How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want gaming-grade low-latency audio with real noise cancellation, choose Razer Hammerhead True; if you need all-day open-ear comfort with much longer battery life, choose Sony.
• Razer Hammerhead True — biggest strength: A gaming-first design with 60ms low-latency mode, THX-certified tuning, and advanced hybrid ANC that actively blocks outside noise.
• Razer Hammerhead True — biggest trade-off: Battery life tops out at around 4 hours per charge in the buds, stretching to about 20 hours total with the case.
• Sony — biggest strength: Up to 22 hours of battery life with quick charging, plus an open-ring design that keeps you aware of your surroundings.
• Sony — biggest trade-off: The open-ear design lets sound in by nature, so it won't seal off a noisy room the way a closed in-ear bud can.
• Who Razer is for: Competitive gamers and anyone who wants to shut the world out and react faster in-game.
• Who Sony is for: Commuters, remote workers, and people who want to wear earbuds for hours without ear fatigue.
The Hammerhead True Wireless Pro is built around one idea: latency. That 60ms figure matters. When you activate Gaming Mode, audio and video sync up more tightly, which is exactly what you want in a shooter or a rhythm game where a quarter-second of lag means a missed shot or a blown combo. Most casual earbuds don't even advertise a latency number. Razer does, and it's the headline for a reason.
Then there's the noise cancellation. This is a hybrid ANC system, meaning it samples noise from outside and inside the earbud and generates anti-noise to cancel it. In practice, that's the kind of ANC that actually works on a plane, a bus, or a loud office. Combine it with the in-ear seal and Comply foam tips, and you get real passive isolation on top of the active stuff. You also get Quick Attention Mode, which pipes outside sound back in when you need to hear a cashier or cross a street.
Audio-wise, the buds are THX certified, which is a cinematic-audio standard, not a marketing sticker. Razer tuned them for a rich, balanced soundstage across movies, music, and games. Hybrid drivers handle the frequency spread from 20Hz to 20kHz, and the 18-ohm impedance is low enough that any phone can drive them. Fit is customizable too — Comply foam tips plus six extra silicone sizes, so most people can find a seal.
Who should buy it? Gamers, first and foremost. Also anyone who flies or commutes in genuinely loud environments and wants the noise gone. Who should skip it? If you plan to wear earbuds for a full eight-hour workday, the roughly 4-hour-per-charge bud life will have you docking them in the case more than you'd like. And if you hate the plugged-ear feeling, the in-ear seal here is the opposite of what you want.
The Sony LinkBuds Open takes a completely different philosophy. Instead of sealing your ear canal, it uses an open-ring driver design that leaves your ear open to the world. The 11mm ring-shaped driver fires sound at your ear without plugging it, which means you can hear traffic, a coworker, or your own surroundings while music plays. For city commuting, biking, or an office where people tap you on the shoulder, that's a genuine feature, not a compromise.
Comfort is the other pillar. Sony developed what it calls Air Fitting Supporters — a soft, ergonomic support structure that holds the bud in place without pressing into your canal. The result is a bud you can wear for hours without the ache that closed in-ear designs eventually cause. At 41 grams for the set, they're light, and the rounded-tip shape is meant to sit naturally rather than jam in.
Battery is where Sony runs away with it. You get up to 22 hours of playback, and quick charging gives you up to 60 minutes of playback from a 3-minute charge. That's the kind of number that changes how you use earbuds — you stop thinking about the charger. A short top-up before a commute is enough to cover the whole trip.
Sound is handled by Sony's Integrated Processor V2 and that 11mm ring driver, tuned for clear mid-to-high frequencies and well-balanced audio. The 16-ohm impedance keeps them easy to drive. One thing to flag: this listing is a renewed, manufacturer-refurbished unit that comes with all original accessories and a 90-day limited hardware warranty. That's a shorter coverage window than a new pair, so factor that in.
Who should buy it? Anyone who wears earbuds all day, wants to stay aware of their environment, or hates the plugged-ear sensation. Who should skip it? If you need to block out a noisy train or a loud open office, the open design works against you. And if you want the longest possible warranty, renewed status is worth weighing.
• Best for gaming and low latency → Razer Hammerhead True. The 60ms Gaming Mode is the whole point.
• Best for blocking out noise → Razer Hammerhead True. Hybrid ANC plus a sealed in-ear fit is the combo that silences a room.
• Best for battery life → Sony. Up to 22 hours versus roughly 20 hours total with the Razer case.
• Best for all-day comfort → Sony. The open, supported fit avoids the ear fatigue of a sealed bud.
• Best for staying aware of your surroundings → Sony. The open-ring design keeps you connected to the world; Razer does it only on demand via Quick Attention Mode.
• Best for cinematic, sealed-in sound → Razer Hammerhead True. THX certification and a proper seal give you a more immersive listen.
• Best for quick top-ups → Sony. A 3-minute charge buys up to 60 minutes of playback.
• Best for warranty peace of mind → Razer. A 2-year manufacturer warranty beats Sony's 90-day renewed coverage.
In my opinion, the right pick comes down to one question: do you want the world shut out, or kept in? If you game, fly, or work somewhere loud, I'd buy the Razer Hammerhead True — the 60ms latency mode, hybrid ANC, and THX tuning make it the more capable tool for focused listening, and the 2-year warranty is the cherry on top. If you wear earbuds for hours and want to stay aware and rarely charge, I'd buy the Sony LinkBuds Open. My own pick leans Razer for the gaming and noise-cancelling edge, but Sony wins outright on battery and comfort. Check the current price on Amazon before you commit, since that's the one thing specs can't tell you.
For gaming, yes. Razer's 60ms low-latency Gaming Mode is designed specifically to sync audio and video during competitive play, and THX certification targets cinematic sound. Sony's LinkBuds Open is tuned for balanced everyday listening, not low-latency gaming.
Sony. The LinkBuds Open offers up to 22 hours of battery life with quick charging, while the Razer Hammerhead True delivers up to 4 hours per charge and about 20 hours total with its charging case.
Yes, it lists active noise cancellation, but the open-ring design intentionally keeps your ear open to your surroundings, so it won't isolate you from noise the way Razer's sealed in-ear fit and hybrid ANC will.
It's a manufacturer-refurbished unit that includes all original accessories and a 90-day limited hardware warranty. If you want a longer warranty, that's a real consideration — Razer's new unit carries a 2-year manufacturer warranty.
