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, no-fuss headset you can plug into practically anything and wear for hours without noticing it — a genuinely comfortable Bluetooth-free pick for office desks with a 3.5 mm jack — choose Creative Sound Blaster Blaze; if you need wireless freedom, adaptive noise cancelling and a battery that outlasts your workweek, choose JBL Live 670NC.
• Creative Sound Blaster Blaze — biggest strength: wired 3.5 mm connection that works with PC, Mac, PS5, PS4 and Xbox, plus a removable noise-cancelling mic and an in-line remote with a cable clip. At 187 g it's very light for an over-ear headset.
• Creative Sound Blaster Blaze — biggest trade-off: it's wired only. There's no Bluetooth, no active noise cancelling and no battery, so your cable and your device's analog jack define where you can use it.
• JBL Live 670NC — biggest strength: True Adaptive Noise Cancelling with Smart Ambient, up to 65 hours of listening (50 hours with ANC on), 5-minute fast charging for 4 more hours, multipoint Bluetooth 5.3 and built-in voice assistant access.
• JBL Live 670NC — biggest trade-off: it's an on-ear design with no analog jack at all, so anything without Bluetooth is off the table, and on-ear cups sit on the ear rather than around it.
• Pick the Creative Sound Blaster Blaze if your office setup is a desk, a fixed workstation and a cable you don't mind. Pick the JBL Live 670NC if you move between rooms, take calls wirelessly and want the room to go quiet on command.
The Sound Blaster Blaze V2 is a gaming-oriented over-ear headset built around one simple idea: plug it into anything with an analog jack and it works. PC, Mac, PS5, PS4, Xbox — the 3.5 mm connection covers all of them. That makes it an unusually low-drama piece of kit. No pairing, no charging, no app, no latency to think about. You sit down, plug in, and you're on.
For office use, the interesting parts are the microphone and the weight. The noise-cancelling mic is removable, and Creative says it filters out background noise and chatter so your voice comes through clearly — useful in a shared space or a home office where a dishwasher is running somewhere behind you. The in-line remote handles volume and mic mute, and it has a clip on the back so the cable doesn't drag across your desk when you move. At 187 g with plush velvet padding, a retractable headband and rotating ear cups, this is a headset designed to disappear on your head during long sessions. The 40 mm dynamic drivers cover a 20 Hz–20,000 Hz range.
Where it falls short is flexibility. Passive noise cancellation means it blocks sound by physically covering your ears, not by electronics. There's no Bluetooth, so you can't walk to the kitchen mid-call. And it's a wired headset, full stop.
JBL Live 670NC: Who It's For
The JBL Live 670NC is the opposite philosophy: cut the cord and manage the world around you electronically. Two noise-sensing mics drive True Adaptive ANC that adjusts continuously, and Smart Ambient lets surrounding sound back in without you removing the headphones — handy when a colleague walks up to your desk. Four noise-sensing mics in total feed that system, and JBL says your voice stays clear on calls even outdoors in wind.
Battery is the headline number. Up to 65 hours of wireless listening, or 50 hours with Bluetooth and ANC both running, and a 5-minute charge buys 4 more hours. Charge time is 3 hours over USB-C. That's a headset you can reasonably charge once a week and forget about. Bluetooth 5.3 with multipoint pairs to two devices at once, so a call can interrupt your music without you re-pairing anything. Auto play and pause stops audio when you lift the headphones off and resumes when you put them back on. Tap the earcup for Alexa or Google Assistant.
The 40 mm drivers handle 20 Hz–20 kHz with 32 ohm impedance and 98 dB sensitivity, and JBL Spatial Sound converts stereo content into a virtual surround presentation for movies and games. The JBL Headphones app lets you customize ANC behaviour and headphone functions.
Two honest caveats. First, these are on-ear, not over-ear — the cups rest on your ears, which some people find less plush over a full workday than an around-the-ear fit. Second, there is no headphone jack. Everything goes through Bluetooth, so a desktop with no Bluetooth adapter needs one.
Buy it if you want a comfortable wireless headset for office days that also handles commuting, calls and travel. Skip it if you need a wired connection for a console, a mixing desk or a latency-critical setup.
Side-by-Side: Which Should You Choose?
• Best for a fixed office desk → Creative Sound Blaster Blaze. Plug into the 3.5 mm jack and it just works, with no charging routine.
• Best for blocking out an open-plan office → JBL Live 670NC. Adaptive ANC with Smart Ambient is a real active system; the Blaze relies on passive isolation only.
• Best for long-session comfort by weight → Creative Sound Blaze. 187 g with velvet padding, a retractable headband and rotating cups is genuinely light for an over-ear headset.
• Best for wireless multipoint switching → JBL Live 670NC. Bluetooth 5.3 connects two devices at once, so work laptop and phone coexist.
• Best for console or analog gear → Creative Sound Blaster Blaze. PS5, PS4, Xbox, PC, Mac — anything with an analog jack.
• Best for clear voice on calls → both, for different reasons. The Blaze gives you a removable noise-cancelling boom mic; the JBL gives you four noise-sensing mics with wind handling.
• Best low-latency, cable-free option → neither, strictly. The Blaze is wired with zero latency; the JBL compensates with a Video Mode that keeps audio and visuals in sync, but it's still Bluetooth.
For an office-first buyer, I'd go with the JBL Live 670NC. The adaptive noise cancelling, multipoint pairing and that enormous battery life are exactly what a working day asks for: silence when you need to concentrate, your phone and laptop both connected, and a USB-C charge you do on the weekend. In my opinion the Creative Sound Blaster Blaze is the better pick only if your setup is a single wired desk and you never want to think about charging — it's lighter, cheaper to run in effort terms, and its removable boom mic is a genuinely good call tool. But for a headset that follows you through an office day, the JBL wins.
No. It's a wired headset that connects over a 3.5 mm analog jack, so it works with anything that has that port — PC, Mac, PS5, PS4 and Xbox included. There's no Bluetooth and no battery.
Does the JBL Live 670NC have a headphone jack?
No. It's wireless-only over Bluetooth 5.3, with a detachable audio cable listed in the box contents for wired listening where supported, but the spec sheet lists no headphone jack. If your desk lacks Bluetooth, budget for an adapter.
By weight, the Creative Sound Blaster Blaze at 187 g with velvet padding and rotating ear cups is the lighter, plusher over-ear design. The JBL is on-ear, so the cups press on your ears rather than around them — some people love that, others prefer the over-ear fit.
If latency genuinely matters, wired always wins, so the Creative Sound Blaster Blaze is the safer call. The JBL's Video Mode is designed to keep audio and visuals in sync, but it's still a Bluetooth connection.
