How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wireless gaming headset built for spatial in-game audio and long sessions at your desk, choose Amazon Renewed Razer BlackShark V2; if you need all-day noise cancelling for commuting, calls and travel with huge battery life, choose JBL Tune 680NC.
• Amazon Renewed Razer BlackShark V2 — biggest strength: THX 7.1 spatial surround and 50mm Triforce Titanium drivers, plus cooling gel-infused oval cushions for marathon gaming sessions.
• Amazon Renewed Razer BlackShark V2 — biggest trade-off: It's a renewed unit with a 90-day limited warranty, and at roughly 320 g it's the heavier of the two on your head.
• JBL Tune 680NC — biggest strength: Adaptive Noise Cancelling with Smart Ambient and up to 76 hours of battery life (up to 50 with ANC on), plus Bluetooth 6.0 multi-point.
• JBL Tune 680NC — biggest trade-off: On-ear cups and a 3.5mm cable are in the box, but there's no charging cable included, and it's tuned for everyday listening rather than competitive gaming cues.
• Who each pick is for: Choose the Razer if you game on PC or console and want immersive positional audio; choose the JBL if you want noise cancelling, calls and battery life for work, travel and commuting.
The BlackShark V2 (Renewed) is a gaming-first headset, and everything about its spec sheet points that way. It's built around THX 7.1 Surround Sound, which the design intends to deliver directional audio cues beyond standard 7.1 — the kind of positional information that helps you place footsteps, gunfire or a teammate's voice in a three-dimensional space. The 50mm Triforce Titanium drivers are split into three parts for individual tuning of highs, mids and lows, which is a deliberate choice for separating the sharp, detail-heavy sounds games throw at you from the low-end rumble of explosions.
Comfort is a real consideration here. Razer uses oval, cooling gel-infused cushions to reduce heat buildup and pressure over long sessions, and the memory foam enclosure is wrapped in a black finish that matches the gaming aesthetic. It's a wireless headset using Bluetooth 5.2, and the detachable Hyperclear Cardioid mic is tuned for focused voice pickup, with further tweaking available through Razer Synapse 3. Battery life is rated at up to 24 hours, which covers a full day of play before you need to recharge.
The detachable mic matters more than it looks: you can pull it off for solo listening and keep the headset purely for audio. That said, this is the model for people who game on PC, Mac, PS4, PS5 or Switch and care about spatial accuracy. If you mostly want to block out office chatter or airplane noise, or you need two-device switching all day, this isn't the headset that's designed for it. And because it's an Amazon Renewed unit — professionally inspected and tested to work and look like new, backed by a 90-day limited warranty and eligible for replacement or refund under the Amazon Renewed Guarantee — you should be comfortable buying refurbished rather than new. If you want the newest retail box and a longer warranty, weigh that carefully.
The JBL Tune 680NC is a different animal entirely: an everyday, on-ear noise cancelling headphone for people who move through their day. Its headline feature is Adaptive Noise Cancelling with Smart Ambient — the cancellation adjusts automatically to what's around you, and Ambient Aware and TalkThru let you hear your surroundings or hold a conversation without pulling the headphones off. All of it is managed through the JBL Headphones app.
Battery life is the spec that jumps off the sheet: up to 76 hours with ANC off and Bluetooth on, or up to 50 hours with ANC on. A 5-minute speed charge adds another 5 hours, and a full recharge takes about two hours. For a commuter or a remote worker, that means charging becomes a weekly chore rather than a nightly one.
Sound is handled by custom 32mm drivers with JBL Pure Bass Sound and JBL Spatial Sound, and there's Hi-Res audio support via the included USB-C to 3.5mm audio cable — useful when you want a wired, higher-detail listen. Calls get two beamforming mics with noise reduction, aimed at keeping your voice clear in busy places. Connectivity is Bluetooth 6.0 with multi-point, so you can pair a laptop and a phone and hop between them, with lower latency for video. The light, foldable on-ear design with a padded headband is made to be carried.
Two things to plan around. First, the headphones are on-ear, not over-ear, which some people find less isolating over long stretches than a full over-ear cup. Second, no charging cable is included — you'll supply your own USB-C cable. And while the adaptive ANC is built for commuting and focus work, this isn't a gaming headset with positional audio cues; it's for music, podcasts, calls and travel.
• Best for gaming and positional audio → Amazon Renewed Razer BlackShark V2. THX 7.1 spatial surround and 50mm Triforce drivers are designed for in-game immersion.
• Best for battery life → JBL Tune 680NC. Up to 76 hours with ANC off, up to 50 with it on, plus a 5-minute speed charge for 5 more hours.
• Best for noise cancelling → JBL Tune 680NC. Adaptive Noise Cancelling with Smart Ambient is the core of the design; the Razer relies on passive sound isolation.
• Best for calls on the move → JBL Tune 680NC. Two beamforming mics with noise reduction versus the Razer's detachable Hyperclear Cardioid mic tuned for focused voice pickup at a desk.
• Best for long desk sessions → Amazon Renewed Razer BlackShark V2. Cooling gel-infused oval cushions are made to prevent heat and pressure buildup.
• Best for carrying around → JBL Tune 680NC. Lightweight, foldable, and built to slip into a bag; the Razer is a heavier over-ear at around 320 g.
• Best for wired listening → JBL Tune 680NC. It has a 3.5mm jack and includes a USB-C to 3.5mm cable; the Razer is wireless-only with no headphone jack.
• Best for a two-device workflow → JBL Tune 680NC. Bluetooth 6.0 multi-point lets you switch between a laptop and a phone seamlessly.
• Best if you're fine with renewed hardware → Amazon Renewed Razer BlackShark V2. It's inspected and tested to work and look like new, with a 90-day limited warranty.
In my opinion, these two barely compete for the same buyer, and that's the point. If your priority is immersive gaming audio, spatial cues and long-session comfort, I'd buy the Amazon Renewed Razer BlackShark V2 — the THX 7.1 processing, 50mm Triforce drivers and gel-infused cushions are all aimed squarely at that job, and the renewed route gets you there if you're comfortable with refurbished hardware. If your day is commuting, calls, focus work and travel, I'd buy the JBL Tune 680NC instead — adaptive noise cancelling, multi-point Bluetooth 6.0 and that enormous battery life are exactly what that life needs. Pick by what you actually do most, not by which spec sheet looks longer.
FAQ
Yes — it has a 3.5mm jack and ships with a USB-C to 3.5mm audio cable, so you can listen wired for Hi-Res audio. Note that JBL doesn't include a charging cable in the box, so you'll need your own USB-C cable.
The JBL Tune 680NC, clearly. It has Adaptive Noise Cancelling with Smart Ambient built in, while the Razer BlackShark V2 relies on passive sound isolation from its over-ear cushions rather than active cancellation.
Yes — it has a detachable Hyperclear Cardioid mic tuned for focused voice pickup, tweakable via Razer Synapse 3. But it's wireless-only with no 3.5mm jack and no multi-point switching, so if you juggle a laptop and phone all day, the JBL is the more practical pick.
