How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the lowest-risk way to get JBL's signature bass tuning with a massive 76-hour battery and a foldable, lightweight build, choose Amazon Renewed JBL Tune 720BT; if you need adaptive noise cancelling, spatial audio and wired Hi-Res listening, choose JBL Tune 780NC.
• Amazon Renewed JBL Tune 720BT — biggest strength: Up to 76 hours of playback with Bluetooth 5.3, a 220 g foldable body, and a 5-minute speed charge that adds about 3 hours.
• Amazon Renewed JBL Tune 720BT — biggest trade-off: No active noise cancelling and no wired jack — it isolates sound passively and streams wirelessly only.
• JBL Tune 780NC — biggest strength: Adaptive Noise Cancelling, JBL Spatial Sound, Hi-Res audio over the bundled USB-C to 3.5 mm cable, and two beamforming mics for calls.
• JBL Tune 780NC — biggest trade-off: Battery drops to about 50 hours with ANC on, the charging cable isn't included, and it costs more as a new retail unit.
• Who each pick is for: The Renewed 720BT suits budget-minded listeners who want long battery and simple controls; the 780NC suits commuters and call-heavy workers who want quiet and detail.
This is the sensible, no-drama option. You get JBL Pure Bass sound, Bluetooth 5.3, and a battery rating of up to 76 hours — a number that matters if you're the type who charges headphones once a week and forgets about it. The 5-minute speed charge giving roughly 3 extra hours is the kind of feature you only appreciate when you're walking out the door with a dead pair.
The physical design is built around portability. At 220 g with a foldable frame and plastic/TPE materials, it's meant to be tossed in a bag without a second thought. Controls live on the ear cup, and the JBL Headphones App adds EQ tweaking plus voice prompts. There's also Voice Aware, which lets you hear your own voice during calls — genuinely useful if you take meetings and hate that muffled "talking underwater" feeling.
JBL Tune 780NC: Who It's For
This is the feature-packed sibling. Adaptive Noise Cancelling adjusts to your surroundings automatically, which is the difference between "the engine noise is slightly less annoying" and "the engine noise is basically gone." Smart Ambient and TalkThru let you hear announcements or hold a quick conversation without pulling the headphones off — a small thing that becomes a big thing on a daily commute.
Audio is where the 780NC separates itself. Custom 40mm dynamic drivers with 32 ohm impedance, plus JBL Spatial Sound for a more enveloping presentation. If you plug in the included USB-C to 3.5 mm cable, you unlock Hi-Res audio for more detail and clarity. That wired path also solves latency for video editing or gaming.
Call quality is a clear step up: two beamforming mics with noise reduction filter out background sound, so a teleconference in a busy café or a call on a train platform sounds far cleaner. Battery is rated up to 76 hours with ANC off, dropping to about 50 hours with it on, and the 5-minute speed charge adds roughly 5 hours. It's 225.2 g, folds flat, and pairs with two Bluetooth devices for quick switching. You get a 1-year manufacturer warranty — but note the charging cable is not included, so budget for a USB-C cable if you don't have one.
Who should buy it: commuters, remote workers, frequent flyers, and anyone who wants ANC, spatial audio and a wired Hi-Res path in one pair. Who should skip it: shoppers who want the absolute simplest, most affordable route and don't care about noise cancelling.
• Best for battery life → Amazon Renewed JBL Tune 720BT. Both are rated at 76 hours, but the 720BT keeps that full figure with wireless listening, while the 780NC drops to roughly 50 hours once ANC is on.
• Best for noise cancellation → JBL Tune 780NC. Adaptive Noise Cancelling plus Smart Ambient is the headline feature the 720BT simply doesn't have.
• Best for calls → JBL Tune 780NC. Two beamforming mics with noise reduction beat the 720BT's Voice Aware approach for crowded environments.
• Best for wired or Hi-Res listening → JBL Tune 780NC. It has a 3.5 mm jack and ships with a USB-C to 3.5 mm cable; the 720BT has no jack at all.
• Best for travel weight and folding → a tie, leaning 720BT. At 220 g versus 225.2 g, both fold, but the 720BT is marginally lighter and simpler.
• Best for app-based tuning → a tie. Both pair with the JBL Headphones App for EQ and control.
• Best for value-minded, low-risk buying → Amazon Renewed JBL Tune 720BT. A Renewed unit with a 90-day limited warranty gets you core JBL sound for less.
• Best for maximum features out of the box → JBL Tune 780NC, with its 1-year manufacturer warranty and richer spec sheet.
If I were buying for myself and my budget allowed it, I'd take the JBL Tune 780NC. Adaptive noise cancelling, spatial sound, Hi-Res wired playback and proper beamforming mics make it the more complete headphone for commuting and working — and 50 hours with ANC on is still excellent. That said, I'd genuinely recommend the Amazon Renewed JBL Tune 720BT to anyone who wants the essentials: big bass, huge battery and a light foldable frame, without paying for features they'll never touch. Buy the 780NC if you want the full experience; buy the Renewed 720BT if you want the smart, economical pick.
what is the best selling headphones
There's no single definitive answer, since "best selling" depends on the category and the retailer. What I can tell you from the specs here is that both the JBL Tune 720BT and JBL Tune 780NC sit in the popular over-ear wireless segment, sharing JBL Pure Bass sound and a 76-hour battery rating — the features that tend to drive demand in this class.

what are the best selling headphones in the world
No list is universal across every market. In practice, over-ear wireless models with long battery life and active noise cancelling — like the 780NC with Adaptive Noise Cancelling and up to 50 hours with ANC on — are the ones shoppers gravitate toward most in this tier.
Is the JBL Tune 780NC worth it over the Renewed 720BT?
In my opinion, yes — if you want adaptive noise cancelling, spatial audio, a wired Hi-Res path and better call mics. If you mainly want big bass and long battery on a tight budget, the Renewed 720BT is the smarter, simpler choice. Check the current price on Amazon for each before deciding.
