Sony WH-CH700N: AINC Enabled Headphone Review

Sony added a new pair to its noise-cancelling wireless headphones range by launching Sony WH-CH700N on December. Sony is ascending to the top level among the headphone brands in India, over the past few years. The Sony WH-CH700N wireless headphones are specially designed for long hours of music playback.

The headphones feature Sony’s Artificial Intelligence Noise Cancellation (AINC) technology. It’s an adaptive audio technology which analyses background noise to adjust performance with the surrounding environment. Traditionally, wireless noise cancelling headphones have been expensive but Sony is trying to change that conventionality with the new headphone pairs. So today we are going to see whether the pairs are worth or not.


The  Sony WH-CH700N comes in a square box which has a matte finish and also it has a retail tag on the top. On the front side of the box, we can see a picture of the headset, the brand name, the product name and small illustrations of main features.

On the back side also there is a description of the features. when unboxing the outer pack, we can see another black box. After opening the black box we can see our beautiful headphone there! The packaging consisted of Headphone, Instruction Manual, Operating Instruction, USB Cable, Aux Cable. The packaging does not contain a carrying pouch.

Design And Features

Actually, Sony has used this design in several of their other headphones. The majority part of the headphone is made up of good quality plastic. The top part of the headband is pleather and provided more padding as well. A metal slider on headband allows you to adjust the headphones to your perfect size. The materials used in this headphone offers a matte look for it.  They have some really nice soft, comfortable type of earpads I have ever felt.

The ear cups are spacious to accommodate my ears but not too deep. Inside the earcups, soft mesh fabric is placed over the drivers. Over long hours of listening, you will not gonna experience any discomfort with these ear cups. You feel very less internal pressure when you put on CH700N. The ear cups are swivel flat. But these pair is not much compatible. The headphone comes in three colour variants: Black, Blue, Grey.

The controlling buttons are arranged in the bottom part of both earcups. The buttons are really smooth. The left one has the power/pairing button, which can be pressed and held to turn the headphones on/off or turn on pairing mode. An NC button that can be used to turn on/off noise cancelling or to call up Google Assistant. A micro USB port for charging and an input jack for connecting AUX cable. We could also see an NFC sensor on the left earcup for quick pairing.

On the right ear cup, we have the volume up and down as well as play/pause and skip forward and skip backward toggle in order to playback the music. We can also use the play/pause button to pick up or cut the call.

Before we switch on the headphone for the very first time, we need to install the Sony Headphones Connect app for enabling some features like switching noise cancellation,  remapping the Google Assistant and many more. By using the connect app, pairing is faster and reliable. Virtualphones Technology (VPT) simulates outdoor stage, club, hall or arena style sound.

The headphone weighs 255g. It has 40mm dome drivers that deliver deep bass and a wide frequency range. It comes with a sensitivity of 97dB/mW and enables a frequency response between 7Hz to 20,000Hz. Also, there is an impedance rating of 20 Ohms.

The Sony WH-CH700N can be paired in two methods: Bluetooth v4.2 and NFC. It supports SBC, AAC, aptX, and aptX HD codecs. A  cable which can be removed in 1.2-metre length is also rolled up to enable music playback via a traditional 3.5mm jack.

One of the main features of the Sony WH-CH700N headphones come with one push Artificial Intelligence Noise Cancelling (AINC) that helps to eliminate unwanted noise.  Another feature is the Digital Sound Enhancement Engine (DSEE) to boost the quality of compressed music files. It loses the high-frequency elements that add detail and richness to your favourite tracks when an original music source is compressed.

Sound Experience

The sound is so spacious and punchy. It’s really a fun exciting headphone to listen to it because it does great across all genres. Even it is classical or pop the sound flows crystal clear. I used this headphone while watching a movie, the dialogues were crystal clear…mind blowing. But when I plugged the cable in 3.5mm jack, the audio has a touch of noise like muddy, indistinct, and unpleasant to hear.

Sony’s punchy and tight bass might be a huge selling point, I just love it because it’s not excessive or overbearing. Highs are spacious and detailed. The mids are a bit freezy crisp and lifted, but not to the point of sounding bad. Audiophiles might not enjoy this nature of the mids. The lows are really bouncy. They have a nice grip but aren’t too dry.

It’s really hard to find a good noise cancelling headphone in the market at this price range. These don’t cancel noises nearly as well as the Bose QC35 or Sony 1000x series. They can even drown out the noise in a rushy road. But still, they won’t completely silence the world outside. They can reduce a noisy background to a gentle one. It cannot give a deep noise cancellation, I think this is because of the structure of earcups. The earcups are large but not deep enough. There are small gaps left below your ears, that let outside noise in.

Call Quality

The Sony WH-CH700N is doing a good job on calls. Making phone calls via voice commands were responsive.   I made a few calls, I could say the audio quality of the call of both my side and the other side was excellent. But sometimes can hear little background noise if we are in the noisy environment.

The voice capturing ability of the microphone and the noise cancelling ability is appreciable compared to other products in this price range.

Battery Life

Sony claims that a single full charge, which will be expected to take about 7 hours will provide up to 35 hours of battery life with NC on and about 40 hrs with NC off. While a Quick Charge technology, which is touted to give an hour of playback time with just 10 minutes of charging, a full charge takes a huge time of 7 hours.

Furthermore, using the provided cable and 3.5 mm jack option, we can even extend the battery life to up to 50 hours. You have to use the same micro USB cable provided for charging the headphone. That is seriously a downside. Because I think USB-C cables are more compatible.


These headphones are great in that they offer decent noise cancellation for the price. Without any kind of doubt, you can choose WH-CH700N, if you really need the noise cancelling feature.

These headphones are deeply impressive, mostly because they are a challenge against two major issues faced by headphone users – being poor audio quality and short battery life. This could end up being a new success for Sony.
