If you want maximum battery life and an over-ear design that stays comfortable for long listening sessions, choose Sony WH-CH720N-BLACK; if you need pocketable true-wireless earbuds with adaptive noise cancellation and a more personalized sound, choose Sennheiser MOMENTUM True.
• Sony WH-CH720N-BLACK — biggest strength: Up to 35 hours of battery with noise canceling on (up to 50 hours with it off), plus a 3-minute quick charge that yields up to 60 minutes of playback.
• Sony WH-CH720N-BLACK — biggest trade-off: It's a full-size over-ear headphone, so it's bulkier to carry and it relies on a headband-and-earcup fit rather than interchangeable tips.
• Sennheiser MOMENTUM True — biggest strength: Adaptive active noise cancellation that adjusts to your surroundings, plus a Transparency Mode and a 5-band EQ for tuning the sound to taste.
• Sennheiser MOMENTUM True — biggest trade-off: Roughly 30 hours of total playtime across the earbuds and charging case — meaningfully less listening time than the Sony set, and the earbuds are small enough to misplace.
• Who each pick is for: Choose Sony WH-CH720N-BLACK if battery endurance and over-ear comfort matter most; choose Sennheiser MOMENTUM True if you want compact earbuds with adaptive ANC and personalization.
The WH-CH720N is Sony's lightest wireless noise-canceling headphone, and that framing tells you a lot about the intended buyer. This is a set built around getting through a full day — a commute, a work shift, a long flight — without reaching for a charger. Sony rates battery life at up to 35 hours with noise canceling engaged, and up to 50 hours with it switched off. When you do run low, a 3-minute quick charge buys you up to 60 minutes of playback. That combination is the headline feature here, and it's the reason this pair makes sense for anyone whose priority is not thinking about charging.
On the noise-canceling side, Sony uses its Dual Noise Sensor technology paired with an Integrated Processor V1. The Ambient Sound mode is unusually granular: the Sony Headphones Connect app lets you dial ambient sound in 20 levels, and "Focus on Voice" lets you hold a conversation without pulling the headphones off. For calls, Precise Voice Pickup uses beamforming microphones to isolate your voice. Multipoint lets you stay connected to two Bluetooth devices at once, and DSEE upscales compressed audio to restore some of the high-frequency detail that gets stripped out. The driver is a 30mm dynamic unit with a 7Hz–20kHz range, and there's also a 3.5mm jack plus a 1.2m cable for wired listening when you want it.
Who should buy it: commuters, remote workers, students, and frequent travelers who want over-ear comfort, a long runtime, and wired backup. Who should skip it: anyone who wants earbuds small enough to slip in a pocket, or who prefers a fit that adjusts through interchangeable ear tips rather than a headband.

The MOMENTUM True Wireless 4 is the opposite philosophy: maximum technology in the smallest possible package. These are true-wireless earbuds with interchangeable ear adapters and soft silicone tips, designed for a secure fit that Sennheiser says stays comfortable over long sessions. Adaptive active noise cancellation automatically adjusts to your surroundings rather than sitting at one fixed level, and Transparency Mode brings outside sound back in at a touch — useful for hearing announcements or a barista without removing the earbuds.
The audio story is where Sennheiser leans hardest. The TrueResponse transducer system is paired with support for lossless audio up to 24-bit/96kHz resolution, and there's a 5-band EQ plus a Sound Personalization feature that calibrates a custom audio profile based on your reactions to a series of tones. The frequency range spans 6Hz to 22kHz. On connectivity, these support Bluetooth 5.4 with LE Audio and Auracast — the latter arriving via firmware update — which is the forward-looking part of the pitch for anyone who wants to share or stream audio in newer ways.
Battery life is up to 30 hours of total listening, and an 8-minute quick charge in the case delivers roughly an hour of playback. The charging case is included, along with a USB-C cable. Who should buy it: listeners who want the best possible sound customization in a pocketable form, people who move between environments and want ANC that adapts automatically, and anyone curious about LE Audio and Auracast. Who should skip it: heavy users who need maximum runtime per charge, or anyone who simply prefers the feel of full-size over-ear cups.
• Best for battery life → Sony WH-CH720N-BLACK. Up to 35 hours with ANC on and up to 50 hours with it off beats the roughly 30 hours of total playtime on the Sennheiser earbuds.
• Best for quick top-ups → Sony WH-CH720N-BLACK. A 3-minute charge gives up to 60 minutes of playback, versus 8 minutes for about an hour on the Sennheiser.
• Best for portable, pocketable use → Sennheiser MOMENTUM True. True-wireless earbuds with a charging case travel far more easily than a full-size headphone.
• Best for adaptive noise cancellation → Sennheiser MOMENTUM True. Its ANC automatically adjusts to your surroundings, while the Sony uses dual-sensor processing with app-controlled ambient levels.
• Best for sound personalization → Sennheiser MOMENTUM True. The 5-band EQ plus Sound Personalization calibration is a deeper customization toolkit than Sony's DSEE enhancement.
• Best for wired listening → Sony WH-CH720N-BLACK. It includes a 3.5mm jack and a 1.2m cable, so you can go passive when the battery is empty.
• Best for multipoint convenience → Sony WH-CH720N-BLACK. It pairs with two Bluetooth devices simultaneously for switching between a phone and a laptop.
• Best for future-facing connectivity → Sennheiser MOMENTUM True. Bluetooth 5.4 with LE Audio and Auracast support puts it ahead on emerging audio standards.
• Best for long-session comfort → Depends on your preference. Over-ear cups suit some listeners; others find silicone-tipped earbuds less fatiguing.
In my opinion, the Sony WH-CH720N-BLACK is the safer buy for most people. The battery advantage is enormous — up to 35 hours with noise canceling on versus roughly 30 hours total on the Sennheiser — and the wired 3.5mm backup plus multipoint pairing make it the more forgiving everyday companion. I'd pick the Sennheiser MOMENTUM True only if pocketability, adaptive ANC, and deep sound personalization matter more to you than runtime. Decide which of those two priorities sounds more like your day, and the choice becomes obvious.
Yes. Sony rates up to 35 hours with noise canceling on and up to 50 hours with it off, while Sennheiser rates up to 30 hours of total playtime. For long trips or all-day use without charging, the Sony has the clear edge.
They use adaptive active noise cancellation that adjusts automatically to your surroundings. Sony's WH-CH720N uses dual noise sensors with an integrated processor and lets you fine-tune ambient sound across 20 levels in its app. Both are strong; the Sennheiser adapts on its own, the Sony gives you more manual control.
Yes. It includes a 3.5mm headphone jack and a 1.2m cable, so you can listen passively without draining the battery. The Sennheiser MOMENTUM True has no headphone jack — it's wireless only.
That's a judgment call rather than a spec you can measure. Sennheiser emphasizes lossless audio up to 24-bit/96kHz plus a 5-band EQ and Sound Personalization, while Sony counters with DSEE enhancement for compressed tracks. If customization matters to you, I'd lean Sennheiser; if you want over-ear immersion and a wired option, I'd lean Sony. Check the current price on Amazon before deciding.
