• Razer BlackShark V2 — biggest strength: THX 7.1 spatial surround sound through 50mm TriForce Titanium drivers, plus a detachable HyperClear Supercardioid mic built for voice isolation.
• Razer BlackShark V2 — biggest trade-off: Battery life tops out at 24 hours, and the wireless 2.4GHz link is aimed at PC, with console play leaning on the 3.5mm jack.
• Amazon Renewed JBL Tune 720BT — biggest strength: Up to 76 hours of playback, a 5-minute speed charge that yields 3 extra hours, and a 220g foldable frame.
• Amazon Renewed JBL Tune 720BT — biggest trade-off: It is a renewed unit with a 90-day limited warranty, no headphone jack, and no boom mic for team chat.
• Buy the Razer if gaming audio, mic clarity and sound isolation are your priorities.
• Buy the JBL if you want all-day wireless listening, long battery life and portability for music and calls.
The BlackShark V2 Pro is, first and last, a gaming headset. Razer built it around THX 7.1 Surround Sound, which is designed to place audio cues more precisely than standard 7.1 processing — footsteps, reloads and directional shots land where they should. The 50mm TriForce Titanium drivers are split into three parts so highs, mids and lows get tuned individually, which is why the frequency range stretches from 12 Hz to 28 kHz. That is a wider spread than most everyday headphones offer, and it points to a headset tuned for detail and rumble in equal measure.
Comfort and isolation get real attention here too. The over-ear cushions use soft, breathable memory foam to cut heat and pressure on long sessions, and the closed earcups are explicitly designed to shut noise out. If you play in a shared room or next to a noisy PC, that isolation matters more than any spec sheet number. The detachable HyperClear Supercardioid mic is a 9.9mm unit with better voice isolation and a truer reproduction of your speech, tunable through Razer Synapse — a clear nod to streamers and squad players.
Amazon Renewed JBL Tune 720BT: Who It's For
The JBL Tune 720BT is the opposite philosophy: light, simple, and built to disappear on your head. At 220 grams it is one of the lighter over-ear designs you will find, and the foldable frame makes it easy to toss in a backpack. Bluetooth 5.3 handles the wireless connection to your phone, and there is no cable jack at all — this is a purely wireless pair.
Battery is the headline. JBL rates it at up to 76 hours of playback with a 2-hour charge over USB-C, and a quick 5-minute top-up delivers 3 more hours. For commuters, travelers and anyone who resents charging cables, that is a genuinely different category of convenience. The sound is JBL Pure Bass, with a 20 Hz to 20,000 Hz range, and you can reshape it through the free JBL Headphones App EQ with voice prompts in your chosen language.
Calls are handled by on-ear buttons with Voice Aware, which lets you hear your own voice while talking — handy for meetings and quick phone calls. The trade-offs are real, though. There is no boom mic, so voice isolation will not match a gaming headset. Noise control is sound isolation only, not active cancellation. And because this listing is Amazon Renewed, the unit is pre-owned and inspected rather than new, backed by a 90-day limited warranty instead of a multi-year one. Buy it if you want long-battery, lightweight wireless listening for music, podcasts and calls. Skip it if you need a mic for competitive chat or you prefer the peace of mind of a new-product warranty.
Side-by-Side: Which Should You Choose?
• Best for gaming audio and spatial positioning → Razer BlackShark V2 (THX 7.1, 50mm TriForce drivers).
• Best for battery life → Amazon Renewed JBL Tune 720BT (up to 76 hours vs up to 24 hours).
• Best for commuting and travel → Amazon Renewed JBL Tune 720BT (220g, foldable, no cables).
• Best for PC and console flexibility → Razer BlackShark V2 (2.4GHz wireless for PC, 3.5mm jack for PS5, PS4 and Switch).
• Best for phone-first listening and EQ tweaking → Amazon Renewed JBL Tune 720BT (Bluetooth 5.3, JBL Headphones App).
• Best for sound isolation in a noisy room → Razer BlackShark V2 (closed earcups, memory foam cushions).
• Best warranty coverage → Razer BlackShark V2 (2-year manufacturer vs 90-day limited on the renewed JBL).
• Best for marathon listening without charging anxiety → Amazon Renewed JBL Tune 720BT (5-minute charge = 3 hours).
In my opinion, the Razer BlackShark V2 Pro is the stronger pick for anyone whose main use is gaming on a PC. The spatial audio, the swappable boom mic and the closed-back isolation are things the JBL simply does not attempt, and the two-year warranty backs it up. That said, I would steer most casual listeners toward the Amazon Renewed JBL Tune 720BT: 76 hours of battery, 220 grams and a foldable build make it a far better everyday companion, provided you are comfortable with a renewed unit and a shorter 90-day warranty. Pick based on whether you game or you listen.
what is the best selling headphones
There is no single answer, and I will not quote sales figures — that data is not part of this comparison. What I can say is that the two designs here sell well for different reasons: gaming headsets like the Razer BlackShark V2 win on mic quality and spatial audio, while lightweight Bluetooth models like the JBL Tune 720BT win on battery life and portability. In my opinion, "best selling" usually just means "fits the most common use case," and for most people that is casual wireless listening.
what is the best selling headphones of all time
I cannot cite historical sales numbers, and no spec sheet tells you that. What I can compare is what each design offers. The JBL Tune 720BT leans on the kind of formula that tends to move units: long battery life, a light foldable frame and a well-known bass-forward sound. The Razer BlackShark V2 targets a narrower audience — PC and console gamers who need a detachable boom mic and THX 7.1 spatial audio. Different crowds, different reasons to buy.
what are the best selling headphones in the world
Rather than guess at global sales, look at the features buyers actually reward. The JBL Tune 720BT covers Bluetooth 5.3, up to 76 hours of playback, speed charge and app-based EQ — a checklist built for mass appeal. The Razer BlackShark V2 answers a specific need with 2.4GHz low-latency wireless, 50mm drivers and a 9.9mm detachable mic. In my opinion, mainstream buyers lean toward the lighter, longer-lasting wireless pair, while gamers lean Razer.
what is the most popular brand of headphones
Popularity shifts by category, so I will not crown a brand. Razer is a gaming-first name, and this headset reflects that with THX 7.1, a HyperClear Supercardioid mic and a 2.4GHz connection. JBL is a general-listening name, and the Tune 720BT reflects that with Pure Bass sound, app EQ and a 76-hour battery. If your priority is gaming chat and immersion, Razer fits better; if it is all-day wireless music, JBL fits better.
