Design

Both headphones are great for travelling due to their collapsible and foldable design.

The padding on the headband and earcups of the Marshall Monitor II ANC (left) are thicker than those on the Bose QC35 II (right).

As mentioned in our comparison of the Marshall Monitor II ANC vs Bose NC 700, another excellent Bose noise cancelling headphones, the Marshall headphones is built like a tank. It comes with a solid metal frame and sturdy earcup materials that are scratch resistant due to their leather grain texture. Weighing 320 grams, this is not exactly the most lightweight pair of headphones. However, its weight won’t be an issue since it comes with thick but soft padding on the headband and earcups, making it very comfortable.

The Bose QuietComfort 35 II, on the other hand, still has a solid build, but not as good as the Marshall headphones. It has a metal frame as well, but there are more plastic parts than metal, which is a bit disappointing since it is marketed as a premium product. Weighing 254 grams, this is a lightweight pair of headphones that is very comfortable to wear for extended periods. It has soft padding on the headband and earcups which contribute to its overall comfort.

On the Marshall Monitor II ANC are two buttons and a knob for playback functions. The two buttons are for its ANC on/off and other functions such as activating voice controls, switching EQ presets and more. On the left earcup of the Bose QC35 II are its power/Bluetooth switch and three buttons for playback and volume control. It also has a new action button that can be used as either a dedicated ANC button or to activate voice controls.

If you travel a lot, both headphones are suitable since they both have a collapsible and foldable design. They both come with carrying bags, with the Marshall Monitor II ANC having a canvas carrying bag and the Bose QuietComfort 35 II having a hard case.

ANC & Additional Features

When it comes to noise cancelling, the Bose QC35 II performs better.

Both the Marshall Monitor II ANC (image) and the Bose QC35 II have a foldable and collapsible design for easier storage.

On the topic of active noise cancellation, the Bose QC35 II is definitely the better pair of headphones. It is capable of cancelling low and mid frequency noise better. That said, the Marshall Monitor II ANC is no slouch, but when compared to the Bose QC35 II, it’s a bit lacking.

As far as connectivity goes, both headphones can be used wirelessly or connected to a device with a 3.5mm port. Marshall and Bose both included a 3.5mm cable inside the box, but if you happen to lose or damage it, you can use pretty much any 3.5mm cable that you can find. Both headphones didn’t have any sort of issue when it comes to their Bluetooth connection. There are no stuttering, audio lag or connection drops to speak of. Overall, they are very consistent and reliable.

Both headphones come with their own companion app to customize their control buttons and tweak various settings. With these apps, you can customize EQ settings, reassign control buttons and more. That said, the Bose Connect App provided a more user friendly experience and it has a better interface.

Sound

Both sound good, with the Marshall Monitor II ANC having a slightly better overall sound.

The Bose QuietComfort 35 II comes in silver, black and blue.

The Marshall Monitor II ANC only has support for SBC while the Bose QC35 II supports both SBC and AAC codecs. If you like listening to high-res tracks, you won’t be able to take full advantage of their increased quality with both of these headphones since they don’t have aptX support. Maybe in the future, with a firmware upgrade, they can, but for now, you’ll have to settle for SBC and/or AAC.

When it comes to sound quality, the Marshall Monitor II ANC has a tight and defined low frequency and an emphasis on the mids. The highs are not exaggerated so there is no sibilance and it is pleasant to the ear. Overall, we really like the sound of the Marshall Monitor II ANC.

As for the Bose QC35 II, it has a fairly neutral sound signature but with an emphasis on the low frequency. While it won’t satisfy bassheads, the bass on these headphones can be considered a bit exaggerated. The mids and the highs are on point though, and they are nice to listen to.

Battery Life

With its 30-hour playback time, the Marshall Monitor II ANC wins this round.

Both headphones come with an audio cable, USB charging cable and a carrying case.

In terms of battery life, the clear winner is the Marshall Monitor II ANC, with its 30-hour playback time. You’ll be able to use it for longer periods without worrying about running out of battery. To get a full charge on the Marshall Monitor II ANC, you need to charge it for 2 hours, with a quick charge function of 15 mins for 5 hours of battery life.

As for the Bose QC35 II, its battery can have a runtime of up to 20 hours, which is good enough, but definitely not better than the Marshall headphones. To charge its battery to full capacity, you need a little over 2 hours, which is almost the same as with the Marshall. However, its quick charge function of 15 minutes only gives you 2.5 hours of playback, which is just half of what the Marshall headphones offers.

Verdict

While both are great headphones, the Bose QuietComfort 35 II is our recommendation if your main reason for buying a pair of headphones is for its active noise cancellation.
