It gets worse when you turn or tilt your head, which creates larger gaps that let outside sound in. To top it off, the active noise canceling feature itself isn’t particularly effective even under best-case scenarios. You get a fairly basic background noise suppression, which feels somewhat timid and underwhelming, even compared to rivals in this price range. When combined, it creates one of the least effective noise canceling effect I have tested. It’s very dependent on your head shape and position, and slight shifts can cause a change in the background noise levels.

Of course, any noise cancellation is better than no noise cancellation, and even at its worse, the CH700N are still a lot quieter than a standard pair of headphones and I’d pick these over standard headphones for a plane ride any day. However, considering noise cancellation is the big feature of these headphones, they don’t seem to be all that good at them. A small observation here; turning the noise canceling on or off is a somewhat lengthy process. Turning it off incurs a 3.7 seconds pause while turning it back on takes 4.5 seconds. During this time you can’t hear your music playing in the background.

While it’s unlikely you will be switching noise canceling back and forth, in case you do you will have to do a fair bit of waiting. Software The CH700N work with Sony’s Headphone Connect app, available on both, iOS and Android. This app enables additional features for the headphones, such as surround sound effects and equalizer. You can also enable or disable the noise canceling feature from here, switch Sony’s DSEE feature, which claims to restore lost detail on compressed music and change the functionality of the NC button on the headphones from switching noise canceling to invoking Google Assistant. Sony Headphones Connect The app will also show you the battery level and the codec you are using currently, although that information can be found in the Bluetooth settings of most recent Android phones as well.

As we noted in the 1000XM3 review, the app lets you change the codec from SBC to whichever is the highest quality codec the headphone supports, which in this case is aptX HD. The moment you do that, you can no longer use the surround sound and equalizer features found within the app. These only work with the SBC codec. I personally never use these features and couldn’t care less that they weren’t available with aptX HD but if you do then you should know you are losing out a bit on the audio quality front by having to switch to SBC to use them. The app is also responsible for upgrading the firmware on the headphones, although no update was released during my testing.



Battery Life Battery life is always a concern when switching to wireless headphones. You now have yet another device to charge and there is always the anxiety that your headphones might die, especially during long flights. With the CH700N, however, Sony has solved at least one of those issues.

The headphones have a claimed battery life of a staggering 35 hours with NC on, and 40 hours with it off. That’s more than any other headphone in this price range, or even more than many more expensive headphones. If you are a frequent flier, you can pretty much get through even the longest flights in the world on a single charge. I didn’t quite get around to verifying Sony’s lofty claims but in the three days I’ve been using these headphones, the battery went from 70% that it had from the factory to just 50%. This is with about 3-4 hours of use every day. I think it’s fair to say that Sony’s claim is legitimate but if I ever get the time or muster the patience, I’ll properly test the claim and update the article.



What’s a bit of a downer on the battery life is the charging time. While a ten-minute charge is supposed to give you 60 minutes of battery life, a full 0-100% charge takes a massive 7 hours.
