How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want active noise cancelling with a cleaner, more precise sound for commutes and focused work, choose Sennheiser ACCENTUM; if you need marathon battery life, a foldable travel-friendly build and a wired fallback, choose JBL Tune 720BT.
• Sennheiser ACCENTUM – biggest strength: Hybrid active noise cancellation plus a transparency mode, so you can actually control how much of the world reaches your ears.
• Sennheiser ACCENTUM – biggest trade-off: Shorter rated battery life (up to 50 hours) and a slower full charge (about 3 hours).
• JBL Tune 720BT – biggest strength: Up to 76 hours of playtime, a 2-hour charge, and a 3.5 mm jack so you can keep listening even with a dead battery.
• JBL Tune 720BT – biggest trade-off: Only passive noise cancellation — there's no ANC engine to silence a plane cabin or a noisy bus.
• Who the ACCENTUM is for: commuters, students and office workers who want quiet on demand.
• Who the Tune 720BT is for: long-haul listeners, travellers and anyone who wants to go weeks between charges.
The ACCENTUM is the more "engineered" of these two. Its headline feature is hybrid noise cancellation — active circuitry rather than just padded earcups — paired with a transparency mode for when you need to hear an announcement or order a coffee without taking the headphones off. That combination is the whole reason to pick it over the JBL. If your day involves a train, a shared office or a loud café, ANC isn't a luxury; it's the feature that lets you drop the volume and still hear detail.
Sound-wise, Sennheiser leans on a 5-band EQ and adjustable sound modes through its app, with a dynamic driver covering 10 Hz to 22 kHz. That lower frequency floor is worth noting — it suggests the ACCENTUM is aiming for deep bass extension alongside clarity in the highs, and the EQ gives you room to nudge the tuning toward your taste rather than living with a fixed signature. Calls get dual-microphone beamforming, which is the sensible choice for anyone taking meetings from a headset rather than a phone held to their ear.
Comfort is clearly a design priority: cushioned earcups and a soft-touch, silicon-lined headband meant to hold a secure fit through a long day. Bluetooth 5.2 handles pairing, the controls run through the app, and the box includes a USB-C cable and a carrying pouch. At 7.68 ounces it's a normal over-ear weight, and the 1-year manufacturer warranty matches the JBL.
JBL Tune 720BT: Who It's For
The Tune 720BT plays a different game entirely: endurance and flexibility. Up to 76 hours of playback on a 2-hour charge is the standout number, and the quick-charge claim — a 5-minute top-up for roughly 3 extra hours — is genuinely useful when you've forgotten to plug in the night before. For a student, a long-haul flyer or someone who simply resents charging cables, that changes the ownership experience more than any tuning tweak.
Instead of ANC, JBL relies on passive noise cancellation — the physical seal of the earcups — and puts its effort into JBL Pure Bass Sound, a bass-forward signature the brand is known for. Whether that suits you is a taste question: it's a punchier, more coloured sound than the Sennheiser's adjustable, EQ-tunable approach. Bluetooth 5.3 is the newer standard of the two, and the free JBL Headphones app gives you an EQ plus voice prompts in your chosen language to walk you through features.
Two practical details stand out. The 3.5 mm jack means you can run these wired when the battery is empty or when you want zero wireless latency — a real advantage the ACCENTUM doesn't offer, since its only connection is Bluetooth. And the flat-folding design packs down into a backpack far more easily than a rigid over-ear. Controls are on the ear-cup, calls use Voice Aware so you hear your own voice while talking, and the bundle includes a detachable audio cable, USB-C cable and documentation. It weighs 7.8 ounces and carries a 1-year warranty for the manufacturer.
Who should buy it: anyone who values battery life, a wired backup and an easy-to-pack shape. Who should skip it: if blocking out engine noise or open-plan chatter is the point, passive sealing alone won't match active cancellation.
• Best for noise cancelling → Sennheiser ACCENTUM. Hybrid ANC plus transparency mode is a feature set the JBL simply doesn't have.
• Best for battery life → JBL Tune 720BT. Up to 76 hours versus up to 50 hours is a wide gap, and the JBL also charges faster.
• Best for commuters and open offices → Sennheiser ACCENTUM. This is exactly the scenario active cancellation was built for.
• Best for travel and packing → JBL Tune 720BT. The flat-folding design is friendlier to a backpack than a fixed over-ear.
• Best for wired listening → JBL Tune 720BT. A 3.5 mm jack means it works with no battery at all; the ACCENTUM is wireless-only.
• Best for sound tailoring → Sennheiser ACCENTUM. A 5-band EQ and multiple sound modes give you more control over the tuning.
• Best for punchy bass out of the box → JBL Tune 720BT. Pure Bass Sound is the signature here, not a neutral presentation.
• Best for calls → Sennheiser ACCENTUM. Dual-microphone beamforming is the more purpose-built setup for voice transmission.
In my opinion, the Sennheiser ACCENTUM is the one I'd buy — if quiet is what you're actually shopping for. Hybrid ANC and a transparency mode change how you use headphones on a commute, in an office or on a plane, and no amount of battery life replaces that. The 50-hour rating with a 10-minute fast charge is more than enough for a normal week. I'd only steer you to the JBL Tune 720BT if you genuinely need the 76-hour runtime, want a wired fallback, or prefer a bass-forward sound and a foldable shape. Between the two, the ACCENTUM is the more capable daily driver for most people.
Not universally. The ACCENTUM wins on active noise cancellation, transparency mode and call microphones. The JBL wins on battery life, charge speed and wired connectivity. It comes down to whether you want quiet or endurance.
No. It uses passive noise cancellation — the natural seal of the earcups — rather than an active ANC system. That means it dulls some ambient sound but won't silence an engine drone the way the ACCENTUM's hybrid ANC can.
The JBL Tune 720BT, clearly: up to 76 hours versus up to 50 hours for the ACCENTUM. The JBL also fully charges in about 2 hours against roughly 3 for the Sennheiser.
The JBL Tune 720BT, yes — it has a 3.5 mm jack and ships with a detachable audio cable, so it still works with no charge. The Sennheiser ACCENTUM is Bluetooth-only, so you'll want to keep an eye on the battery.
For commuting specifically, I'd take the ACCENTUM — hybrid ANC and transparency mode are made for trains, buses and busy streets. Pick the JBL Tune 720BT if you'd rather charge once a week and want a wired option as insurance.
If you're weighing value, check the current price on Amazon before deciding — both sit in the affordable over-ear bracket, and the better buy for you depends on whether ANC or battery life matters more.
