• ETWAR B3 — biggest strength: a full wired gaming headset with a built-in 360-degree noise-isolating mic, 40mm dynamic drivers, inline volume and mute, and broad 3.5mm compatibility across PS4, Xbox One, Switch, PC and mobile.
• ETWAR B3 — biggest trade-off: it is wired only, and getting the best results across platforms may mean using the included mic splitter cable rather than a single connection.
• Tobysome QC35 — biggest strength: it upgrades Bose QC35 and QC35 II headphones into a professional headset with a flexible, detachable boom mic, an inline mute switch and a USB-C connection for modern phones and laptops.
• Tobysome QC35 — biggest trade-off: it is only a cable, so it is useless unless you already own Bose QC35 or QC35 II headphones, and it delivers no sound on its own.
• Who each pick is for: the ETWAR B3 is for someone who wants a complete headset straight out of the box; the Tobysome QC35 is for an existing Bose QC35 owner who just wants to add a microphone.
The ETWAR B3 is a self-contained headset, and that is the whole point of it. Everything you need to play and talk is in the box: the headset itself plus a 3.5mm 2-in-1 mic splitter cable for devices that separate headphone and microphone jacks. There is no app, no pairing, no charging. You plug in a 3.5mm jack and you are in.
The audio side is built around 40mm dynamic drivers with an impedance of 32 ohm and a 20 Hz to 20,000 Hz frequency range. In practice, that means it can run off a controller, a laptop or a phone without a dedicated amp. ETWAR frames the tuning around Mega Bass Surround and large magnetic speakers for picking out footsteps, bombings and other in-game cues. The microphone is described as a 360-degree sound-capture design that reduces background noise so your callouts reach teammates clearly.
Comfort is where the spec sheet gets specific. The B3 uses breathable protein ear pads and a multi-point adjustable headband, with skin-friendly faux leather for longer sessions. The earcups are over-ear, which spreads pressure around the ear instead of pressing on it. If you play for hours at a time, that matters more than any single spec.
Who should buy it: anyone who wants one wired headset that works across PS4, PS4 Pro or Slim, PSP, Xbox One, Nintendo Switch, laptops, desktops, tablets, iPads and phones. It suits younger players, console gamers on a controller, and anyone who prefers a wired connection for zero latency and no battery to think about. Who should skip it: if you already own a pair of premium headphones you love, or you need wireless freedom, the B3 is the wrong purchase. It is wired, full stop.
Tobysome QC35: Who It's For
The Tobysome QC35 is not a headset. It is the missing piece that turns one into a headset. The cable runs USB-C male on one end and 2.5mm male on the other, and that 2.5mm end fits only the Bose QuietComfort 35 II and QuietComfort 35 headphones. If you own either of those, this cable is the difference between listening to game audio and actually talking to your team.
The boom microphone is the headline feature. It is flexible, with a 120-degree adjustable gooseneck so you can angle it toward your mouth, and it is detachable, so you can pull the mic off for casual listening without a stalk dangling in front of your face. The mic element is a unidirectional cardioid design with noise-cancelling, which is exactly the right choice for voice: it favours what is in front of it and rejects more of the room around it. Tobysome describes the result as crystal clear communication that reduces background noise so colleagues, teammates and podcast listeners hear only what you want them to.
There is an inline mute switch that slides up and down, so you can cut your mic without touching your keyboard or interrupting play. The build details are sensible: a 3.9 ft (1.2 m) TPE-covered cable, oxygen-free copper inner wire, and a gold-plated 2.5mm plug that Tobysome says stays securely seated in the headset and keeps the transmission stable.
The USB-C end is what makes it current. It works with iPhone 17, Air, 16 and 15, iPad, Samsung and Android smartphones, laptops and other USB-C devices. That matters because most modern phones and thin laptops have no 3.5mm jack at all, and this cable sidesteps the dongle problem entirely.
Who should buy it: Bose QC35 or QC35 II owners who want to game, take calls, do Skype or VoIP, podcast, or join meetings using the headphones they already trust. Who should skip it: anyone without QC35 or QC35 II headphones, and anyone who wants a plug-and-play headset with nothing else to buy.
• Best for someone starting from zero → ETWAR B3. It includes the headset, the mic and the splitter cable; nothing else is required.
• Best if you already own Bose QC35 or QC35 II → Tobysome QC35. It adds voice to headphones you already have instead of replacing them.
• Best for console gaming → ETWAR B3. Native 3.5mm compatibility covers PS4, PS4 Pro or Slim, Xbox One and Nintendo Switch.
• Best for modern USB-C phones and laptops → Tobysome QC35. The USB-C jack fits iPhone 15 through 17, iPad, Samsung, Android and USB-C laptops.
• Best for a detachable, adjustable mic → Tobysome QC35. The 120-degree flexible boom comes off entirely for music-only listening.
• Best for a self-contained mute setup → ETWAR B3. The inline mic mute key and rotating volume wheel are built onto the cable.
• Best for long-session comfort out of the box → ETWAR B3. Breathable protein ear pads and an adjustable headband are designed for extended wear.
• Best for travel and commuting → Tobysome QC35. A single lightweight cable is far easier to pack than a second headset.
• Worst-case mismatch: buying the Tobysome QC35 without QC35 headphones, or buying the ETWAR B3 hoping to upgrade headphones you already love.
One practical note on cost: both items sit in very different spending brackets simply because one is a full headset and the other is a cable. I would check the current price on Amazon for whichever one you are leaning toward before committing, since that is the only variable that changes here.
My Verdict
In my opinion, the right answer depends entirely on what is already sitting on your desk. If you have no headset and want to start gaming tonight with a working mic, volume control and mute button, I would buy the ETWAR B3 — it is the complete package and there is nothing else to figure out. If you already own Bose QC35 or QC35 II headphones, I would buy the Tobysome QC35 instead, because it turns headphones you already like into a proper gaming and calling headset for far less than a new set would cost. For a blank-slate buyer, the ETWAR B3 is the safer pick.
The data sheet lists PS4, PS4 Pro or Slim, PSP, Xbox One, Nintendo Switch, laptops, computers, tablets, iPads and mobile phones. It is a wired 3.5mm headset, so anything with a 3.5mm jack is the target use case.
No. The 2.5mm end fits only Bose QuietComfort 35 and QuietComfort 35 II. It will not fit other brands or other Bose models.
Yes. The cable is positioned for gaming, business, Skype and VoIP, podcasting and taking calls on the go, and the inline mute switch works in any of those situations.
They are not really comparable. The ETWAR B3 makes sound with its own 40mm dynamic drivers. The Tobysome QC35 makes no sound at all — the audio quality you get is whatever your Bose QC35 or QC35 II headphones already deliver.
