More plastic than a model kit workshop
Let us talk turkey. When I pull a piece of gear out of the box, the first thing I do is check the joints and the materials. The
Sony WH-CH720N is made of plastic. It is not the industrial-grade, reinforced resin I prefer, but it is functional. It keeps the weight down to a measly 192 grams, which is great for your neck if you wear these for long hours in the office or on a train. However, I always get a bit nervous when I see this much plastic in a hinge mechanism. If you are the type of person who throws your gear into a gym bag without a thought, you might be testing the structural integrity of these sooner than you want.
The design is minimalist, which I usually appreciate. Fewer moving parts often mean fewer things to break, but these do not fold up. You get a swivel, which helps them sit flat, but they are going to take up some real estate in your bag. The ear pads are synthetic leather. They feel soft enough out of the box, but keep an eye on them. Synthetic materials have a habit of peeling after a year or two of heavy use, especially if you have a bit of sweat or oil on your skin from working in the shop.
On the inside, it is a different story.
Sony put their V1 processor in here, which is the same chip they use in their much more expensive gear. That is a smart move. It means the digital signal processing is actually doing some heavy lifting. You are getting a clean, balanced sound right out of the box, and if you do not like the factory EQ, you can tweak it to your heart's content in the app. I like that; it shows they care about the user having control rather than forcing a specific sound profile down your throat.
The battery life is the real workhorse here. You get 35 hours with noise cancellation turned on. In the real world, that means you can go a whole week of commuting without needing to hunt for a charging cable. That is the kind of reliability I look for. It is not built like a tank, but it is built to get the job done for the average user who wants to tune out the world.
Repairability is always my big question. Since these are mostly snapped-together plastic components, doing a DIY repair on the internal battery or the drivers is going to be a headache. You are likely not going to be pulling these apart with a standard screwdriver set to replace a ribbon cable. It is a buy-it-for-a-few-years piece of tech rather than a family heirloom, but for the current price point, that is the trade-off you are making. Treat them with a little respect, and they will likely keep playing your tunes for a good long while.
Tech that actually earns its keep
The noise cancellation is surprisingly capable. They use a dual-microphone system that listens to the outside world and cancels it out before it hits your ears. It is not going to silence a jackhammer right next to you, but for the low hum of an airplane engine or the chatter in an open-plan office, it does exactly what it says on the tin. It is a solid, mid-tier implementation that makes a noticeable difference when you just need to focus.
Bluetooth multipoint is a feature I refuse to live without these days. Being able to connect to my laptop for a call and my phone for notifications simultaneously is a massive time-saver.
Sony nailed the implementation here. The connection is stable, and the switch between devices is quick enough that you will not be fumbling around when the phone rings. It is one of those small conveniences that makes you wonder how you ever lived without it.
The microphone quality for calls is another area where these hold their own. They use beamforming microphones and a structure designed to cut down on wind noise. If you are taking a walk outside, the person on the other end is not going to hear you sounding like you are standing in a hurricane. It is not studio-quality audio, but for meetings or catching up with a friend, it is clear and professional enough. It is a solid tool for the daily grind.
Verdict: A solid daily driver for the solo worker
If you are someone who works solo, commutes, or just wants to treat yourself to a decent pair of headphones without paying a month's rent, the
Sony WH-CH720N is a smart pick for Singles' Day. It is comfortable, sounds great, and the noise cancellation is reliable. If you are a heavy-duty user who needs gear that can survive a drop onto concrete or you demand a premium metal build, look elsewhere and prepare to spend double the cash. For everyone else, this is a solid, sensible investment.
