• Amazon Renewed Razer Opus Active — biggest strength: THX-certified dynamic drivers, advanced active noise cancellation and up to 40 hours of playback in a comfortable over-ear design.
• Amazon Renewed Razer Opus Active — biggest trade-off: It is a renewed unit with a 90-day limited warranty, and its push-button controls are aimed at listeners, not at people who live on calls.
• Jabra Engage 65 — biggest strength: DECT wireless with a range up to 150 m/490 ft, an advanced noise-cancelling microphone, an integrated busylight and a 2-year manufacturer warranty.
• Jabra Engage 65 — biggest trade-off: It is built for voice, not for immersive listening, and the dual-ear on-ear fit is a very different comfort story from plush over-ear cushions.
• Who each pick is for: Razer Opus Active for travellers, commuters and media watchers; Jabra Engage 65 for office workers, remote agents and call-center staff.
The Opus Active is, at heart, a consumer listening headphone. Razer tuned it with THX to deliver what the spec sheet calls a rich, balanced sound stage, and the 20 Hz – 20,000 Hz dynamic drivers cover the full range you'd expect from a media-first pair. Advanced ANC detects and nullifies incoming noise, which is exactly the feature you want on a noisy train, a plane, or a shared open-plan space where you're trying to watch something rather than talk to anyone.
Comfort is clearly a design priority. Plush leatherette memory-foam ear cushions, a well-balanced weight (9.76 ounces) and a snug clamping force are meant to keep it on your head through long commutes. Battery life is rated up to 40 hours, Bluetooth 5.0 handles the wireless side, and there's a 3.5 mm jack for wired listening when you want it. Auto play/auto pause and a carrying case round out the everyday package, and Quick Attention Mode — a press of the power button that amplifies ambient sound — is genuinely useful when you're crossing a road or ordering a coffee without taking the headphones off.
Who should buy it: anyone who wants one headphone for music, films, podcasts and travel, and who is comfortable buying a renewed unit. Who should skip it: if your day is built around business calls, if you need a boom microphone that isolates your voice, or if you want a long manufacturer warranty rather than the 90-day limited warranty that comes with a renewed product. In my opinion, this is the pick for the person whose priority is listening, not talking.
The Engage 65 SE is a professional communications tool and makes no apology for it. Its headline number is range: DECT wireless keeps you connected up to 150 meters / 490 feet from the base, which Jabra frames as supporting up to three times more users in the same office space without losing connection quality. If you've ever paced a hallway mid-call on a Bluetooth headset and had the audio stutter, that's the problem this design exists to solve.
The audio chain is pointed squarely at voice. An advanced noise-cancelling microphone and enhanced speakers are meant to keep calls clear even in a noisy office, and the headset is stated to meet Skype for Business Open Office requirements. There's an integrated busylight that acts as a do-not-disturb sign for colleagues, a genuinely clever touch if you work in a room full of people who can't tell when you're on a call. It can connect to two devices at once — desk phone and softphone — so you're not re-pairing every time you switch.
Battery is quoted at up to 13 hours of talk time with a 90-minute charge, and the spec sheet also lists a 52-hour figure tied to the carrying case, so there's a charging-station workflow built in. The box includes the headset, charging station, power supply, USB cable and user manual. The dual-ear model is on-ear with faux leather, polycarbonate and stainless steel construction, and it carries a 2-year manufacturer warranty.
Who should buy it: people who spend their working hours on calls — support agents, sales teams, reception, remote workers who live in softphone apps. Who should skip it: anyone shopping primarily for music, films or gaming immersion, and anyone who dislikes on-ear pressure or wants a compact travel headphone.
Side-by-Side: Which Should You Choose?
• Best for music and movies → Amazon Renewed Razer Opus Active. THX tuning, ANC and 40 hours of playback are built for media, not meetings.
• Best for wireless range → Jabra Engage 65. Up to 150 m / 490 ft on DECT versus the typical room-scale reach of Bluetooth 5.0.
• Best for battery life → Amazon Renewed Razer Opus Active on raw playback (up to 40 hours), though Jabra quotes up to 52 hours with its carrying case and 13 hours of talk time. They measure different things: listening versus talking.
• Best for comfort over long sessions → Amazon Renewed Razer Opus Active. Over-ear leatherette memory-foam cushions and a balanced 9.76-ounce build are aimed at extended wear.
• Best for warranty peace of mind → Jabra Engage 65. A 2-year manufacturer warranty versus a 90-day limited warranty on the renewed Razer.
• Best for shared or open-plan offices → Jabra Engage 65. The busylight and open-office call performance are designed for exactly that environment.
• Best for travel → Amazon Renewed Razer Opus Active. A carrying case, a 3.5 mm jack and ANC make it the more portable, more versatile companion.
• Best for switching between desk phone and softphone → Jabra Engage 65. Two simultaneous connections, no re-pairing.
• Best for awareness of your surroundings → Amazon Renewed Razer Opus Active. Quick Attention Mode amplifies ambient sound on demand.
In my opinion, these two barely compete — they solve different problems, and the "best selling" framing only makes sense once you decide which problem is yours. If I were buying for myself as a general listener, traveller or movie watcher, I'd take the Amazon Renewed Razer Opus Active: THX-tuned sound, ANC, 40 hours of battery and a comfortable over-ear fit are a lot of headphone for one device. If my income depended on being clearly heard on calls all day, I'd take the Jabra Engage 65 without hesitation — the DECT range, noise-cancelling mic, busylight and 2-year warranty are built for that job. Buy for the job you actually do. And check the current price on Amazon before you commit, since renewed and new stock move around.
FAQ
what is the best selling headphones
what is the best selling headphones of all time
No data sheet here can answer that, and I won't invent a figure. What I can tell you is that the two products on this page sit in different markets: one is a renewed consumer headphone with THX audio and 40-hour battery, the other a DECT office headset with a 150 m range and a noise-cancelling mic. Historical sales leaders tend to come from whichever category has the largest buyer pool at the time.
what are the best selling headphones in the world
Again, that's a global sales question rather than a spec question, so I'll stick to what's verifiable. The Razer Opus Active targets media lovers with ANC, Bluetooth 5.0 and a 3.5 mm wired option. The Jabra Engage 65 targets offices with dual-device connectivity, a busylight and a 2-year warranty. Both are strong within their own niche rather than across all headphones.
what is the most popular brand of headphones
Popularity varies by category and region, so I won't claim a winner. Razer is a well-known name in gaming and consumer audio, and the Opus Active carries THX certification and a 40-hour battery. Jabra is a well-known name in business communications, and the Engage 65 offers 150 m DECT range and all-day talk time. If brand popularity matters to you, weigh it against the features you actually need.
