Apple’s AirPods Pro 2 are the first noise-cancelling headphones I’ve ever tried. And they’ve ruined my old headphones.
Even though noise-cancelling headphones have been around for a while, I was content to stick with my old, perfectly adequate headphones. They do the job they were made to do, and as the truism goes: “You can’t miss what you’ve never had.”
That was until this past weekend, when I came into possession of the Apple AirPods Pro 2 noise-cancelling headphones.
Whenever I’ve used technology, I’ve always been mindful of trying to make it last as long as possible. Partly because I hate wasting money, and partly because I hate the idea of creating yet more environmental waste. But every now and then, there are technological leaps forward that really do justify making that new purchase. And for me, noise-cancelling headphones are the latest example.
Noise-cancelling headphones manage to reduce the amount of ambient noise that you hear while you’re wearing them. If, like me, you’re someone who likes listening to music, podcasts or audiobooks when you’re out for a walk, you may be familiar with those moments when traffic noise (among other things) makes it virtually impossible to hear what you're listening to, without turning the sound all the way up to 11 – which isn’t ideal. After all, studies have shown that prolonged exposure to loud noises is bad for our hearing.
By using noise-cancelling headphones, we can reduce both the volume of the external noises we are exposed to, such as traffic and roadworks, and in turn, keep the volume down on whatever we are listening to, without compromising the ability to hear what’s going on.
"Noise-cancelling headphones mean I can now thoroughly enjoy the sound of silence."
While I’d love to imagine that a tiny imp is holding an even tinier pillow against your ear whenever a loud noise presents itself, the reality is more practical. There are two types of noise-cancelling headphones: passive (sometimes known as PNC); and active (ANC). PNC devices physically soundproof your ears and this type is common in over-ear headphones, which have a cup to cover your ear. ANC headphones are a more recent technology and is what we’re primarily talking about. According to Sony:
“[Active] Noise-cancelling audio devices use a built-in microphone to analyse the ambient sound waves around you and generate the opposite sound waves to reduce surrounding sound.”
In simple terms, the microphones on your headphones detect the external noise, and immediately generate opposing sound waves to neutralise (or reduce) what’s heading your way, in a process known as phase cancellation.
This is most effective for sounds in the low to medium pitch range. So sounds such as traffic, trains and aeroplane noise will be greatly reduced (although not totally blocked).
Many of the best noise-cancelling headphones, including the Apple AirPods Pro 2, or Sony's WF-1000XM5, use adaptive noise cancellation. This feature automatically adjusts the level of noise cancellation to suit the level of ambient noise in your surroundings. Overall, this will offer a better experience compared to a set that don't have this feature.
Noise-cancelling headphones will also offer some form of transparency mode, that allows you to be more aware of your environment when it suits you. Happily, this isn't exclusive to premium devices either, and many cheaper models (including Sony's WF-C700N) will also offer features of this sort.

There are plenty of benefits to using noise-cancelling headphones, but there are a few potential drawbacks to be aware of as well.
Given the vast benefits of walking, I enjoy going out for a regular stroll. Usually, I’ll head out and listen to an audiobook or podcast. My old headphones were generally adequate if I was out walking somewhere quiet.
But I did notice that as soon as I walked anywhere that was busy, or if traffic passed me, it became extremely hard to hear what I was listening to. In some cases, for example when a bus or lorry was driving by, I would have to consider turning the volume up to maximum to be able to hear anything other than road noise. And as we
I’ve already mentioned, that's not good for your hearing.
I was keen to try the Apple AirPods Pro 2 when I got the opportunity. And in summary, they did not disappoint. From the moment I put them in my ears for the first time, it was like being cocooned in a bubble of quiet. Everything was noticeably clearer, and I have never had to turn the volume up beyond about half on my phone to hear my podcasts.
This was regardless of the setting. I’ve had HGVs, buses, and even an overly enthusiastic Porsche driver going past me, without needing to massively increase the volume. Traffic noise is reduced to little more than a whooshing sound that resembles the sound of the sea – a far more pleasant experience than a loud engine.
That’s not to say that the world was silent. While I did make sure to follow the Green Cross Code every time I crossed a road, I was still aware of vehicles and the outside world. Everything just felt a little further away, and a little less intrusive. For me, noise-cancelling headphones have been a revelation.
As I wrote earlier, you don’t miss what you’ve never had. But now that I’ve experienced the difference high-quality noise-cancelling headphones make, I know I’ve crossed the Rubicon. There's no going back. Noise-cancelling headphones mean I can now thoroughly enjoy the sound of silence.
