I’ll just say it: most people shouldn't buy the newer model. It’s been years since the Sony WH-1000XM4 first hit the shelves, and the tech world usually moves on faster than a TikTok trend. But walk through any airport terminal or a quiet university library today, and you’ll still see that familiar copper-accented logo everywhere. There’s a specific reason for that. Sony accidentally built a "forever" product.
It’s weird.
Usually, when a successor like the XM5 comes out, the older version feels like a relic. It gets clunky. The software starts to chug. But the Sony WH-1000XM4 has this strange staying power because it solved the comfort-to-performance ratio in a way that’s actually pretty hard to beat, even with 2026's latest silicon.
The Folding Problem Nobody Mentions
If you travel, you know. Space is everything.
The biggest gripe I have with modern premium headphones is that they’ve stopped folding. Sony’s newer flagship has a rigid headband. It’s "sleek," sure, but it takes up a massive footprint in a backpack. The Sony WH-1000XM4, however, still uses that classic hinge design. They collapse into a tight, rugged little ball. You can shove them into a side pocket or their slim hardshell case without feeling like you’re carrying a dinner plate.
It’s a design choice that prioritizes the commuter over the aesthetician.
I’ve seen people complain that the hinges are a failure point. Honestly? Only if you’re throwing them across the room. In four years of heavy use, the most I’ve seen is a bit of creaking that a tiny drop of silicone lubricant fixed in five seconds. They feel dense. They feel like they were made to be used, not just looked at on a desk.
That Specific Noise Canceling Magic
Let’s talk about the QN1 processor.
When Sony dropped this chip, it changed the game for how we handle high-frequency sounds. Most noise-canceling cans are great at blocking out the low drone of a jet engine. That’s easy. It’s the "whoosh." But the Sony WH-1000XM4 uses Dual Noise Sensor technology to sample ambient sound 700 times per second.

It catches the screech of a subway brake. It catches the annoying guy in the cubicle next to you talking about his crypto portfolio.
Is it the absolute "best" in the world today? Probably not if you’re measuring with lab equipment. Bose has made strides. Apple’s AirPods Max have that weirdly natural transparency mode. But for pure isolation—that "I am underwater and the world is gone" feeling—the XM4 remains a heavyweight champion.
The secret sauce is the atmospheric pressure optimizer. If you fly often, you’ve felt that "plugged ear" sensation with ANC. Sony put a tiny sensor inside these that adjusts the internal pressure based on the altitude. It sounds like a gimmick until you’re at 30,000 feet and your head doesn't feel like it’s in a vice.
Why the Sound Signature is Polarizing
Audiophiles love to argue. It’s what they do.
If you go on r/headphones, you’ll see people trashing the Sony WH-1000XM4 for being "muddy." And yeah, out of the box, Sony cranks the bass. It’s a warm, consumer-friendly sound. It makes hip-hop and EDM feel physical. But if you’re listening to a delicate folk track, that low-end can bleed into the vocals.
The fix is simple, though. Use the Headphones Connect app.
- Clear Bass: Drop it to -2.
- 400Hz: Bump it slightly.
- 2.5kHz: Add a little sparkle.
Suddenly, you have a pair of headphones that rivals much more expensive wired sets. They support LDAC, which is Sony’s proprietary codec that allows for roughly three times the data of standard Bluetooth. If you’re using Tidal or Qobuz, or even just high-bitrate Spotify, you can actually hear the texture of a guitar string vibrating. Most people just leave them on the default settings and miss out. Don't be that person.
The Multi-Point Struggle is Over
Before the XM4s, you had to manually disconnect from your laptop to answer a call on your phone. It was a nightmare.

The Sony WH-1000XM4 was one of the first to really nail multipoint connection. It stays paired to two devices simultaneously. It’s smart enough to know that if you’re watching YouTube on your MacBook and a call comes in on your iPhone, it needs to swap the audio source instantly.
It isn't perfect. Sometimes, a random notification on your phone will hijack the audio for a split second while you're in a Zoom meeting. It’s annoying. But compared to the "forget device" dance we used to do, it’s a miracle.
What Most People Get Wrong About Speak-to-Chat
There is a feature on these headphones that everyone turns off immediately. It’s called Speak-to-Chat.
The idea is that if you start talking, the music pauses and the microphones pipe in the outside world so you can have a conversation. In theory, it’s brilliant. In practice, if you clear your throat or hum along to a song, the music cuts out.
It’s the most polarizing feature Sony ever invented.
But here is the trick: if you work in an office where people constantly "pop by" your desk, it’s actually a lifesaver. You don't have to reach for a button. You just say "Hey" and the headphones do the work. If you hate it, just hold two fingers to the right earcup to toggle it off. Most reviewers act like it’s a dealbreaker, but it’s just a tool you have to learn how to use.
Battery Life and the 10-Minute Rule
We’re at a point in tech where battery life is mostly a solved problem, but it’s still worth noting. You get 30 hours with ANC on.
That’s enough for a flight from New York to Singapore and back, with juice left over for the Uber ride home.

The real winner is the fast charging. 10 minutes on a USB-C cable gives you five hours of playback. I can’t count how many times I’ve realized my headphones were dead right as I was leaving for the gym, plugged them in while I found my shoes, and had enough power for the whole workout. It removes the "battery anxiety" that usually comes with wireless gear.
The Longevity Factor: Maintenance and Pads
Let’s talk about the gross stuff. Earpads.
Synthetic leather dies. After about 18 months of daily use, the pads on the Sony WH-1000XM4 will likely start to flake or lose their seal. This is where most people throw their headphones away and buy new ones.
Don't.
The pads are replaceable. You can buy third-party cooling gel pads for twenty bucks that actually make the headphones more comfortable than they were on day one. Because this model is so popular, the aftermarket for parts is huge. You can find replacement batteries, headbands, and even internal ribbon cables. These are "repairable" in a way that many modern, glued-together tech products aren't.
Real-World Use Cases
- The Student: Deep work in a loud cafeteria is possible.
- The Remote Worker: The mic quality is "okay" (not great, honestly), but the noise cancellation ensures you can actually hear your boss.
- The Traveler: The folding design is the gold standard.
Is there a downside?
Nothing is perfect. The Sony WH-1000XM4 isn't water-resistant. If you get caught in a downpour or sweat excessively during a heavy cardio session, you risk frying the internals. They are "dry land" headphones.
The touch controls can also be finicky in cold weather. If you’re in sub-zero temperatures, the capacitive sensors on the earcups sometimes register "ghost touches," skipping tracks or changing volume on their own. It’s a known quirk. If you live in a frozen wasteland, you might want physical buttons.
Actionable Steps for New Owners
If you just picked up a pair or you’re looking at a refurbished deal (which are currently the best value in audio), do these three things immediately:
- Download the Sony Headphones Connect App: Don't skip this. You need it for firmware updates that improve connection stability.
- Run the Noise Canceling Optimizer: Every time you change your environment (like getting on a plane), go into the app and run the optimizer. It tones the ANC to your specific fit and the local air pressure.
- Toggle the "Automatic Power Off": By default, they turn off when you take them off. If you want to use the ANC just for quiet (without music) while you sleep on a plane, you need to change this setting so they stay active even when they aren't on your head.
The Sony WH-1000XM4 doesn't feel like a "budget" alternative to the XM5. It feels like a different philosophy of design—one that values portability and utility over a futuristic silhouette. For most people, that’s exactly what matters.
