Review: Bose QuietComfort 25 – The Silence is Deafening

It seems odd that there are no good reviews of the new Bose Quiet Comfort 25, or QC25, out there. I hope this helps you – I bought these on the first day they came out and have been living with them for a short while now.

I’ve always been an audio fanatic, right from my childhood. The audio world has changed enormously in the last 15 years. Gone are the days when I would frequently sit at a desk at home with a CD player and listen to music on wired headphones. Gone are the days when I frequently sit at a desk at home listening to music!

These days, I mostly listen to music when traveling, in inhospitable locations and carrying a heavy load. Back in 1998 I bought a pair of Sennheiser HD-600 headphones, which have exquisite sound quality. They’re useless in this post-modern age of commuter flights because they are open backed, which means your music leaks, and the world leaks into your ears.

My last pair of noise canceling headphones were lost and so in early September 2014, I walked through an airport terminal and spotted the QC25 on a shelf. They are understated, subtle, and very compact. I was immediately drawn to them.



Noise Canceling

I headed over to try them on and was somewhat underwhelmed – then I realize that the Active Noise Canceling (ANC) was switched off. I hit the switch and the world turned off. Gone was the loud terminal noise, and I was in a small quiet world of my own. Incredible. I listened to a few tracks of music and realized these would make my long weeks of travel much more pleasurable.

For that is where the QC25 excels: commuters, in planes and trains. It completely destroys hums and groans and aircraft engines and air conditioners. For people and voices, it’s not as strong, but no ANC headphone is. But it is better than any other headphone on the market at ANC. The silence is deafening.


I’ve never been a huge fan of the Bose sound and the QuietComfort25 is no surprise here. The music is “OK” – the saxophone on Dire Straits’ Your Latest Trick comes out nicely, and the coins clink melodically in Pink Floyd’s Money. Turn up the bass a little with Faithless’ God is a DJ and the Bose is in its comfort zone: HiFi, this is not.

But then you sit down in a seat of a plane and flip the switch, and the world turns off again. In that moment, you forgive the slightly brash mid-tones and slightly wooly base. This is a world of trade-offs and the QC25 delivers a wonderful balance.

The crucial point is because it is so quiet in your cocoon, you can turn the music down and hear details that you never hear from regular headphones. They sound much better than they have any right to sound when you are in a public place.

Living with the QC25

The packaging is exceptionally easy to live with, they fit into an 8.25″x5.75″x2″ box which fits nicely in a laptop bag, and it fits an airplane adapter and a spare AAA battery. Bose say it lasts 35 hours, but I’m not counting. One spare battery is enough for a week away from home.

The fit is sublime with a “protein leather” (an artificial, leather-like material that absorbs some sweat) covering. The 6.9oz cans fit comfortably on the head for long periods of time – say a 3-4 hour flight, or a noisy office day.

There’s a replaceable 4’8″ cable with a microphone for phone calls and a volume/call switch, which is useful if you want to listen to music on your iPhone and don’t want to switch cables when a call comes in. You can turn off the ANC during phone calls so your voice doesn’t sound weird.

Bose make a big deal about this because the headphone continues to run even after you run out of battery (unlike the QuietComfort15) but the audio kinda sucks without the ANC, so I’m not so certain how useful that is (unless you want to make a call!).

QuietComfort 15 Owners

I suspect a lot of people who own QC15s are wondering if they should upgrade. I’ve used both headphones – a lot of airlines provide QC15s on long haul flights, and they are most excellent. The QC25s are easier to live with – they are smaller and more comfortable – but if I had spent good money on QC15s, the difference between the two models is not worth the price of a new pair.


One negative I found was that sometimes the headphone can motorboat – it starts to make a weird noise in the right ear. This must be an unintentional side-effect of the ANC technology, and may be a teething problem with the first few pairs. If it continues, I’ll call Bose.

There’s also a slight air pressure thing going on when you wear them. ANC headphones change the air pressure around your ears, and that can be bothersome.


If you are a traveler, commuter, spend time on a plane, or in a loud office, or outside, then go and try these out. They are the gold standard in Noise Canceling Headphones. They trash Sennheiser, Beats (yuck), Parrot and everyone else in this respect.

You pay for that luxury with a slightly mediocre audio experience. But when you are basking in the silence that envelops you with the QC25 on your head, in your own private world where nothing can disturb you, you’ll put up with an average sound. Besides, I don’t know about you but I listen to music on an iPhone, not a $1000 CD player.

But if you listen to music in a quiet place and want audiophile quality headphones, then don’t waste your money on the Bose QuietComfort 25. They’re not for you.
