If you want a wired gaming headset with a retractable boom mic and a tough aluminum frame, choose Razer Kraken Pro V2; if you need wireless noise cancelling with marathon battery life for commuting, study and travel, choose JBL Live 670NC. Those two sentences are the whole article in miniature — everything below is the reasoning behind them. In my opinion these are two of the best selling headphones in their respective corners of the market, and they sell well for completely opposite reasons.
• Razer Kraken Pro V2 — biggest strength: a purpose-built gaming tool. 50 mm Razer custom tuned drivers, a fully-retractable mic, an in-line remote, and a Bauxite aluminum headband that stays light and flexible over long sessions.
• Razer Kraken Pro V2 — biggest trade-off: it is analog and wired, and it has no noise cancelling at all. You are tethered to your device, and it is not built for wireless listening on the move.
• JBL Live 670NC — biggest strength: freedom and endurance. True Adaptive ANC, Smart Ambient, up to 65 hours of battery, fast charging, multipoint Bluetooth 5.3 and spatial sound in a foldable on-ear design.
• JBL Live 670NC — biggest trade-off: it is an on-ear headphone with a plastic enclosure, and its mic is built for calls, not for a competitive gaming voice channel.
• Who each pick is for: Razer Kraken Pro V2 → PC, PlayStation, Xbox and Switch players who want a headset that just works when plugged in. JBL Live 670NC → commuters, students, remote workers and travellers who want one wireless pair for everything else.
The Kraken Pro V2 is a gaming headset first and a music headphone second, and the spec sheet says so out loud. The 50 mm Razer custom tuned drivers are the headline: that is a large driver for a headset in this class, and Razer has tuned it toward crystal clear highs and rumbling lows — a sound signature aimed at footsteps, gunfire and explosions rather than flat studio accuracy. The frequency range runs 20 Hz to 20,000 Hz, the impedance is 32 ohm and the sensitivity is rated at 118 dB, with a separate 123 dB figure at 1 kHz. In plain terms, that is an easy-to-drive analog headset that gets loud without needing a dedicated amp.
The physical design is where I think it earns its keep. The headband is made of Bauxite aluminum, which keeps it lightweight and extremely flexible — you can bend it and it comes back, which matters if you have ever had a plastic headband crack on you. The oval ear cushions are designed for full-ear coverage, and Razer clearly prioritised long-wearing comfort over portability. The fully-retractable microphone is the feature I would point a buyer to first: it slides into the earcup when you are not talking, so the headset can double as a normal pair of headphones without a boom sticking out of your face. There is an in-line remote for quick control, and the box includes a 1.3 m main cable plus a 2 m mic splitter adapter cable — that splitter is what lets you run it into a PC with separate mic and headphone jacks, and it is also what makes the headset work across PC, PS4, Xbox One, Switch and mobile devices.
Who should buy it: anyone who plays on a console or PC and wants one wired headset that plugs into basically everything. The 3.5 mm jack means no pairing, no charging, no latency. Who should skip it: if you want to walk around the house, take calls on the train, or block out an open-plan office, this is the wrong tool. There is no noise cancelling here — the noise control field literally reads "None" — and no wireless mode worth relying on for daily listening. It is a desk-and-couch headset, and it is very good at being one.
The JBL Live 670NC is the opposite philosophy: it wants to follow you everywhere and never make you think about a charger. Battery is the number that jumps off the sheet — up to 65 hours of wireless listening with Bluetooth on and ANC off, or around 50 hours with both active. When you do run low, a 5-minute fast charge buys roughly 4 more hours. A full charge takes about 3 hours via USB-C. That combination is why I would recommend it to almost anyone whose headphones live in a bag.
The noise cancelling is the second pillar. Two noise-sensing mics power True Adaptive ANC that adjusts in real time — JBL describes four noise-sensing mics in total across the system — and Smart Ambient lets the outside world back in without you taking the headphones off. That is the feature that makes the difference between "I'll just take these off to hear you" and actually keeping them on all day. Bluetooth 5.3 with multipoint means two devices connected at once, so a call can interrupt your laptop audio without a re-pairing ritual, and the 10 m range is standard but entirely adequate.
