If you want a single do-everything desktop keyboard with low-profile mechanical switches, dedicated macro keys and a volume wheel, choose Logitech G815; if you need a lightweight wireless headset for PS5, PC and everything in between, choose Razer BlackShark V3.
• Logitech G815 — biggest strength: a full-size, 104-key wired mechanical keyboard with low-profile GL Tactile switches, aircraft-grade aluminum build, 5 dedicated G-keys, per-key LIGHTSYNC RGB, dedicated media controls with an edgeless volume wheel, and a powered USB 2.0 passthrough.
• Logitech G815 — biggest trade-off: it is a desk-bound, DC-powered board at roughly 1.6 kg, with no wireless option, and the thin, tall-ish chassis needs a bit of desk space.
• Razer BlackShark V3 — biggest strength: a 270 g over-ear wireless headset with 50 mm Gen-2 TriForce drivers, a detachable 9.9 mm HyperClear cardioid mic, 2.4 GHz HyperSpeed plus Bluetooth 5.3, and a 70-hour battery.
• Razer BlackShark V3 — biggest trade-off: it's a headset, not an input device — no keyboard, no macro keys, and no wired 3.5 mm jack if you ever want a pure analog connection.
• Who each pick is for: the G815 suits desk-bound players who want one keyboard that handles gaming, macros and media at a fixed station. The BlackShark V3 suits console and laptop players who want one headset that moves between PS5, PC, Switch, Mac and phone.
The G815 is a wired, full-size mechanical keyboard built around Logitech's low-profile GL switches. The GL Tactile version has a discernible bump right at the actuation point, so you get the feel of a mechanical switch while sitting at roughly half the height of a conventional one. That lower profile changes the typing posture: your wrists sit flatter, and key travel is shorter. If you've been fighting with a chunky keyboard that forces your hands into a steep angle, this is the design argument in its favour. Logitech also offers the same board in GL Linear and GL Clicky, so the switch feel is a choice rather than a fixed spec.
The build is the other half of the story. The top plate and enclosure are aluminum, and the whole thing weighs around 1.6 kg with 104 keys — the kind of mass that keeps a board planted during fast play. Around the edges you get practical desktop furniture: five dedicated G-keys you can program per game or app profile through Logitech G HUB, dedicated media controls, and an edgeless volume wheel that lets you ride game audio without alt-tabbing. The extra USB cable powers a USB 2.0 passthrough port on its own input, so plugging in a mouse or charging a phone doesn't starve the port. Per-key LIGHTSYNC RGB works across 16.8 million colours and can sync to games, music and video, and G HUB lets you connect to third-party apps and download or share community profiles.
Buy it if you want a fixed-station keyboard that does gaming, macros and media duty in one, and you'd rather have a wired connection than manage a battery. Skip it if you need portability, want wireless, or prefer a small tenkeyless footprint — and note the 2-year warranty is a keyboard warranty, not a "replace my whole setup" promise. It pairs naturally with a Mac or Windows machine over USB.
The BlackShark V3 X HyperSpeed is a wireless over-ear headset in white, and its whole design brief is "light and connected." At 270 g with plush memory foam and fabric earcups, the weight distribution is aimed at long sessions — the kind where a heavier headset starts to press on the crown of your head. The 50 mm TriForce Gen-2 dynamic drivers are tuned for positional clarity, so footsteps and directional cues come through with an expanded soundstage rather than a wall of bass.
Connectivity is where it earns its keep. You get 2.4 GHz HyperSpeed via a USB dongle for low-latency play, plus Bluetooth 5.3 for phone, laptop and casual listening — no 3.5 mm jack at all, so this is a wireless-only headset by design. On PS5 you get advanced surround processing, and on PC you can unlock 7.1.4 surround for positional accuracy. The mic is a detachable 9.9 mm HyperClear cardioid unit with a unidirectional pickup pattern, which means more of your voice and less of the room; pulling it off turns the headset into a plain pair of wireless headphones for commuting or calls.
Razer rates the battery at 70 hours, which is the sort of number that changes how you use a headset — you stop thinking about charging it every night. Controls are push-button, and sound isolation comes from the closed earcups rather than active noise cancellation. Buy it if you game across PS5, PC, Switch, Mac and phone and want one headset that follows you between them. Skip it if you need a wired analog connection, want active noise cancellation, or specifically need a keyboard.
• Best for typing feel and low-profile switches → Logitech G815. GL Tactile gives a real bump at a shorter height, with Linear and Clicky variants if you prefer.
• Best for desktop productivity shortcuts → Logitech G815. Five programmable G-keys plus a volume wheel and media controls, all configurable per app in G HUB.
• Best for multi-device flexibility → Razer BlackShark V3. 2.4 GHz dongle plus Bluetooth 5.3 covers PS5, PC, Mac, Switch and smartphone.
• Best for long-session comfort → Razer BlackShark V3. 270 g with memory foam and fabric earcups is built for marathon sessions.
• Best for a cable-free, low-latency setup → Razer BlackShark V3. No keyboard cable, no passthrough cable, just a dongle.
• Best for a permanent, no-battery desk setup → Logitech G815. DC-powered over USB, so there's nothing to charge and nothing to pair.
• Best for voice chat clarity → Razer BlackShark V3. The detachable cardioid mic's unidirectional pattern is aimed at isolating your voice.
• Best for RGB customisation → Logitech G815. Per-key LIGHTSYNC across 16.8 million colours with community profile sharing.
• If you can only buy one → decide by your bottleneck. No keyboard? Get the G815. No headset? Get the BlackShark V3. They don't overlap.
In my opinion, the Razer BlackShark V3 is the easier recommendation for most people, because it solves a problem almost every platform has in common: audio and comms that work everywhere, wirelessly, for 70 hours at a time. The G815 is the better product for a narrower job — a permanent desk where you want mechanical feel, macro keys and media control in one slab of aluminum. If your setup is already complete except for audio, take the BlackShark V3. If you're building a desktop battlestation from scratch and the keyboard is the missing piece, the G815 is the one I'd put my money on. Either way, check the current price on Amazon before you commit — both are frequently discounted, and the value case shifts with the deal.
FAQ
Yes. It connects over 2.4 GHz HyperSpeed via a USB dongle or Bluetooth 5.3, and Razer lists PS5, PC, Mac, Nintendo Switch and smartphone support. On PC you can unlock 7.1.4 surround sound for positional accuracy.
No. The G815 is USB-wired and DC-powered, which is why it has no battery to manage. It includes a second dedicated USB cable to feed the USB 2.0 passthrough port at full power and data speed.
Yes. The 9.9 mm HyperClear cardioid mic is detachable, so you can remove it for listening or travel and reattach it for voice chat.
That depends on what you're missing. Both carry a 2-year warranty, and both are regularly discounted — check the current price on Amazon for each before deciding, since the better deal tends to flip.
