest strength: A secure over-ear fit with soft silicone tips that stay put during long sessions, and it's dead simple to live with.
• HIFI WALKER A20 biggest trade-off: No inline mic, no Bluetooth option, and a more modest 16Ω driver spec — it's a wired-only, music-and-gaming companion, not a do-everything headset.
• Choose Hidizs MS1 if competitive gaming audio cues are your priority.
• Choose HIFI WALKER A20 if comfort, fit stability, and straightforward wired listening matter most.
The MS1-Galaxy is the pick for someone who treats audio as part of their competitive edge. Hidizs engineered it as a professional IEM, and the headline spec is that 10.2mm dual-magnetic driver paired with a PU+PEEK composite diaphragm. In plain terms, that combination is about control and detail retrieval — the kind of thing that matters when you're trying to pick out a footstep, a reload, or a distant ability cue through a busy mix. The tuning is the interesting part: Hidizs says it followed B&K HATS measurements and psychoacoustic targets to sharpen positional awareness. I can't independently verify their lab work, but the design intent is clearly aimed at gamers, not just casual listeners.
What makes it flexible is the spec sheet around the driver. At 32Ω and 108dB sensitivity, it's easy to drive straight from a phone, tablet, or laptop — no amp required to get usable volume. It runs a 3.5mm plug, and the 2-pin connector means you can swap or upgrade the cable later, which is a genuinely useful long-term feature. The silver-plated oxygen-free copper cable is there to keep signal transmission clean. There's also an inline mic version for calls and voice chat, plus a sweat-resistant shell if you game or listen during workouts.
Who should skip it? If you want the simplest possible plug-and-play earbud and don't care about cable swapping or tuning philosophy, the MS1 is more than you need. And if you specifically want a touch-control, over-ear-only design, look elsewhere. But for a gamer who wants positional detail and doesn't mind a slightly more involved setup, this is the more purpose-built tool. Check the current price on Amazon before deciding, since that's the one variable I can't speak to here.
The A20 is built around a different priority: staying comfortable and staying put. The over-ear wearing design routes the cable over the top of your ear, which does two things — it keeps the earbud anchored and it reduces cable pull when you move. That's a real quality-of-life difference during a three-hour gaming session or a long study block. The soft silicone ear tips create a seal that handles passive noise isolation, and HIFI WALKER includes three pairs in small, medium, and large so you can actually find your fit.
On the audio side, it's a 10mm dynamic driver with a 20Hz–20KHz frequency response and 16Ω impedance. That low impedance makes it very easy to drive from basically anything with a headphone jack. HIFI WALKER pitches it for deep bass and clear vocals, which is a sensible tuning for music, gaming, and studio-style listening. It's wired-only via 3.5mm, and the 2-pin cable is detachable, so you can replace it if it wears out. It ships in green.
The clear trade-off is the missing inline mic. If you need voice chat, you'll have to handle that separately. It's also wired-only — no Bluetooth mode. So who is this for? The gamer or listener who wants a secure, comfortable, isolation-friendly IEM for long wired sessions and doesn't need a mic built into the cable. Who should skip it? Anyone who wants a mic for calls or in-game comms out of the box, or anyone chasing the most aggressive positional tuning. For those buyers, the MS1 is the better fit.
Side-by-Side: Which Should You Choose?
• Best for long-session comfort and fit stability → HIFI WALKER A20. The over-ear design reduces cable pull and keeps the bud anchored.
• Best for cable upgradability and flexibility → Hidizs MS1. 2-pin detachable cable plus an inline-mic option and Bluetooth mode support.
• Best for plug-and-play simplicity → HIFI WALKER A20. 16Ω, wired 3.5mm, three sizes of tips in the box, done.
• Best for built-in mic and voice chat → Hidizs MS1. The A20 has no mic at all.
• Best for easy smartphone/laptop driving → Both work, but the A20's 16Ω is the easier load. The MS1's 32Ω is still phone-friendly.
• Best for bass-forward music listening → HIFI WALKER A20. It's tuned for deep bass and clear vocals.
• Best for a more specialized gaming tool → Hidizs MS1. More driver tech, more tuning intent, more ways to configure it.
In my opinion, if gaming audio cues are the whole point, I'd buy the Hidizs MS1. The dual-magnetic driver, the PU+PEEK diaphragm, and the gaming-focused tuning give it a clear reason to exist for competitive players, and the detachable 2-pin cable plus mic option make it more adaptable over time. I'd pick the HIFI WALKER A20 instead if comfort, fit stability, and simplicity matter more than positional precision — it's the easier earbud to live with for hours. Buy the MS1 for the edge; buy the A20 for the comfort.
FAQ
what is gaming earbuds
Gaming earbuds are in-ear monitors tuned and shaped for play — usually emphasizing positional detail so you can hear footsteps, reloads, and directional cues. Both the Hidizs MS1 and HIFI WALKER A20 fit that description, though the MS1 leans harder into positional tuning while the A20 leans into comfort and fit.
There's no universal best — it depends on what you value. In my opinion, the Hidizs MS1 is the better pick for competitive positional audio because of its gaming-focused tuning and 10.2mm dual-magnetic driver, while the HIFI WALKER A20 is the better pick if long-session comfort and a secure over-ear fit matter most to you.
what gaming earbuds are good
Good gaming earbuds need a clean, detailed sound signature, a stable fit, and low enough impedance to drive from your phone, laptop, or console controller. The MS1 runs 32Ω with a detachable 2-pin cable and an optional inline mic; the A20 runs 16Ω with an over-ear design and three sizes of silicone tips. Both qualify.
what is the best gaming earbuds for pc
For PC gaming, the Hidizs MS1 is my pick if you want positional accuracy and the option of an inline mic for voice chat, since it plugs into a 3.5mm jack on your PC or controller. The HIFI WALKER A20 works fine on PC too, but you'd need a separate mic for comms because it ships without one.
