So you're googling headphones and ended up here. Good. In one corner of the ring is the Sony WH-1000XM5 – the world's best-selling noise-canceling headphone, whose model name basically requires a mnemonics course to remember. In the other corner, the Valco VMK25.2 – the headphone from a 14-person Finnish company, whose profits fund the Death Star and Henri's Alfa Romeo repair bills.
Let's see how these really stack up head-to-head.
Sound quality – this is where the game is decided
Let's say it straight: the VMK25.2 sounds better. Jasse "Jazmanaut" Kesti – the man whose ears are insured – has hand-tuned the frequency response so flat that audiophiles weep with emotion. 45-millimeter composite drivers and the Qualcomm chip with Jasse's own DSP tuning do exactly what they should: the music sounds like the artist intended.
Sony sounds perfectly fine. It's a mass-market product tuned to please as many ears as possible. A safe choice. A bit like white paint – no one complains, but no one gets excited either.
The VMK25.2's Class AB amplifier is another detail enthusiasts appreciate. Sony uses a digital amplifier. The difference is especially audible in the midrange and dynamics.
Noise canceling (ANC) – Sony's home field
We have to be honest here. Sony's ANC is a tad better. That's just how it is. Sony has spent millions developing it, and it shows.
The VMK25.2's hybrid ANC is still excellent. It handles airplane drone, office background noise, and traffic noise effectively. Both remove low frequencies – neither removes children's screaming or a coworker's nagging. That would require legal intervention, not headphones.
In practice, the difference is small. If you sit on airplanes 200 days a year, Sony's ANC might matter. If you sit in an office and want to focus, the VMK25.2 is more than enough.
Battery – this isn't even a contest
VMK25.2: 55 hours with ANC on. Sony: about 30 hours.
Read that again. 55 hours. That's Helsinki to Tokyo and back without charging. With the Sony, you're charging on the layover in Dubai.
Price – the elephant in the room
Sony WH-1000XM5 costs about 350–400 euros. VMK25.2 costs about half of that.
With the savings you could even get a second pair of VMK25.2s. Or donate the difference to our Death Star fund. Henri still needs a Ferrari for that corruption budget.
Repairability – this is where philosophies diverge
Sony's headphones are disposable electronics. Ear pad falls apart? Good luck. Headband snaps? New headphones.
On the VMK25.2, the ear pads come off with a bayonet mount and new ones snap into place. The side panels are magnetic – you can swap them or even 3D-print your own. If something actually breaks, Hannes repairs the devices in Kajaani. We don't throw headphones in the trash.
This is actually a big deal. 400-euro headphones that can't be repaired are 400-euro disposable goods.
Other differences in brief
- Bluetooth: VMK25.2 uses 5.4, Sony 5.2. In practice, both work well.
- Multipoint: Both connect to two devices simultaneously.
- Microphone: The VMK25.2 can be outfitted with an optional wireless boom microphone. In remote meetings it's on a different planet compared to built-in microphones.
- Weight: Both around 250–300 grams. Both fit well on the head.
Who should choose Sony?
If ANC is the absolute top priority for you and money is no object, Sony is a good choice. It's also a safe choice if you want to buy what everyone else buys. There's nothing wrong with that.
If you need headphones mainly for calls and use Apple's ecosystem, AirPods Max is also worth considering – although it costs even more and it can't be repaired either.
Summary
| | VMK25.2 | Sony WH-1000XM5 |
|---|---|---|
| Sound quality | Better | Good |
| ANC | Very good | Slightly better |
| Battery | 55h | ~30h |
| Price | ~170-200€ | ~350-400€ |
| Repairability | Yes | No |
| Model name memorability | Moderate | Impossible |
VMK25.2 wins in sound quality, battery, price, and repairability. Sony wins ANC by a small margin. You decide what matters most.
We naturally recommend the VMK25.2. We are biased, after all – those child support payments and Death Star building permits have to be funded somehow. But at least we're honestly biased.
Thanks for your money in advance.
