The Liberty Air 2 Pro charging case is also radically different to the Liberty Air 2, which has an upright style charging case; whereas the Liberty Air 2 Pro has the same pebble-shaped, bathtub style charging case as the Liberty 2 Pro, which makes removing the earbuds easier. The charging case opens flat horizontally, in a similar way to a sliding sunroof of a car. 
The Liberty Air 2 Pro sliding mechanism works just as smoothly and can be easily operated with a few fingers of one hand and without slipping, thanks to the rubbery coat across the charging case. The Liberty Air 2 Pro charging case uses a similar friction hinge mechanism, which allows you to leave the lid open ajar . This is particularly useful after a sweaty session to allow the earbuds to air dry safely inside the charging case without having the charging case lid open all the way.
The Liberty Air 2 Pro charging case doesn't have a rubber cap, which is always useful to prevent pocket lint ingress. The charging case takes 2 hours to re-charge via USB-C cable and 2.5 hours via a 10W qi-certified wireless charging pad. There is a status led on the earbuds but, it does not blink during audio playback. The Liberty Air 2 Pro have a similar low IPX4 rating as the Liberty 2 Pro. The Liberty Air 2 Pro also integrates two extra microphones for calls, bringing the total to a whopping six noise cancelling microphones, which do a good job of naturally amplifying your voice over the background noise without distorting.
The Liberty Air 2 Pro earbuds also feature touch sensitive controls, each having a double tap function and a hold function for controlling a total of four functions. Volume is not supported by default but, it can be enabled from the Soundcore app, although at the expense of another function. There is also automatic play/pause, which can be enabled or disabled via the app. 
Auto play/pause works well, activating when the earbud is removed from the ears and without triggering when tilting the head at an angle. There is no voice prompt when toggling between ANC modes. Thanks to app support, the Liberty Air 2 Pro "bassy"sound signature can be altered to your liking by selecting one of the presets or by manually tweaking the sound via the 8-band equalizer
At 52 grams (charging case) and 6 grams (earbuds), the Liberty Air 2 Pro earbuds and charging case are heavier than the Liberty Air 2 but lighter than the Liberty 2 Pro. The Liberty Air 2 Pro charging case has a squarish design, measuring 6cm long and 6cm wide. The height of the charging case is 2.5cm high.
The Liberty Air 2 Pro come with nine pairs of bowl shaped silicone eartips of various sizes, including XXXS ear tips for really small ear canals. Thanks to the generous assortment of sizes and the thinness of the silicone, the Liberty Air 2 Pro are guaranteed to fit comfortably inside the ear canal and stay in, thanks to the rubbery coating. The fit is secure, although not as secure in the ear as the Liberty 2 Pro, which integrates wingtips. The ear tips come nicely organized inside a plastic retainer, although the retainer cannot be removed like you can with the Liberty Pro 2 ear tip organizer. An unbranded charging cable is also included. You can buy the Soundcore Liberty Air 2 Pro from amazon. Check out the review of the new Soundcore Life P3 hybrid ANC earbuds
