Last but not least, the connectivity of these 3 earbuds. Starting off with the Apple Airpods Pro, there is no official app but they do work on both Android and IOS. On IOS, they connect instantaneously but on the Android side, you have to go into Bluetooth settings to connect them. Basic play/pause and switch between Noise-cancelling and Transparency Mode works too, you will only lose the ability to call up Siri for smart assistant support. You can fiddle and change the control scheme on IOS, update the firmware, check the battery life and do an ear fit test to ensure that you have a good seal. Next, the Sennheiser’s have a decently well curated app. In the app, you will first see the Transparent Hearing setting which allows you to hear your ambient surrounding sound so you can always hear the next train announcement or traffic noise to stay safe. You can choose to mute audio or continue playing music with Transparency Mode on, however you cannot control the amount of noise you want to let in. If you prefer the faster way of removing one earbud to hear someone, the earbuds will automatically pause your music, and that you may turn off if you don't want it enabled. Next, you will find the Sound Equaliser which you can choose to customise your very own. This time, you can save presets and switch between them seamlessly. If you are looking for the cleanest sound signature, leaving the equaliser on Neutral will do the job. Moving on, you can also enable or disable Smart Pause, Active Noise-Cancelling, Auto Accept Calls, or SideTone update the earbuds firmware, change your voice assistant or change to use either voice or tones prompts. If you ever lose your earbuds, you cannot trace them back since they do not have Tile integration like the Momentum 3 Wireless Headphones. It is by far a very comprehensive app until you use the Sony’s app. In the app, you will first see the battery life status of both earbuds as well as the case charge on the top. Next, there is the Status settings, which has the music player controls to enable you to play/pause or skip forward and backwards right in the app itself. You can also adjust the volume levels. Adaptive Sound Control is also available to allows for toggling of different noise-cancelling modes like Walking, Staying, Transport and Running. Each has different levels of noise-cancelling and ambient sound modes. These are all automatically detected by the headphone itself through its smart Sense Engine technology built in. Now, the function has evolved to recognize the location you have been to and automatically tuned the settings when you are in that location. Of course, users can toggle the amount of ambient sound let in, focus on voice only or just turn it off completely. There is also a quick attention mode which allows users to strike up a quick conversation with someone without removing the earbuds from their ears. In the Sound settings, you are first greeted with the equaliser option where you can choose from the presets or customise your very own. You can save up to 3 presets and switch between them seamlessly. Moving on, there is the 360 Reality Audio, Sony’s object-based spatial audio technology that enables users to be immersed in music as intended by artists. However, this feature is currently only available to users of Deezer, nugs.net and TIDAL. There is no support for mainstream music streaming platforms like Spotify, Apple Music or YouTube Premium as of yet. The app will bring you through the set-up process of scanning your ear and face shape to determine and fine tune the music. You can also switch the Sound Quality Mode to put a Priority on Sound Quality or Stable Connection and enable or disable DSEE HX. Lastly, we have the System settings, where you can choose to enable or disable auto-pause upon removal of earbuds from your ears. You can also customise the buttons function scheme to your most used settings so you don’t have to take out your phone to control the earbuds themselves. There is also automatic power on/off to help you conserve battery life in case you forget to turn it off. Lastly, you can also change the language of notifications and voice guidance and enable or disable automatic download of software. There is also a quick attention mode which allows users strike up a quick conversation with someone without removing the earbuds from their ears. On Bluetooth connection, the Airpods Pro features Class 1 Bluetooth and the AAC codec while the Sony’s feature Bluetooth 5.0 with SBC and AAC codecs. Meanwhile, the Sennheiser support AptX Low-Latency, AptX, AAC and SBC codecs together with Version 5.1. So definitely high-quality audio codecs support with the latest Bluetooth standards. Both the Airpods Pro and the Sony WF-1000XM3 allows for listening with one ear with either bud but the Sennheiser’s only support the right earbud single ear listening. Comparing battery life, the Sennheiser lasts the longest with 7 hours on a single charge, the Sony’s second with 6 hours and the Airpods Pro with 4.5 hours. The Sennheiser’s case also holds the most charge with a total of 28 hours, while the Apple and Sony’s case with 24 hours.
