Noise Cancelling Technology

Our hearing organ is very important since we can both enjoy songs, listening and accepting information, as well as understand what message to give the proper response. Noise is anywhere from the sound of your fingers tapping a keyboard, the air conditioner’s fan, the microwave noise, the sound of your coworkers coughing and sneezing, even the sound of our own breath. These are what we hear on the daily but, depending on where you are at, the level of distracting noise can be more apparent and annoying.

Moreover if you live in a crowded metropolitan area, it feels like the city never sleeps while our body craves to rest properly. This is when noise cancelling technology comes in handy and as the name suggests, the device with noise cancellation will “cancel” ambient noise and let you rest better, enjoy a quieter environment or the music playing in your listening device. The theory is to counter the noise with the listening device to produce a quieter impression.

Sound is just compression and decompression of the particles in a medium or air if we are talking about sound that we heard on the daily. Our listening device, for example headphones, is able to cancel the sound because they use an “anti-phase” concept. It is said that if you are taking two identical waves and placing them on top of each other by matching up the peaks and throughs, these waves will be “in-phase” that results in a larger sound.

But, if you are going to delay one of the waves by exactly one half wavelength to match up the throughs with the peaks of the other, these waves will be called as “out of phase” and subtract from one another since the positive pressured of one of them is acting against the negative pressure of the other or vice versa. It is like adding one and subtracting one so we are left with none. This is very complicated but also the basics of noise cancelling technology which is often found in headphones and earphones.

To make this happen, headphones have to use a microphone on the outside. As the device listens to the ambient noise around you, then the processor will work it from here. The headphone is utilizing this mechanism to create sound that is exactly the opposite from what it hears so then the system can cancel it out. This way, ambient noise in the environment will be blocked not only by the headphone/earphone sealing but also the technology.

About Bose QC35 II and 700

If you are here then we assume that you are also looking for a device that can deliver the purpose and while noise cancelling was popularized by headphones, nowadays TWS are also coming with the capabilities, especially those from the high-end range. Depending on which fits within your lifestyle the most or which seems to work best in your daily life, we can choose any of them. But, in comparison the headphone is usually better, moreover they have a more robust passive sealing.

For those who want to get the best noise cancelling performance, Bose is one of the most prominent options you can find in the market. This brand is very well-known for the audio products and there are plenty to choose from this company as well. We are sure most people are familiar with this name already and if you are aiming for the best performing headphone with noise cancelling, make sure that they are also working well in the type of activity you will be wearing them.

As one of the prominent players in the market, this brand carries so many noise cancelling headphones in which many are among the best options too such as the extremely popular Bose QC35 II and 700. Both of them are not the same and in comparison the QC35 is an older offering from the brand as well yet, it is still a very promising choice, moreover when you compare the price point. Sony may have won the current noise cancelling headphone’s competition with their WH-1000XM4 but for those who prefer Bose’s sound these two are more promising.

In terms of overall quality, we agree with so many others that Bose 700 is a slightly better choice to QC35 II but, if you see the prominent price gap, it becomes arguably that the headphone is still best for everyone. When comparing the performance of noise cancelling and sound quality, the latter is not only sound good but also has a stronger noise cancellation function. Read also: Logitech G935 Vs 933 here.

Bose QC35 II and 700 Design

Before moving forward, let’s see what Bose QC35 II and 700 can offer from the physical point. In comparison the QC35 II is more traditional looking than the latter but it is also lighter so when worn for a few hours the headphone doesn’t stress your head or neck as much. The other difference is build quality because even though none of them are fragile, we do think the flex produced by Bose 700 sometimes can be quite concerning compared to the QC35 II.

As for the on board control, the two are about the same and minimalistic. Being wireless headphones they are very compact already with Bose 700 having two buttons on the right for power, Bluetooth, and muting while on the other ear cup we have a button for ANC and talk through. What’s interesting is this headphone also has a touch-sensitive surface on the right earcup for controlling calls and music. With QC35 II you can have all of the basic controls and for some people the feeling of these buttons probably gives better tactile experience as well.

Bose QC35 II and 700 Sound Quality

Now for the most important point, let’s listen to the Bose QC35 II and 700 first. In comparison, we are not sure why the experience across users with Bose 700 is not as even as the QC35 II but the bass performance is better with this headphone with just a slight margin. None of them are bad at all, if anything they sound really good and suitable for bass heavy music. The mid area for both are excellent and you can definitely hear the lead instruments are present in the mix.

What’s surprising is while the Bose 700 is in general better in both bass and mid-range, it is not as good on the treble. In QC35 II, the treble is very accurate and balanced so we can hear many details on the vocals and instruments but when it comes to QC35 II, especially on the mid-treble, the bright instruments don’t sound as airy and somehow sound dull.

Bose QC35 II and 700 Noise Cancelling

Next for the sound cancelling performance, the Bose QC35 II and 700 are amazing and among the best you can find in the market. They can block low frequencies really well but you may have to try a few settings and adjustments before finding the best setup that matches with your preference. The two are really helpful when it comes to making the environment less noisy, such as when you need to concentrate while working in a coffee shop or enjoying your music without the rumble of the engine getting in the way of the experience.

What we found better is the passive sealing of Bose 700, probably because it feels slightly tighter. We do think this headphone is covering the ears and sound coming from the driver more effectively than QC35 II as you crank up the volume. With the QC35 II some people sitting near you may hear a whispery sound leaking from the headphone but not with the new headphone.

Bose QC35 II and 700 Comfort

Lastly on the overall experience and comfort, the Bose QC35 II and 700 are very comfortable for prolonged use depending whether you are used to it or not because when new they are equally tighter on the head. QC35 II causes worse leakage because it is light and the clamping force is about half of what Bose 700 produce yet this is also the comfier headphone in comparison. The 700 do have a touch sensitive surface which improves the user experience however.

Bose QC35 II Vs 700

Both Bose QC35 II and 700 are great options if you are in the market for a noise cancelling headphone. We are not sure whether the internal technology is improved in Bose 700 but it sure has better sealing that can help with noise isolation and helps when it comes to covering the ears from outside noise. What’s better in QC35 II is the treble and comfort which makes the headphone in general not an inferior alternative at all.
