No wires, no distractions, just music

After that, the balance is really quite even. There is emphasis put on the bass frequencies, but not enough to say it is inherently skewed. Moreover, Sony has managed to keep the low end relatively taut, while also providing plenty of punch, to avoid it sounding lazy.

The WH-CH700N Wireless Noise Cancelling Headphones are made for long listening on the move. One Push Artificial Intelligence Noise Cancelling (AINC) adjusts to your environment, so you can eliminate unwanted noise as you travel.

Freedom from noise and wires
Listen without wires and block out unwanted background noise, just hear your favourite music with digital noise cancellation.

Noise cancelling made for travel with One Push
Artificial Intelligence Noise Cancellation (AINC) analyses background sound and adjusts it for optimal performance on aeroplanes and other noisy environments. Just press and hold the NC button on your headphones to activate it.

NFC™ One-touch for instant connectivity
Near Field Communication (NFC™) technology makes complex set-up sequences a thing of the past. Simply touch selected NFC™-enabled devices to the on-body N-mark for a quick, seamless connection, then start streaming content via Bluetooth® connection. No NFC™? No problem. You can still manually connect using your device’s settings menu.

Listen all day, charge up quickly
Keep your music playing all day. A built-in Li-ion battery delivers up to 35 hours of power (depending on your music settings) and is rechargeable via USB. Quick Charging gives 60 mins of play back from 10 minutes of charge.

Hear it all with 40mm drivers
Get more from your music thanks to 40mm dome drivers that deliver deep bass and a wide frequency range.

DSEE restores detail to your digital music
Boost the quality of your compressed music files. When an original music source is compressed, it loses the high-frequency elements that add detail and richness to your favourite tracks. The Digital Sound Enhancement Engine (DSEE) faithfully restores these to produce a high-quality sound that’s closer to the original recording.

Tune your headphones to your perfect sound with the free Sony | Headphones Connect App for Android and iOS. Adjust audio levels and digital soundfield modes with a range of presets and customisable EQ settings easily from your smartphone. Virtualphones Technology (VPT) simulates outdoor-stage, club, hall, or arena style sound.

The best headphones in my collection
I tried this headphones before buying them. I went to a big store and had the opportunity to test a few Bose, Beats, skulls and a couple of other Sony. I wasn’t planning to buy anything because I already have 8 different headphones at home but... I tried them on and got this Wow feeling. To be honest I wasn’t expecting them to sound this good. I have a really good set of headphones (Senheisser 700 with a DAC and headphone amp connected to my computer) but somehow this pair of Sony just delivered the right sound out of the box. The reason I wasn’t expecting a great sound is that they are wireless and in theory you just can’t get the same sound, there is a loss in quality and this is a fact but...
I use them with my phone and even though some people complain about the app I believe that they are critical to the experience. After a few minutes tweaking it, I got my perfect sound.
Like I said before, I tested a few others, including the most expensive Sony and a few others but this one was the right one for me.
You might have a different taste or you might listen to different genres and picking headphones is just a very subjective experience but I could not be happier. Since I got them they are my first option and I feel a little disappointment with the rest of my collection right now.
About the sound:
Clear, they are amazingly clear. If you like to hear all the instruments you are going to enjoy them.
Space, they have enough spacious to feel the separation and the soundstage is pretty good for the price
Bass, if you like it, they have it.
Comfort: very very comfortable. They are light and you might forget that you are wearing them.
Pads: made of plastic. I start sweating after an hour.

Excellent sound quality with decent noise canceling
Sony WH-CH700N is a headphone for people who like accurate and clear sound reproduction. It doesn't artificially boost bass or treble. It simply provides a non manipulated sound with no sacrifices in high, mid or low frequency ranges. So it's perfect to use with a good equilizer. However it sounds cristal clear without an equilizer. Sony offers a great sound equilizer for Android and iOS that works with some of their headphones and this is one of them. So you literally can tailor-make the sound reproduction of this headphone based on your pfreference. In that sense these headphones behave like a Sennheiser at a fraction of the cost. If you want to buy these mostly for noise cancelation then you are better off looking elsewhere. They do a descent job at noise canceling but there are better choices out there for just this purpose although very few of them have the sound quility of these. So in sum, if you want a headphone with excellent sound and decent noise canceling then this a great option.

These are awesome
I wanted a pair of Bluetooth noise canceling headphones since I travel a lot and am on airplanes often. These were affordable and have by far exceeded my expectations. The sound is great and blocks out a lot. I have to make a conscious effort to pay attention when beverage service is happening otherwise I won't hear the flight attendants asking me if I'd like anything to drink. Oops. The battery life is incredible as well. I charged it once after initially receiving them and have not needed to recharge them yet even though I use these pretty frequently. There is also an app you can download to change the sound settings on the headphones. Overall, great product value!
