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 over-ear headset for computer gaming with a boom mic, inline volume and mute, and a comfy fit for marathon sessions, choose ETWAR B3; if you need ultra-light in-ear buds with a USB-C plug, a detachable boom mic, and boosted bass for computer and mobile play, choose SpinBot BattleBudz C30.
• ETWAR B3 biggest strength: Over-ear design with breathable protein ear pads, a 360-degree noise-isolating boom mic, and a rotating volume dial plus one-click mute — built for long desktop sessions.
• ETWAR B3 biggest trade-off: It's wired only, with a 3.5mm jack and no wireless tech, so you're tethered to whatever you plug into.
• SpinBot BattleBudz C30 biggest strength: Just 24g with a 1.2m tangle-free cable, 12mm gaming-tuned drivers for boosted bass, and a USB-C plug that needs no adapters.
• SpinBot BattleBudz C30 biggest trade-off: In-ear fit and a Type-C-only connection mean older gear with a 3.5mm jack is out of luck.
• Who each is for: Pick the ETWAR B3 if you want an over-ear, mic-forward headset for a desktop PC; pick the BattleBudz C30 if you want featherweight in-ears you can move between a laptop and a phone.
The ETWAR B3 is a wired, over-ear gaming headset built around a single 3.5mm jack. That jack is the whole story here: it carries both audio and mic, and ETWAR ships a 2-in-1 splitter cable in the box so you can route headphone and mic separately on a desktop that wants two plugs. If you've ever fought with a headset that only half-worked on a PC, that splitter is the detail that matters.
On the audio side, the B3 uses dynamic drivers with a 20Hz–20,000Hz frequency range and 32-ohm impedance. That's an easy load for a laptop or motherboard jack to drive, so you don't need an amp to get decent volume. ETWAR leans hard into "Mega Bass" and footstep clarity in its marketing, and the large magnetic speaker units are meant to raise sensitivity so quiet in-game cues — reloads, footsteps, distant explosions — come through instead of getting buried.
The mic is the other half of the pitch. It's a noise-isolating boom that captures from all directions and is designed to cut down background noise so your callouts land cleanly. There's a rotating volume wheel on the cable and a one-click mic mute, which is exactly the kind of thing you want mid-match without alt-tabbing.
Who should buy it: PC and console players who want one wired headset with a real boom mic, physical volume and mute controls, and over-ear comfort for hours at a desk. Who should skip it: anyone who wants wireless freedom, or who games on a phone or tablet with no 3.5mm jack — this headset has no wireless technology and no USB-C option.
SpinBot BattleBudz C30: Who It's For
The BattleBudz C30 goes the opposite direction: it's an in-ear, wired earphone that ends in a USB-C plug. No adapter, no dongle — you push it straight into a USB-C laptop, tablet, or phone and you're live. For anyone whose computer dropped the headphone jack years ago, that's a real convenience.
What stands out is the mic setup. SpinBot gives you two: a detachable boom mic for focused team chat, and an inline mic for casual calls or travel when you don't want the boom hanging off your ear. The boom mic is omnidirectional with a sensitivity spec of -42 ± 6dB and 2.2 Kohm impedance, tuned to pick up your voice from any direction while keeping background noise low. Being able to pop the boom off and switch to the inline mic is genuinely useful if you use one pair of buds for both gaming and a commute.
The drivers are 12mm, custom-tuned for gaming with boosted bass, clear mids, and precise highs. SpinBot's claim is spatial awareness — hearing footsteps and reloads before you see them. In-ears sit right in the ear canal, so bass tends to hit harder than it does on an over-ear at the same volume, and the "deep bass" angle is part of the appeal here.
Weight is the headline number: 24g. On a 1.2-meter tangle-free cable, that's about as light as a wired gaming audio setup gets. Controls sit inline too — a mute switch, a volume slider, and a function button for play/pause.
Who should buy it: gamers who want featherweight in-ears, a USB-C connection that works across a modern laptop and phone, and the flexibility of swapping between a boom mic and an inline mic. Who should skip it: anyone who prefers over-ear isolation and padding, or who still games on hardware with only a 3.5mm jack — this is USB-C only.
• Best for over-ear comfort on a desktop → ETWAR B3. Breathable protein pads and an adjustable headband are made for long stretches at a keyboard.
• Best for all-day lightness → SpinBot BattleBudz C30. At 24g on a tangle-free cable, you'll forget you're wearing them.
• Best for deep bass → SpinBot BattleBudz C30. The 12mm gaming-tuned drivers are explicitly built for boosted low end.
• Best for a mic you can rely on for callouts → ETWAR B3. A 360-degree noise-isolating boom mic plus one-click mute is the more dedicated comms setup.
• Best for mic flexibility on the move → SpinBot BattleBudz C30. Detach the boom and fall back to the inline mic for calls and travel.
• Best for older PCs and consoles → ETWAR B3. The 3.5mm jack and included 2-in-1 splitter cover desktops, PS4, Xbox One, Switch, and more.
• Best for modern USB-C laptops and phones → SpinBot BattleBudz C30. Plug-and-play Type-C with no adapters.
• Best for physical volume control → ETWAR B3. A rotating volume wheel beats hunting for a slider when a match is loud.
For computer use at a desk, I'd buy the ETWAR B3. The over-ear build, breathable pads, rotating volume wheel, one-click mute, and included splitter cable make it the more natural fit for long PC sessions where you're talking to teammates and want a proper boom mic. In my opinion, if comfort and comms matter more than portability, that's the pick. I'd only steer you to the SpinBot BattleBudz C30 if you want ultra-light in-ears, deep bass, and a USB-C plug you can move between a laptop and a phone.
No. The ETWAR B3 is a wired headset with a 3.5mm jack and no wireless technology. You stay plugged into your computer, console, or phone.
Yes, as long as your computer has a USB-C port. They plug straight in with no adapter, which makes them a good fit for modern laptops and USB-C phones.
The BattleBudz C30 is the more bass-forward of the two on paper, thanks to 12mm gaming-tuned drivers with boosted bass. The ETWAR B3 uses larger dynamic speaker units aimed at clarity and footstep detail rather than pure low-end thump.
Both are designed with long sessions in mind, just differently. The ETWAR B3 relies on breathable over-ear protein pads and an adjustable headband to cut heat and fatigue; the BattleBudz C30 keeps things light at 24g so there's barely any pressure on your ears.
