The Bose Noise Cancelling Headphones 700 has a more modern and unique design that is iconic and stand out a lot. The headband of the Noise Cancelling Headphones 700 is covered with silicone while the WH-1000XM3 has plush cushions. The ear cushions on both models are also much large enough to encase your ears. The weight of the Bose equivalent to the Sony's. From my experience, I can wear both of them all day without fatigue. They do manage to keep their low-profile look. with mostly plastic, it is worth noting that the headband is built with metal. Overall, the BOSE NOISE-CANCELLING HEADPHONES 700 wins this round.
Moving on to comfort, both Bose and Sony improved the size of the earcup cushions so that they encase your ears and not cause any wearing fatigue. Hence, users will be able to wear it for long flights. The clamping force of the Bose's is slightly stronger than Sony's. Both headphones never add any pressure to the crown of the head or to the jawline even after long hours of wearing them. Hence, the round is a TIE.
Next, Sound Quality. In my opinion, I find that the sound of the Bose Noise Cancelling Headphones 700 & Sony WH-1000XM3 is fantastic for all genres of music. Those who like to tune their sound should look at the Sony WH-1000XM3 as Sony allows users to do so with selected presets and customisation with the Headphones Connect app, available for download on the App Store and Play Store, The bass response on the Sony's are deeper and clarity of details and instruments are more articulate due to the support for LDAC and AptX HD codecs with a compatible device. The Bose's do a great job as well even though the sound on the Bose is auto-tuned for the user. There is a great emphasis on the mid-range with the Bose Noise Cancelling Headphones 700, where vocals are heard. All in all, the SONY WH-1000XM3 wins this round.
Moving on to the most important part, Noise-Cancelling. From my test, the Sony WH-1000XM3 managed to successfully beat the Bose Noise Cancelling Headphones 700 by a little. Sony's feature Adaptive Sound Control allows for toggling of different noise-cancelling modes like Walking, Staying, Transport and Running. Each has different levels of noise-cancelling and ambient sound mode. These are all automatically detected by the headphone itself. Users can toggle the amount of ambient sound let in, focus on voice only or just turn it off completely. Atmospheric Pressure Optimizing is another feature that helps to optimize the noise-cancelling to fit different environments such as in an aeroplane or on the ground. In the end, these features managed to defeat the noise-cancelling abilities of the Bose which only allows for a fixed ambient sound mode through its levels 0 to 10 adjustments. So, the SONY WH-1000XM3 wins this round again.
In the portability category, I find that the Sony’s does better as it folds up into a much more compact profile for easy storage. They both come with a hard-shell carrying case to protect the headphones and a spot to store all your cables. However, this time the Bose do not fold up, instead they fold flat, hence taking u much more storage space. This round goes to the SONY WH-1000XM3.
Both the Bose's and Sony's have their own features. Sony offers an app called Sony | Headphones Connect while Bose offers the Bose Connect App. Both are available for download on the App Store and Play Store. Sony's App allows users to take full control of the sound setting and Noise-Cancelling function while the Bose App allows for changing of Noise-Cancelling intensity. There are buttons on the headphones themselves to cycle through different noise-cancelling modes as well. Moving on to wireless usage, with both headphones I experience absolutely no Bluetooth drop-outs or hiccups. The cable of both headphones does not have any inline controls or mic. Hence, playback controls or answering of calls is unavailable. The Bose uses a 2.5mm to 3.5mm which makes it harder to replace when lost instead of a 3.5mm to 3.5mm which the Sony uses. The 30-hour battery life on the Sony WH-1000XM3 in wireless mode with noise-cancelling also beats the 20-hour battery life on the Bose Noise-Cancelling Headphones 700. Both headphones do charge via USB-C. Overall, the Connectivity category goes to the SONY WH-1000XM3.
THE BOTTOM LINE
Overall, the SONY WH-1000XM3 managed to beat the Bose Noise Cancelling Headphones 700. In terms of sound quality, battery life, noise-cancelling and connectivity, Sony exceeds expectations.
