Look, the Bose QuietComfort 25 is basically a dinosaur in the tech world. In a market where we're obsessed with transparency modes, multipoint Bluetooth, and USB-C fast charging, a pair of wired headphones that runs on a literal AAA battery seems like a relic. It’s weird. It’s old.
But here is the thing.
I was sitting on a flight recently next to someone wearing the latest $500 Sony cans, and honestly? My ten-year-old QC25s were doing just as good a job at killing that low-frequency engine hum. Better, maybe. There is a specific kind of magic in how Bose tuned these things before they got distracted by touch controls and app integrations. The Bose QuietComfort 25 represents a peak in utilitarian design that we just don't see anymore. It wasn't trying to be a lifestyle accessory; it was a tool for people who hated noise.
The AAA Battery Factor: Why Being "Old School" is a Secret Weapon
Most people think the lack of a rechargeable internal battery is a dealbreaker. They're wrong. If you’ve ever been halfway across the Atlantic and realized your headphones are at 2%, you know the panic. With the Bose QuietComfort 25, you just reach into your bag, swap a single AAA battery, and you’re back at 100% in exactly twelve seconds. It’s glorious.
Think about the lifespan of your gadgets. Most modern wireless headphones are essentially disposable. Once that internal lithium-ion battery degrades after three or four years of heavy use, the headphones are e-waste. You can't easily swap them. But the QC25 doesn't have that "death date" baked into its hardware. As long as you have a cord and a battery, they work.
I’ve seen enthusiasts on forums like r/headphones or Head-Fi who have kept a single pair of these running for nearly a decade. They just swap the ear pads when the faux leather starts to flake—which, admittedly, it does—and they keep going. It’s a level of sustainability that Bose probably didn't even intend, but it’s a massive win for anyone tired of the "buy-break-repeat" cycle of modern consumer electronics.
Noise Cancellation That Actually Matters
We need to talk about the ANC (Active Noise Cancellation). Newer models like the Bose QuietComfort Ultra or the Sony WH-1000XM5 are technically "better" at blocking out human voices or high-pitched screeching. They have more microphones. They have faster processors.
But the Bose QuietComfort 25 was built specifically to dominate the 100Hz to 1kHz range. That is the "drone zone." It’s the sound of an air conditioner, a bus engine, or a data center. For those specific frequencies, the QC25 is still a heavyweight champion.

It doesn't have that "pressure" feeling in the ears that some people complain about with newer, more aggressive ANC systems. It feels natural. Sorta like stepping into a library. You still hear the world, but the world is just... quieter. It isn't trying to create a silent vacuum that makes you feel dizzy. It’s just lowering the volume of the annoying stuff.
The Cord is a Feature, Not a Bug
Yeah, it has a wire. I know. It’s 2026 and we hate wires. But have you ever tried to watch an in-flight movie with Bluetooth headphones? You can't. Not without a clunky third-party adapter that probably has lag anyway. The Bose QuietComfort 25 comes with that classic 2.5mm to 3.5mm cable and a dual-prong airline adapter.
It just works. No pairing. No "searching for devices." No firmware updates that suddenly break your connection.
Also, the audio quality over a wire is objectively more consistent. You aren't dealing with AAC or LDAC compression. You're getting the raw signal. While the QC25 isn't "audiophile" grade in the sense of a high-end Sennheiser open-back, it has a very pleasing, warm sound signature. It’s designed for long-term listening. You can wear these for six hours and your ears won't feel fatigued by sharp treble or booming, fake bass.
What Most People Get Wrong About the Build Quality
There’s this myth that because the QC25 is mostly plastic, it’s cheap.
That’s a misunderstanding of engineering. These things were built to be folded, crammed into a tiny carrying case, and tossed into a backpack. The "glass-filled nylon" and stainless steel hinges are incredibly resilient. Unlike the Bose 700s, which have a sleek but somewhat stiff headband, the QC25 has a lot of flex.
- It weighs almost nothing (about 6.9 ounces).
- The headband uses Alcantara—the stuff they put in luxury car interiors.
- The earcups pivot in every direction.
If you drop a pair of heavy, metal-clad headphones, the weight actually works against them, causing things to snap. If you drop the QC25, it sort of bounces. It’s the "Crumple Zone" philosophy applied to audio gear.

The Reality of the "Used" Market
You can find these at thrift stores, on eBay, or on Facebook Marketplace for anywhere from $40 to $80. Compare that to the $350+ price tag of new flagship ANC headphones.
Is the new stuff 5 times better? No way.
Honestly, it’s maybe 15% better in terms of pure noise reduction and obviously much better for features like "Find My" or voice assistants. But if your goal is just to study in a noisy dorm or sleep on a plane, the value proposition of the Bose QuietComfort 25 is unbeatable.
Common Issues to Watch For
If you are going to go the used route, you need to be smart. There are three things that usually go wrong:
- The Ear Pads: The original Bose pads are notorious for disintegrating. Don't worry about it. You can buy third-party replacements for $15 that are actually sometimes more comfortable than the originals.
- The Battery Door: It’s a tiny plastic hinge. If the previous owner was a brute, it might be loose. Check that.
- The "One-Ear" Failure: Sometimes the internal wiring in the swivel can fray, leading to sound cutting out in one ear. Give the cups a good wiggle while playing music to make sure the connection is solid.
Dealing with the "Apple Problem"
If you have an iPhone, you probably don't have a headphone jack. This is the biggest hurdle for the Bose QuietComfort 25 today. You have to carry the "dongle."
It’s annoying, but here’s a pro tip: just leave the Apple Lightning or USB-C to 3.5mm adapter permanently attached to the Bose cable. Now it’s just a "Phone-Compatible" cable. Problem solved.
I’ve actually found that using the wired connection saves a massive amount of battery life on my phone during long trips. Bluetooth is a power hog. Direct analog output isn't. It’s a weirdly effective way to make your phone last through a cross-country trek.

Why the QC25 Matters in a World of Distraction
There is something to be said for "Single Task" devices.
When you put on a pair of modern smart headphones, you're interacting with an OS. You're hearing notifications. You're toggling between "Awareness Mode" and "Focus Mode."
With the Bose QuietComfort 25, there is exactly one switch. On. Off.
That’s it.
When you flip that switch, the world goes quiet. You don't have to talk to an app to adjust the EQ. You don't have to worry about a battery percentage. You just do your work. In a world that is constantly trying to grab our attention with pings and updates, the simplicity of this headset is actually its most "premium" feature.
It stays out of your way.
Actionable Steps for Potential Owners
If you're looking to pick up a pair or dig your old ones out of the closet, do this:
- Upgrade the pads immediately. Look for "protein leather" or cooling gel pads from brands like Wicked Cushions. They breathe better than the stock ones.
- Use Eneloop rechargeable AAAs. Don't keep buying disposables. A 4-pack of high-quality rechargeables will last you years and save you a fortune. Keep a spare in the dedicated slot in the Bose carrying case.
- Get a Bluetooth Transmitter/Receiver. If you absolutely MUST have wireless sometimes, you can buy a tiny $20 Bluetooth adapter that plugs directly into the 2.5mm port on the ear cup. It turns the QC25 into a wireless headset for those times you're at the gym or moving around the house.
- Check the Serial Number. If buying used, verify the serial under the "scrim" (the fabric inside the ear cup) on the Bose website to ensure they aren't counterfeits. Yes, people actually made fakes of these because they were so popular.
The Bose QuietComfort 25 isn't the future of audio. It’s something better. It’s a proven, reliable, and fixable piece of tech that does one thing incredibly well. In 2026, that feels like a radical concept. Turn the noise off. Focus. It really is that simple.
