How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a headset built for gaming immersion with spatial audio and a detachable boom mic, choose Amazon Renewed Razer BlackShark V2; if you need active noise cancelling for music, travel and calls with far longer battery life, choose Sony WH-CH720N. These two look similar on a shelf — both over-ear, both wireless — but they are aimed at completely different listeners.
• Amazon Renewed Razer BlackShark V2 — biggest strength: THX 7.1 spatial surround and 50mm Triforce Titanium drivers built specifically for pinpointing in-game audio, plus a detachable cardioid mic.
• Amazon Renewed Razer BlackShark V2 — biggest trade-off: It is a renewed unit with a 90-day limited warranty, no wired jack, and just 24 hours of battery life.
• Sony WH-CH720N — biggest strength: Active Noise Cancellation with up to 35 hours of battery and a 10-minute quick charge for an hour of playback.
• Sony WH-CH720N — biggest trade-off: No boom mic and no spatial gaming tuning — its drivers are tuned for balanced music, not footstep detection.
• Who each is for: Gamers who want positional audio and a proper mic → Amazon Renewed Razer BlackShark V2. Commuters, students and office listeners who want quiet and endurance → Sony WH-CH720N.
This is a gaming headset first and everything else second. The headline feature is THX 7.1 Surround Sound, which is designed to feed you spatial audio cues that go beyond ordinary directional stereo. In practice, that is the kind of thing that matters when you are trying to place a footstep behind you or a reload to your left. The 50mm Triforce Titanium drivers are split into three tuned parts for highs, mids and lows, and the frequency range runs from 12 Hz to 28 kHz — a wide spread that gives low-end rumble room to breathe without smothering voices.
Comfort gets real attention too. The ear cushions are oval and infused with cooling gel, which is a deliberate choice to stop heat and pressure building up during long sessions. The headset weighs 320 g, so it is not featherweight, but the memory foam padding is there to spread that load. The detachable Razer Hyperclear Cardioid mic is tuned for focused voice pickup and can be fine-tuned through Razer Synapse 3, and the whole thing connects over Bluetooth 5.2 with media controls on the headset.
Who should buy it: PC, Mac, PS4, PS5 and Switch players who want a single headset for voice chat and positional audio, and who are comfortable buying renewed. Who should skip it: anyone who wants active noise cancelling, anyone who needs a wired option, and anyone who wants a brand-new sealed unit. This is a renewed product that has been inspected and tested to work and look like new, backed by a 90-day limited warranty and the Amazon Renewed Guarantee for replacement or refund. There is no headphone jack here — it is Bluetooth only.
The Sony WH-CH720N is a lifestyle headphone. Its core pitch is active noise cancellation paired with endurance: up to 35 hours of playback with noise cancelling on, and a quick charge that gives you roughly 60 minutes of listening from a 10-minute top-up. That combination is what makes it a genuinely practical daily driver — you charge it rarely, and when you forget, a short plug-in rescues your commute.
Sound is handled by an Integrated Processor V1 and DSEE, with the goal of natural vocals and balanced tuning. You can adjust the sound to taste through the EQ in the Sony Headphones Connect app, and it is 360 Reality Audio certified, which analyses your ear shape in the app for a more personalised spatial mix. For calls, Precise Voice Pickup Technology, a wind noise reduction structure and beamforming mics work together to keep your voice clear and cut down background noise.
Comfort is a design priority — a lightweight, ergonomic build that is meant to stay easy on the head for the full 35 hours. It supports Multipoint Connection so you can stay paired to two devices at once, plus Swift Pair and Fast Pair for quick setup, easy button operation and voice control. Bluetooth range is listed at 10 metres, and unlike the Razer it does include a stereo mini jack for wired listening. Colour here is blue.
Who should buy it: commuters, remote workers, students and frequent flyers who want quiet, long battery and clear calls. Who should skip it: competitive gamers who need a boom mic and low-latency positional cues — the Sony's strength is quiet listening, not game audio.
Side-by-Side: Which Should You Choose?
• Best for gaming audio → Amazon Renewed Razer BlackShark V2. THX 7.1 spatial surround and 50mm Triforce Titanium drivers exist for in-game positioning.
• Best for battery life → Sony WH-CH720N. 35 hours versus 24 hours on the Razer.
• Best for voice chat and streaming → Amazon Renewed Razer BlackShark V2. The detachable Hyperclear Cardioid mic is purpose-built for focused voice pickup.
• Best for calls on the move → Sony WH-CH720N. Beamforming mics, Precise Voice Pickup and a wind noise reduction structure are tuned for conversation.
• Best for wired listening → Sony WH-CH720N. It has a stereo mini jack; the Razer has no jack at all.
• Best for multi-device switching → Sony WH-CH720N. Multipoint Connection keeps two devices paired at once.
• Best for buying new vs renewed → Sony WH-CH720N. If a sealed retail unit matters to you, the Razer is a renewed product with a 90-day limited warranty.
If I had to pick one, I would buy the Sony WH-CH720N. In my opinion it covers more of everyday life: active noise cancelling, 35 hours of battery, a quick charge that rescues a forgotten charge, multipoint pairing and a wired fallback. The Amazon Renewed Razer BlackShark V2 is the better tool if gaming is your main job — but it is a specialist, and the renewed status plus the 24-hour battery and missing jack make it a narrower buy. For most people reading this, the Sony is the safer everyday headphone.
what is the best selling headphones
There is no single best-selling headphone — it depends on the category. Gaming headsets like the Razer BlackShark line compete in a different market from lifestyle noise-cancelling models like the Sony WH-CH720N, so the "best seller" in gaming is rarely the best seller in travel or commuting. Match the category to your use before chasing a popularity label.
what is the best selling headphones of all time
No data sheet here claims any all-time sales record, and I would not trust a blanket claim either. What you can compare is design intent: the Razer is built for in-game spatial audio with a detachable mic, while the Sony is built for noise cancelling and long battery. Longevity in the market tends to follow whichever category a buyer actually needs.
what are the best selling headphones in the world
Popularity varies by region and by category. In gaming circles, over-ear headsets with boom mics and surround processing dominate; in commuting and office use, active noise cancelling over-ears dominate. The Razer BlackShark V2 fits the first group, the Sony WH-CH720N the second. Your own listening habits matter more than any global label.
what is the most popular brand of headphones
Different brands lead different segments. Razer is a gaming-first brand — its BlackShark V2 is a video-game-themed headset with THX 7.1 and a Hyperclear mic. Sony is a broader consumer audio brand, and the WH-CH720N reflects that with active noise cancelling, DSEE processing and 360 Reality Audio. Neither brand is "the" most popular everywhere; each is strongest in its own lane.
