If you want a full-size over-ear gaming headset with big drivers and a boom mic for PC, PlayStation or Switch, choose Amazon Renewed Razer BlackShark V2; if you need tiny wired USB-C earbuds that plug straight into a phone, tablet or laptop with no headphone jack, choose ACANDYA USB C Earbuds. These two share almost nothing except a 3.5mm-to-USB-C style of "wired audio" idea — one is a desk-and-console headset, the other is a pocketable everyday pair. Here's how I'd split them.
• Amazon Renewed Razer BlackShark V2 — biggest strength: over-ear design with 50 mm Triforce titanium drivers, software-enabled 7.1 surround on Windows, and a noise-isolating cardioid boom mic built for voice chat.
• Amazon Renewed Razer BlackShark V2 — biggest trade-off: it's a renewed unit (professionally inspected and tested, sold under the Amazon Renewed Guarantee), it's wired to a 3.5 mm jack, and 7.1 surround only works on Windows 10 64-bit.
• ACANDYA USB C Earbuds — biggest strength: a USB-C plug that works with a huge list of phones, tablets and laptops that dropped the 3.5 mm jack, plus inline mic, remote, three ear tip sizes and a storage case.
• ACANDYA USB C Earbuds — biggest trade-off: in-ear buds can't match a 50 mm over-ear driver for sheer scale, and USB-C-only means older 3.5 mm gear is out of the question.
• Choose the Razer if you game at a desk or on a console and want positional audio plus a real boom mic.
• Choose the ACANDYA if you want a cheap-to-replace, toss-in-a-bag pair for calls, music and video on a modern USB-C device.
The BlackShark V2 X is a gaming headset first and everything else second, and the spec sheet says so out loud. The headline part is the 50 mm dynamic driver, split into three sections — Razer calls it Triforce titanium — so highs, mids and lows get tuned separately instead of one flat response. That's the difference you feel in footsteps, reload sounds and directional cues in a shooter. On top of that, the driver is rated 32 ohm across a 20 Hz–20,000 Hz range, which is an easy load for a PC, laptop, controller or handheld — no amp needed.
The second half of the pitch is the mic and the comfort. The cardioid mic is designed to reduce background and ambient noise, which is exactly what you want if you're on voice chat in a room with a fan, a keyboard or a TV in the background. The ear cushions are oval, memory foam, gel-infused, which is Razer's way of saying "long sessions without heat and pressure building up." Weight is listed at 240 g, which is light for an over-ear, and the whole thing is a wired 3.5 mm connection with an inline volume control. If you're on Windows 10 64-bit, you can enable software-based 7.1 surround for positional audio; that feature is tied to that OS.
Who should buy it: PC, PS4 and Switch players who want one headset for both game audio and chat, and who are fine with a wire. Also anyone who wants over-ear isolation rather than something stuffed in their ear canal for hours.
Who should skip it: iPhone and modern Android owners with no 3.5 mm port — this is a 3.5 mm headset, so you'd need an adapter. Also skip it if you want something you can fold into a pocket, or if you need surround sound on macOS or a console rather than Windows. And because it's a renewed listing, go in understanding you're buying a professionally inspected and tested pre-owned unit backed by the Amazon Renewed Guarantee, with a 90-day limited warranty noted on the sheet — not a brand-new sealed box.
The ACANDYA pair solves one specific modern problem: your device has a USB-C port and no headphone jack. The compatibility list is genuinely long — recent iPhone models, the Galaxy S and Note families, Tab tablets, Pixel, OnePlus, iPad 10th gen, iPad Air and Pro, and Motorola devices, plus any USB-C device without a 3.5 mm port. That's the whole reason this product exists, and it's the reason it's the right pick for a lot of people who'd otherwise be shopping for dongles.
Inside, you get a 32 ohm dynamic driver with the same 20 Hz–20,000 Hz range as the Razer, but in an in-ear shell with aluminum enclosure material. There's a DAC chip on board, which matters with USB-C audio because the digital-to-analog conversion has to happen somewhere — built into the buds is better than hoping your phone handles it well. The cable is 1.2 m, which is a sensible length for a phone in your pocket or a tablet on a tray table. Inline mic and remote handle calls, track skipping and volume, and the button controller is on the cable.
Fit is where these earn their keep. You get an ergonomic in-ear design with three ear tip sizes — medium pre-installed — so you can actually seal your ear canal and get the noise isolation the listing promises. A proper seal is what gives small buds their bass; a bad seal makes any earbud sound thin. There's also a storage case included, which is a small thing that keeps a pair alive for years.
Who should buy it: anyone with a USB-C phone, tablet or laptop who wants wired audio without charging anything, wants a mic for calls, and wants something light enough (0.08 kg) to forget about. Students, commuters, people who take calls on an iPad — this is squarely aimed at them. It's also listed for adults and youth, so it's a reasonable second pair for a kid with a USB-C tablet.
Who should skip it: desktop gamers who want a boom mic and positional surround, anyone still using 3.5 mm-only gear, and listeners who specifically want the big, roomy presentation of an over-ear. In-ear isolation is good, but it is not the same experience.
• Best for gaming and voice chat → Amazon Renewed Razer BlackShark V2. The cardioid noise-isolating mic and 50 mm drivers are built for exactly this.
• Best for positional audio in shooters → Amazon Renewed Razer BlackShark V2, with the caveat that software 7.1 is Windows 10 64-bit only.
• Best for phone and tablet use → ACANDYA USB C Earbuds. USB-C plug, no adapter, works across a very wide device list.
• Best for long-session comfort → Amazon Renewed Razer BlackShark V2. Gel-infused memory foam over-ear cushions at 240 g versus in-ear tips.
• Best for portability → ACANDYA USB C Earbuds. 0.08 kg, 1.2 m cable and an included storage case.
• Best for fit customization → ACANDYA USB C Earbuds, thanks to three ear tip sizes.
• Best for PC/PS4/Switch wired setups → Amazon Renewed Razer BlackShark V2, via its 3.5 mm jack.
• Best for buyers wary of used gear → ACANDYA USB C Earbuds, since the Razer here is a renewed unit rather than new stock.
In my opinion, these aren't really competitors — they're answers to two different questions, and the honest move is to pick based on your device and your main activity. If you game on PC or console and talk to people while you do it, I'd buy the Amazon Renewed Razer BlackShark V2: the 50 mm drivers, the noise-isolating boom mic and the memory foam cushions are a much better match for that job, and the renewed condition is a trade-off I'd accept given the Amazon Renewed Guarantee. If your daily driver is a USB-C phone, tablet or laptop and you mainly want music, video and calls, I'd buy the ACANDYA USB C Earbuds — the compatibility list alone saves you a pile of dongle headaches. Neither one wins outright; your port decides.
It's a renewed product. It was returned or traded in, then professionally inspected and tested by Amazon-qualified suppliers to work and look like new, and it's covered by the Amazon Renewed Guarantee with a 90-day limited warranty noted on the listing.
Yes — the compatibility list covers recent iPhone models, the Galaxy S and Note lines, Tab tablets, Pixel, OnePlus, iPad and Motorola, plus any USB-C device without a 3.5 mm port. The one rule is that your device needs USB-C, not a headphone jack.
Not directly. It's a 3.5 mm wired headset, so a jack-less phone would need an adapter. The ACANDYA buds are the simpler choice if USB-C is all you have.
For calls at a desk or in a game lobby, I'd lean toward the Razer's cardioid noise-isolating boom mic — it's positioned near your mouth, which helps it reject room noise. For calls on the move, the ACANDYA's inline mic is the more practical option since it plugs straight into your phone.
