I recently released a top 5 guide of the best noise cancelling headphones for 2019.  The Sony WH1000XM3 currently tops that list and just dropped in price by $50: see at amazon.com. Hidden among the ANC sequoias of the guide is a noise cancelling gem called the WH-CH700N. It has been mentioned by other critics that Sony may need to create more user-friendly model nomenclature (I might agree).  Regardless of the (model) name it does live up to the standards of what most expect from Sony: High Quality (overall) coupled with a wide range of pricing associated to various models.

The Sony WH-CH700N has a lot going for it. Comfortable padding (I believe faux leather) on the headband (with adjustable slider) and earpads. Solid array of buttons including noise cancelling/voice assistant button, power button, pause/play, next track/previous track, and volume up/volume down. Foldable swivel design that folds “flat” to facilitate storage. Quick charge (via usb) that lasts up to 35hrs (more than WH-1000XM3). Comes with an audio cable for up to 50hrs of wired used. Voice assistant (google, alexa) to be utilized with the built-in microphone. Active noise cancellation that is effective and noticeable.

Additionally, the Sony WH-CH700N may be interpreted as the “Goldilocks” of noise cancelling headphones. They’re stylish, yet do not scream look at me. They’re comfortable and customizable to a degree of “just right”. They produce HQ sound that delivers the treble and some bass without being overpowering. The price is fitting for quality, but still does not break your bank account. Lastly they provide an intangible… a perception of high quality that is generally universally accepted as not too much or too little.

I encourage you to take a look at the Sony WH-CH700N on amazon.com and see for yourself the specs, features, and price and determine if they’re “just right”.

Wireless: Yes (can be wired)
Enclosure: Closed-back

Active noise control (ANC), also known as noise cancellation, or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first.

Noise Cancellation Process

Further Explanation

Sound is a pressure wave, which consists of alternating periods of compression and rarefaction. A noise-cancellation speaker emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out – an effect which is called destructive interference.

Modern active noise control is generally achieved through the use of analog circuits or digital signal processing. Adaptive algorithms are designed to analyze the waveform of the background aural or nonaural noise, then based on the specific algorithm generate a signal that will either phase shift or invert the polarity of the original signal. This inverted signal (in antiphase) is then amplified and a transducer creates a sound wave directly proportional to the amplitude of the original waveform, creating destructive interference. This effectively reduces the volume of the perceivable noise.

A noise-cancellation speaker may be co-located with the sound source to be attenuated. In this case it must have the same audio power level as the source of the unwanted sound. Alternatively, the transducer emitting the cancellation signal may be located at the location where sound attenuation is wanted (e.g. the user’s ear). This requires a much lower power level for cancellation but is effective only for a single user. Noise cancellation at other locations is more difficult as the three-dimensional wavefronts of the unwanted sound and the cancellation signal could match and create alternating zones of constructive and destructive interference, reducing noise in some spots while doubling noise in others. In small enclosed spaces (e.g. the passenger compartment of a car) global noise reduction can be achieved via multiple speakers and feedback microphones, and measurement of the modal responses of the enclosure.

Active vs. Passive Noise Control

Noise control is an active or passive means of reducing sound emissions, often for personal comfort, environmental considerations or legal compliance. Active noise control is sound reduction using a power source. Passive noise control is sound reduction by noise-isolating materials such as insulation, sound-absorbing tiles, or a muffler rather than a power source.

Active noise canceling is best suited for low frequencies. For higher frequencies, the spacing requirements for free space and zone of silence techniques become prohibitive. In acoustic cavity and duct based systems, the number of nodes grows rapidly with increasing frequency, which quickly makes active noise control techniques unmanageable. Passive treatments become more effective at higher frequencies and often provide an adequate solution without the need for active control.
