Bose has become the go-to brand for keeping people entertained with headphones on long-haul flights. Just look around yourself next time you're on a plane and you'll be rewarded with the site of dozens of the company's flagship Bose QuietComfort 25 sitting atop people's heads.
But the QuietComfort 25 came out in 2014, making them a whole 4 years old now. Since then we've seen an explosion in the amount of wireless headphones on the market, which means it's finally time for Bose to join the wireless revolution.
The QuietComfort 35 headphones mark the first time that Bose has brought its iconic noise-cancelling headphones into the wireless space, and what's surprising is the audio brand has managed to do this with very little compromises.
Very handily, battery life has improved to the extent that you don't constantly have to worry about your headphones running out of juice midway through a flight. What's more, technologies like NFC have made the process of pairing your phone and your headphones as easy as just tapping one on the other.
If you need more features - like a built-in voice assistant - you can jump over to the brand-new Bose QuietComfort 35 II, which offer everything you see here plus some new bells and whistles. But, if you like your smart assistants confined to your phone and smart speaker, the original QuietComfort 35 remains one of the best noise-cancelling headphones on the market, bar none.
Anyone who's ever laid eyes on Bose's QuietComfort 25s will find the 35s instantly familiar. The simple design of their oval earcups might not be the most exciting on the market, but I personally prefer them to some of the more 'fashionable' efforts of Bose's competitors.
The headphones are available in black or silver, and on each earcup is a Bose logo which although raised slightly doesn't draw too much attention.
The headband connecting the two earcups is well padded, and the way the headphones sit on your head is very comfortable overall. Partly this is because their weight is nicely distributed, but it's also partly because of the quality of the cushioning on the cups. I have personally worn these headphones for hours at a time and have found them to be comfortable throughout.
On the left earcup is a single 2.5mm jack for connecting the wired connection to your device, but in order to get the most out of the QC35s your attention should instead be focused on the right earcup where you'll find a power slider, micro USB charging port, and buttons for pausing, skipping, raising and lowering the volume (which work with both iOS and Android unlike the QC25s).
Pairing the QC35s was a breeze. You slide the power slider all the way to the right to put the headphones in pairing mode, and then you simply select them from your phone or laptop's Bluetooth menu.
Alternatively if your phone is one of the increasing amounts of Android phones that support NFC pairing then you can connect your headphones by simply putting them in pairing mode and tapping the rear of your phone against them.
The headphones are very good at switching between multiple connections. I had my pair of QC35s connected to both my laptop and my phone, and the headphones had no trouble switching between the two as I played music alternately from both devices.
Battery life on the QC35s is very good. Bose promises that the headphones will last 20 hours when operating wirelessly, which rises to 40 hours when used as a pair of wired headphones. I didn't time exactly how long the battery took to run down, but the headphones lasted me several days of on and off use before needing to be recharged.
It's a minor point, but whenever you turn the headphones on they helpfully play a short audio notification of both the device they're connected to as well as how much battery life is left. It rounds this to the closest 10%, but it's still a helpful indicator to have.
Finally these headphones do include a mic which allows them to be used as a headset for making phone calls and the same noise-cancelling technology is used on the mic to eliminate background noise.
When it comes to Bluetooth music streaming there's standard Bluetooth and then there's AptX Bluetooth. The latter is appreciably better for streaming music, but Apple's devices only support the former. You can read more about the difference between them in our Bluetooth vs AptX explainer.
When I asked a spokesperson from Bose about the lack of support their response was that the company felt the quality offered by standard Bluetooth was good enough, but it's nevertheless a shame not to see high-fidelity audio properly supported.
The good news is that in spite of the lack of AptX support the QC35's wireless performance doesn't feel lacking in the slightest. Their sound is lovely and crisp, and there's none of the flatness that you can get with wireless headphones.
The soundstage on these headphones is phenomenally broad, and when paired with a high-quality recording such as Massive Attack's Unfinished Symphony it's very easy to feel immersed in the sound.
Switch to a track with a bit more speed like Uncombed Hair by Yung and you'll notice just how much punch the QC35s have in their bass, which adds a good amount to the rhythm of the song.
I wasn't completely sold on the Active EQ features of the headphones which boosts the bass frequencies slightly as you lower the volume to compensate for how lower volumes tend to bias higher frequencies.
In my subjective tests this effect often ended up making the tracks feel ever so slightly too bassy at lower frequencies.
But the real star of the show when it comes to Bose's QuietComfort range is the noise cancelling, and I'm happy to say the QC35's are as good as ever.
As with all noise-cancelling headphones, the QC35's are best at cancelling out consistent low frequencies like the rumble of a train or plane rather than higher-pitched office chatter, but even the latter is drowned out to a certain extent by the padding around the headphone's earcups.
The noise-cancelling sensation is a little odd at first and feels a little like being in a pressurised cabin, but you soon get used to actually being able to listen to your music rather than the world around you.
It's also strange using the headphones when they're cancelling out the noise around you (including your own voice), but the microphone works very well despite not being located on a cable closer to your mouth like most wired headphones.
I used the headphones for a half hour video call in a noisy office and was perfectly audible throughout thanks to the efforts of the noise-cancelling technology.
The Bose QuietComfort 35s offer great sound quality and the best noise cancelling out of any headphones I've tried. They're super comfortable, and despite the fact that they don't use the newer AptX Bluetooth standard the wireless doesn't harm their sound quality one bit.
The Active EQ is subtle, but personally I don't think it added anything to my listening experience.
The best noise-cancelling headphones just went wireless, and you won't miss the annoying tangled cable one bit. The Bose QuietComfort 35 headphones sound every bit as good as their wired brethren, and offer all of the convenience of wireless headphones with none of the drawbacks that used to plague them.
