How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the lighter, more travel-friendly package with finer app control over how much of the world you let back in, choose Sony WH-CH720N; if you need marathon battery life and a deeper, softer fit for long listening sessions, choose Sennheiser Accentum.
• Sony WH-CH720N — biggest strength: Sony's lightest wireless noise-canceling design, with Dual Noise Sensor tech, a 20-level adjustable Ambient Sound mode, and a bundled stand and case in the box.
• Sony WH-CH720N — biggest trade-off: 35 hours of battery is solid but well short of the Accentum, and the all-plastic build keeps weight down at the cost of a more premium feel.
• Sennheiser Accentum — biggest strength: Up to 50 hours with Bluetooth and ANC on, a soft-touch silicone headband, deep ear pads, and a built-in 5-band EQ with Bass Boost and Podcast modes.
• Sennheiser Accentum — biggest trade-off: No 3.5 mm jack at all, so you're fully dependent on Bluetooth, and the 3-hour charge time is slower than Sony's quick-charge trick.
• Sony WH-CH720N is for you if: you switch between two devices all day, take calls in noisy rooms, and want granular control over ambient sound.
• Sennheiser Accentum is for you if: you listen for very long stretches, prefer a snugger fit with plusher padding, and want to tune the sound curve to your taste.
The WH-CH720N is built around the idea that noise canceling should be adjustable, not all-or-nothing. Sony puts two microphones in each earcup and pairs them with Dual Noise Sensor technology and an integrated processor, so ambient sound gets captured and canceled rather than just muffled. Where this headphone separates itself is the Ambient Sound mode: the feedforward and feedback mics feed the Sony Headphones Connect app, which lets you dial ambient sound across 20 levels and switch on a Focus on Voice setting so you can hold a conversation without pulling the headphones off. I think that flexibility is the single most useful feature here for anyone who works in a shared space or commutes through loud streets.
On the practical side, the CH720N pairs with two Bluetooth devices at once and lets you jump between them with a button press. Precise Voice Pickup Technology uses beamforming mics for calls, Adaptive Sound Control learns your behavior and adjusts volume based on where you are, and there's a 3.5 mm jack for wired listening when you want it. Battery life is rated at 35 hours, and a 3-minute USB-C charge gets you roughly 60 minutes of playback. The bundle adds a Deco Gear headphone stand, a hard case with a plush interior, and a microfiber cloth.
Who should skip it? If your priority is the longest possible time between charges, or if you want a headphone you can plug in and use passively with no battery at all, this isn't the one. The plastic build also won't feel as dense in the hand as the Sennheiser.
Sennheiser Accentum: Who It's For
The Accentum's defining number is 50 hours — that's battery life with Bluetooth and active noise canceling both running, on a single charge. If you're the type who charges a headphone once a week and forgets about it, or you take long-haul flights and don't want to think about a cable, this is the spec that decides it. The trade-off is charge speed: a full charge takes three hours, so you plan around it rather than topping up in a few minutes.
Sound customization is the second reason to pick it. Sennheiser fits the Accentum with 37 mm dynamic drivers and its own magnetic circuits, then hands you predefined audio modes — Bass Boost, Podcast mode — plus a built-in 5-band equalizer. That's a meaningful amount of control over the tuning, and it's the kind of thing that makes a headphone feel personal over months of use rather than just acceptable on day one.
Comfort leans soft. The headband uses soft-touch silicone, the ear pads are deep, and the whole thing is built on a lightweight ergonomic design at 222 g. Hybrid ANC handles the blocking, and Clear Mode lets you hear your surroundings with one touch instead of removing the headphones. Controls run through four buttons, with app-based wireless control for the finer settings, and it uses Bluetooth 5.2 with a 10-meter range.
Side-by-Side: Which Should You Choose?
• Best for battery life → Sennheiser Accentum. 50 hours with ANC on versus 35 hours on the Sony.
• Best for fast top-ups → Sony WH-CH720N. A 3-minute charge yields about 60 minutes of playback; the Accentum needs 3 hours for a full charge.
• Best for lightweight all-day wear → Sony WH-CH720N. Sony's lightest noise-canceling wireless model, with a slimmer headband and more ear room.
• Best for plusher padding → Sennheiser Accentum. Soft-touch silicone headband and deep ear pads at 222 g.
• Best for ambient-sound control → Sony WH-CH720N. 20 adjustable levels plus a Focus on Voice chat mode.
• Best for sound tuning → Sennheiser Accentum. Bass Boost, Podcast mode, and a 5-band EQ.
• Best for multi-device switching → Sony WH-CH720N. Simultaneous pairing with two Bluetooth devices and one-button switching.
• Best if you want a wired option → Sony WH-CH720N. It has a 3.5 mm jack; the Accentum has none.
• Best for out-of-the-box extras → Sony WH-CH720N. The bundle includes a headphone stand, hard case, and microfiber cloth.
In my opinion, the Sony WH-CH720N is the safer buy for most people. Dual-device pairing, a 3.5 mm jack, adjustable ambient sound across 20 levels, and a genuinely light build solve more everyday problems than a bigger battery number does. That said, if you know your routine is "charge on Sunday, use all week," I'd point you to the Sennheiser Accentum — 50 hours with ANC on is a real advantage, and the deeper pads and 5-band EQ make long sessions more enjoyable. Pick based on which of those two habits sounds more like you, then check the current price on Amazon before deciding.
