The Sony WF-1000XM3 uses 6mm neodymium dome drivers and DSEE HX digital sound enhancement engine. It does not have support for aptX or Sony’s own LDAC.
So what does all these means? Can a casual listener notice any difference? Honestly no. The music sounds clean and fresh. However, I find the need to switch the equalizer to the ‘Bright’ setting which works well for the genre of music that I listen to (mainly guitar and pianos).
Based on specifications, the Sony WF-1000XM3 wireless earphones last up to six (6) hours with ANC enabled and it goes all the way up to eight (8) hours when disabled. With the case providing another three (3) charges, the Sony WF-1000XM3 true wireless earphones can last you somewhere between 24 to 36 hours.
The other great thing about the earphones is the quick-charging capabilities, you can get up to 90 minutes of play-back by just letting it sit in the charging case for just 10 minutes.
The important question is that whether the Sony WF-1000XM3 earphones live up to its stated battery endurance? I am not totally sure yet because I am still on my first charge.
