Sony WH-CH720N Wireless On-Ear Headphones with Noise Canceling, Bluetooth, Mic, and Built-In Alexa (Black)

What you get (and what it’s built to solve)

Sony’s WH-CH720N is an over-ear, wireless Bluetooth headset designed for everyday listening where noise gets in the way. The big promise here is noise canceling plus a comfortable, lighter-than-you’d-expect fit, so you can stay in your music (or calls) without feeling weighed down.

On paper, it’s aimed at people who want a feature-rich, modern experience—adaptive sound behavior, adjustable ambient sound, and practical call pickup—without stepping into the most expensive “flagship only” territory. The only catch: if you’re the kind of listener who demands the strongest possible active noise canceling above all else, you’ll want to be thoughtful about expectations, since this is positioned as a comfort-and-value focused model.

The essentials: noise canceling, awareness modes, and Sony’s V1 processor

Where this headset stands out is the noise canceling system powered by Sony’s built-in V1 processor. The goal is simple: reduce distractions so you can actually enjoy the music instead of battling the environment.

You also get adjustable ambient sound mode, which matters a lot if you commute or walk around outside. Being able to dial in how much outside sound you hear can make the difference between “fully isolated” and “safe enough to stay aware.”

There’s also an adaptive sound control feature with a “sound tailored to your environment” approach. Again, that’s about convenience—let the headset respond to what’s around you rather than forcing you to manually micromanage every setting.

And yes, there’s a built-in Alexa. If you already use Alexa on your phone or at home, that integration is one of those practical perks you might actually use more often than you expect.

Comfort and battery life you can plan around

Sony emphasizes a light, comfortable design. Over-ear headphones can get fatiguing fast, especially for longer sessions, so this is one of the more convincing reasons to take a look.

Battery life is rated up to 35 hours, and the headset supports fast charging. Sony specifies a short charge—3 minutes—can provide up to 1 hour of playback. That’s the kind of feature that shows up in real life: if you forget to charge overnight, a quick top-up before heading out can save the day.

Sound features: balanced tuning, DSEE, and how it helps compressed audio

Sony calls out high-quality sound and well-balanced tuning. That’s a helpful starting point if you’re tired of headphones that sound fun for a few minutes and then feel off during long listening.

There’s also DSEE, which Sony describes as increasing the quality of compressed music files. If you stream using formats that can be compressed, DSEE can be a useful “background improvement” rather than a night-and-day transformation. It’s more about making your everyday library sound better than about creating studio-level magic from scratch.

If you care about streaming clarity, the headset is also described as delivering high-quality sound through DSEE for music streaming.

Calls, voice pickup, and multipoint Bluetooth

For calls, you’re covered with hands-free calling and a built-in voice assistant setup that uses precise voice pickup technology. In practical terms, this is meant to reduce the “hello—can you repeat that?” moments.

The multipoint connection is another real-world win: you can switch quickly between two devices at the same time. That’s great if you bounce between a laptop and phone during a workday, or if you want music from one device while staying reachable on another.

One limitation to keep in mind: multipoint is convenient, but it can still depend on how your devices handle Bluetooth switching. If your setup is complex, it’s worth paying attention to whether both devices behave the way you expect.

Where it fits best (and when you may want to look elsewhere)

It makes sense if you want a comfortable, wireless headset with noise canceling, an ambient mode you can adjust, and an everyday-friendly battery life. It’s especially compelling for commuters, students, and office users who want practical features like hands-free calls, Alexa, and multipoint without making the listening experience feel like a chore.

It might not be the best choice if you’re chasing maximum, no-compromises noise canceling performance above everything else, or if you only buy headphones for the most detailed, audiophile-grade tuning. In those cases, you may want to compare against options that are built and marketed specifically for that top-end noise canceling focus.

Should you buy it?

Final verdict

Buy the Sony WH-CH720N if you’re looking for a light, comfortable wireless headset that targets real daily problems: noisy surroundings, short-notice charging, and juggling calls and devices. The combination of V1-powered noise canceling, adjustable ambient sound, and multipoint makes it feel built for commuting and work routines.

Skip it if your priority is extreme noise canceling performance or if your expectations are firmly set on “best-in-class” sound above all else. In that scenario, it’s worth comparing with options that are more narrowly optimized for the audio/noise performance you want.
