How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the lightest option with the most granular ambient-sound control and a full EQ toolkit, choose Sony WH-CH720NL; if you need the longest battery life with fast charging, a hybrid ANC system and a transparency mode, choose Sennheiser Sennehiser ACCENTUM.
• Sony WH-CH720NL — biggest strength: a genuinely light 192 g over-ear build paired with deep app-based tuning, including 20 ambient-sound levels and EQ adjustment.
• Sony WH-CH720NL — biggest trade-off: its listed battery figure is confusing, with the spec sheet showing both a headline 35-hour rating and a description touting up to 50 hours, so you should treat the shorter number as the safe expectation.
• Sennheiser Sennehiser ACCENTUM — biggest strength: up to 50 hours of playback with a 1-hour charge time, plus hybrid ANC and a transparency mode for when you need to hear the world around you.
• Sennheiser Sennehiser ACCENTUM — biggest trade-off: it is the heavier of the two at 222 g, and it leans on touch controls rather than physical buttons.
• Pick the Sony if you want the lighter fit, physical buttons, multipoint and an app that lets you dial in sound precisely.
• Pick the Sennheiser if you want maximum time between charges, quick top-ups, and a simple ANC/transparency toggle.
The WH-CH720NL is Sony's lightweight everyday over-ear. At 192 g it is the lighter of these two headphones, and Sony builds the whole pitch around that: a lightweight ergonomic construction designed so the headphone stays comfortable across long listening sessions. If you wear headphones for hours at a desk, on commutes, or through a long workday, that weight difference is the kind of thing you notice by hour three.
The feature set is unusually deep for this tier. Inside is the Integrated Processor V1, the same processor Sony uses in its flagship line, paired with the Digital Sound Enhancement Engine to bring compressed digital files closer to the original recording. Noise cancelling is handled by Dual Noise Sensor technology, and here is the standout detail: through the Sony | Headphones Connect app you can adjust ambient sound across 20 different levels. That is far more granular than the usual on/off/transparency toggle. You also get custom EQ, 360 Reality Audio certification, multipoint connection to two Bluetooth devices at once, Swift Pair and Fast Pair for quick setup, and voice control. On calls, Precise Voice Pickup Technology, a wind noise reduction structure and beamforming mics work together to keep your voice clear.
One honest caveat about the data: the Sony sheet lists a battery average life and charge time of 35 hours while the product description mentions up to 50 hours. That inconsistency means I would plan around the lower, more conservative number rather than the marketing figure.
Sennheiser Sennehiser ACCENTUM: Who It's For
The ACCENTUM is the endurance play. Sennheiser rates it at up to 50 hours of battery life on a single charge, and the charge time is listed at just 1 hour — a combination that matters if you are the kind of person who forgets to plug things in until the battery warning appears. A short top-up gets you back to listening, and a full charge covers a workweek of commuting or a long-haul trip without a cable.
Sound is handled by 42 mm dynamic transducers with a 5-band EQ and customizable sound modes through the Sennheiser Smart Control app. Noise cancelling is hybrid ANC, and critically, Sennheiser pairs it with a transparency mode so you can let the outside in without pulling the headphones off — useful for airport announcements, office conversations, or crossing a street. Calls run through dual-microphone beamforming, which is the same basic approach Sony takes, aimed at keeping your voice intelligible on the other end. Multipoint connectivity lets it hold two devices at once, touch controls handle playback, and the cups fold flat into an included case.
On comfort, Sennheiser describes a lightweight ergonomic design with a soft-touch silicone-lined headband for a secure fit. Note that at 222 g it is about 30 g heavier than the Sony, so "lightweight" here is relative. The materials and the fold-flat design suggest a headphone built to travel, and the 2-year manufacturer warranty backing is a meaningful detail for a product you plan to toss in a bag.
Who should buy it? Travelers, hybrid workers and anyone who measures a headphone by how rarely it needs charging. The transparency mode and hybrid ANC make it a strong fit for people who move between noisy and quiet environments all day. Who should skip it? If you are sensitive to weight on your head over very long sessions, the Sony is the lighter option. And if you prefer tactile buttons over touch controls — especially with gloves on in winter — the Sony's button operation is the friendlier design.
• Best battery life → Sennheiser Sennehiser ACCENTUM. Up to 50 hours versus the Sony's listed 35.
• Fastest recharge → Sennheiser Sennehiser ACCENTUM. A 1-hour charge time is dramatically shorter than the Sony's listed 35 hours.
• Lightest on your head → Sony WH-CH720NL. 192 g against 222 g.
• Most control over ambient sound → Sony WH-CH720NL. 20 adjustable levels in the app, versus a standard ANC/transparency pairing on the Sennheiser.
• Best for button lovers → Sony WH-CH720NL. Physical button operation plus voice control, rather than touch surfaces.
• Best for travel and commuting → Sennheiser Sennehiser ACCENTUM. Fold-flat cups, an included case and transparency mode for navigating the world mid-journey.
• Best for deep sound customization → a tie, leaning Sennheiser. Sony offers a full EQ and 360 Reality Audio; Sennheiser counters with a 5-band EQ and sound modes.
• Best for call clarity → effectively a tie. Both use beamforming microphone arrays and wind/noise handling aimed at clearer voice pickup.
If I had to pick one for myself, I would take the Sennheiser Sennehiser ACCENTUM. In my opinion, the 50-hour battery life and 1-hour charge time are the two specs that quietly change how you live with a headphone — you stop thinking about charging entirely, which is worth more day to day than a 30 g weight difference. The hybrid ANC plus transparency mode also covers more real situations, from a loud cabin to a quiet office. That said, if you know you are weight-sensitive or you want to fine-tune ambient sound across 20 levels and prefer real buttons, the Sony WH-CH720NL is the better fit for you, and I would not argue against it. Check the current price on Amazon before deciding, since value is the one thing specs alone cannot settle.
Yes, on the listed figures. Sennheiser rates the ACCENTUM at up to 50 hours with a 1-hour charge time, while the Sony sheet lists 35 hours for both playback and charge time. If battery endurance is your priority, the Sennheiser is the clear choice.
The Sony WH-CH720NL is lighter at 192 g. The Sennheiser ACCENTUM is listed at 222 g. If you wear headphones for many hours and weight is your main comfort concern, the Sony has the advantage on paper.
Both use active noise cancelling — Sony's Dual Noise Sensor system with the Integrated Processor V1, and Sennheiser's hybrid ANC. The real difference is control: Sony lets you adjust ambient sound across 20 levels in its app, while Sennheiser pairs its ANC with a transparency mode. Neither sheet gives a measured cancellation figure, so I would judge them on flexibility rather than claiming one blocks more noise.
Yes. Both the Sony WH-CH720NL and the Sennheiser ACCENTUM support multipoint connection, so you can stay linked to a phone and a laptop simultaneously and switch between them without repairing.
