Sound quality is pretty good though at first it felt a little airy between the two drivers(10.5mm bass driver and a 4.6 titanium coated tweeter) which give it amazing sound especially with LDAC. Just EQ it and it sounds good/not as airy as before. Case screen isn't important btw

The verdict
The Anker Soundcore Liberty 4 Pro are excellent wireless earbuds. They sound good, have good noise canceling, and are absolutely packed full of features. At a starting price less than half that of top competitors, the Liberty 4 Pro are an easy recommmendation.
✓Liked: Great companion app, Good sound quality, Good noise canceling, Bluetooth 5.3 with LDAC
✕Could be better: Charging case is a bit of a gimmick, Case is a fingerprint magnet, Spatial audio performance is poor
