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 gaming headset with a retractable boom mic and a lightweight aluminum frame, choose Razer Kraken Pro V2; if you need long wireless listening with massive battery life and a foldable travel-friendly build, choose Amazon Renewed JBL Tune 720BT.
• Razer Kraken Pro V2 — biggest strength: 50 mm custom-tuned drivers, a fully retractable boom mic, and a Bauxite aluminum headband built for long gaming sessions.
• Razer Kraken Pro V2 — biggest trade-off: It's a wired analog headset with no active noise cancellation, and at 340 g it's noticeably heavier than the JBL.
• Amazon Renewed JBL Tune 720BT — biggest strength: Up to 76 hours of battery life, Bluetooth 5.3, USB-C speed charge, and a foldable 220 g design.
• Amazon Renewed JBL Tune 720BT — biggest trade-off: It's a renewed unit with a 90-day limited warranty, no wired jack at all, and a mic that lives on the ear cup rather than a boom arm.
• Who each is for: The Kraken Pro V2 is for gamers who want clear voice chat and a cable they can trust; the JBL Tune 720BT is for commuters, students, and remote workers who want one charge to last a week.
The Kraken Pro V2 is a purpose-built gaming headset, and its spec sheet reads that way. The 50 mm Razer custom-tuned dynamic drivers cover a 20 Hz to 20,000 Hz range with 32 ohm impedance and 118 dB sensitivity, which in plain terms means they're easy to drive from a controller, a phone, or a motherboard jack without any amp. Razer's own framing is "crystal clear highs and rumbling lows," and the tuning is aimed at putting you inside the action rather than delivering a flat studio response.
The feature that matters most for multiplayer is the fully retractable microphone with an in-line remote. You pull the mic out when you're talking to your squad, push it back into the ear cup when you're not, and control volume and mute from the cable. That's a genuinely different experience from a mic that permanently sticks out or one that lives on the ear cup. The connection is a 3.5 mm jack, and the box includes a 1.3 m cable plus a 2 m mic splitter adapter cable — that splitter is what lets you separate headphone and mic signals for PC setups that need it. Razer lists compatibility with PC, PS4, Xbox One, Switch, and mobile devices.
Who should buy it: gamers on PC or console who want a reliable wired connection, a boom mic they can stow, and a headset that survives being tossed in a bag. Who should skip it: anyone who wants wireless freedom, active noise cancellation, or a headset light enough to forget they're wearing. There's no noise control here at all, and no Bluetooth audio for your phone beyond the wired jack. If you mostly listen to music on the move, this isn't the tool.
Amazon Renewed JBL Tune 720BT: Who It's For
The JBL Tune 720BT is the opposite philosophy: wireless first, convenience above all. Bluetooth 5.3 handles the connection, and there's no headphone jack anywhere on it — so this is a headphones-only, cable-free device by design. The headline number is battery life: up to 76 hours on a charge, with a 2-hour full recharge over USB-C and a speed-charge feature that gives you roughly 3 extra hours from a 5-minute top-up. That combination is the real story. A 5-minute charge before you walk out the door covering a commute is the kind of detail that changes how you actually use a headphone.
Sound-wise, JBL leans on its Pure Bass tuning, the same family of sound signature the brand uses across its line. The dynamic drivers cover 20 Hz to 20,000 Hz. If you want to adjust that signature, the free JBL Headphones App lets you tailor the EQ and gives you voice prompts in your chosen language — a nice touch if you don't want to memorize button combinations. Controls are handled through touch and voice on the ear cup, and JBL lists sound isolation as the noise approach, meaning it passively blocks some outside noise rather than actively cancelling it.
The design is built for portability. At 220 g it's significantly lighter than the Kraken Pro V2, and the foldable hinge means it collapses down for a bag or a seat pocket. The enclosure is plastic with thermoplastic elastomer (TPE) accents in blue. For calls, there's Voice Aware, which lets you hear your own voice while you're talking so you don't shout — a small feature that makes a real difference on long conference calls. Buttons on the ear cup handle playback and call management.
Who should buy it: commuters, students, and remote workers who want one pair of over-ears for music, calls, and video, and who hate charging things. Who should skip it: competitive gamers who need a boom mic positioned at their mouth, and anyone who wants a wired fallback. There is no jack, so if the battery dies and you have no cable option, you're done listening. Also worth understanding: this is a renewed unit, which means it's a previously owned product that's been inspected and repackaged, backed by a 90-day limited warranty rather than a full-length new-product warranty.
• Best for battery life → Amazon Renewed JBL Tune 720BT. Up to 76 hours is in a different league from any wired headset, because the Kraken Pro V2 doesn't have a battery at all.
• Best for voice chat and gaming → Razer Kraken Pro V2. The retractable boom mic and in-line remote are built for team communication in a way an ear-cup mic isn't.
• Best for long-session comfort → Amazon Renewed JBL Tune 720BT. 220 g versus 340 g is a meaningful difference on hour six.
• Best for durability of the frame → Razer Kraken Pro V2. Bauxite aluminum headband with flexibility built in, versus a plastic and TPE enclosure.
• Best for travel and portability → Amazon Renewed JBL Tune 720BT. Foldable, light, and no cable to untangle.
• Best for plug-and-play with no charging → Razer Kraken Pro V2. The 3.5 mm jack plus the included splitter cable means it works the moment you plug it in.
• Best for tuning your own sound → Amazon Renewed JBL Tune 720BT. The JBL Headphones App EQ lets you shape the signature; the Kraken has no app or EQ.
• Best for warranty peace of mind → Razer Kraken Pro V2. A 1-year warranty versus a 90-day limited warranty on the renewed JBL.
• Best for multi-device wired flexibility → Razer Kraken Pro V2. PC, PS4, Xbox One, Switch, and mobile all connect over the same analog jack.
In my opinion, if you're buying one headset for gaming and voice chat, I'd take the Razer Kraken Pro V2. The retractable boom mic, the aluminum headband, the 50 mm drivers, and the 1-year warranty make it the more dependable single-purpose tool, and it never needs charging. I'd only steer you to the Amazon Renewed JBL Tune 720BT if wireless freedom and battery life are your top two priorities — for commuting, study, and calls, up to 76 hours with a 5-minute speed charge is genuinely hard to argue with. Just go in knowing it's a renewed unit with a 90-day warranty and no wired fallback. Before you decide, check the current price on Amazon for both, since that's the one variable that can flip this call.
FAQ
Up to 76 hours of wireless listening per charge, with a full recharge in about 2 hours over USB-C. A 5-minute quick charge adds roughly 3 hours, which covers a short commute or a workout.
Yes. It has hands-free calling with Voice Aware, which lets you hear your own voice while you talk, and call controls are on the ear cup. It's a built-in mic rather than a boom arm, so it's better for calls than for competitive team chat.
It's a previously owned product that has been inspected and repackaged for resale, and it carries a 90-day limited warranty rather than the full warranty you'd get on a new unit. That shorter coverage is the main thing to weigh against the wireless and battery advantages.