Sound-wise, the 40 mm dynamic drivers deliver JBL Signature Sound, and JBL Spatial Sound turns stereo content into a virtual surround presentation — useful for movies and games on a phone or laptop. There is a built-in mic, tap-to-activate Alexa or Google Assistant, auto play and pause when you take them off, and the free JBL Headphones app for customising ANC behaviour and switching between Audio Mode and Video Mode for lip-sync. The trade-offs are real, though: this is an on-ear design with a plastic enclosure, weighing 0.42 kg, and on-ear headphones clamp rather than cup your ears — some people love that, some find it fatiguing after a few hours. Sensitivity is rated 98 dB at 32 ohm. And the microphone is there for calls and voice assistants, not for shouting callouts to a squad.
Who should buy it: commuters, students, remote workers, frequent flyers — anyone who wants one pair of wireless headphones for music, calls, video and travel, in a foldable shape that packs down. Who should skip it: competitive gamers who need a boom mic and zero wireless latency, and anyone who strongly prefers the feel of full over-ear cups.
Side-by-Side: Which Should You Choose?
• Best for battery life → JBL Live 670NC. Up to 65 hours with ANC off, roughly 50 with ANC on, plus a 5-minute charge for about 4 hours of playback.
• Best for noise cancelling → JBL Live 670NC. True Adaptive ANC with Smart Ambient. The Kraken Pro V2 has no noise control at all.
• Best for long-session comfort at a desk → Razer Kraken Pro V2. Full-ear oval cushions and a flexible Bauxite aluminum headband built for marathon sessions.
• Best for travel and commuting → JBL Live 670NC. Wireless, foldable, multipoint, voice assistant, auto play/pause — and it packs away.
• Best for wired reliability → Razer Kraken Pro V2. No pairing, no charging, no dropouts; the included splitter cable covers PC, PS4, Xbox One, Switch and mobile.
• Best for calls and meetings → JBL Live 670NC. Built-in mic plus multipoint so work and personal devices stay connected together.
• Best for one pair that does everything → JBL Live 670NC, unless gaming is your primary job for the headphones.
If I had to pick one, I would buy the JBL Live 670NC. In my opinion it covers far more of a normal person's day: wireless freedom, adaptive noise cancelling, spatial sound, multipoint and battery life measured in days rather than hours. It is the pair I would recommend to a friend who asked me for "good headphones" without any other context. The Razer Kraken Pro V2 is the better answer to a narrower question — and if that question is "I play games on a console or PC and want a wired headset that never needs charging," it is the one I would point you to instead. Check the current price on Amazon before you commit, since both sit in different budget brackets depending on the day.
what is the best selling headphones
There is no single model that wins everywhere — it splits by category. Wired gaming headsets like the Razer Kraken Pro V2 and wireless everyday headphones like the JBL Live 670NC both sell strongly because they serve completely different buyers. Judge by your use case, not by a single bestseller label.
what is the best selling headphones of all time
That kind of all-time record belongs to long-running mainstream models from the big audio brands, and it shifts over time. What matters more for you: the Kraken Pro V2 has been a staple wired gaming headset for years, while the Live 670NC is a newer wireless design built around ANC and battery life.
what are the best selling headphones in the world
Globally, the volume leaders are affordable wireless models from mass-market brands, because wireless convenience outsells everything else. Within that group, the JBL Live 670NC competes on adaptive ANC, up to 65 hours of battery and multipoint Bluetooth 5.3; the Kraken Pro V2 competes in the wired gaming niche instead.
what is the most popular brand of headphones
There is no single answer — JBL is one of the most widely recognised audio brands worldwide, and Razer is one of the best-known names in gaming peripherals. Popularity tells you a brand is trusted; it does not tell you which headphone fits your ears, your devices or your commute.
