Sony xperia xz hi res smartphone

[concordus]

Hi

Just recently sony introduced xperia xz, maybe you had opportunity to test it for sound quality?

Hi-Res just means it can play files at a high sample rate and bit depth, but many Android phones can do that now.
 
Can't speak for it but here are GSMArena's measurements - seems pretty average. Finally the DR with headphones is over 90dB but the IMD is a bit high. Usually I take them with a grain of salt because they gave "bad" measurements for HTC 10 and LG V10. That said, their measurements for Sony Xperia Z5 were pretty close to those by Android Authority.
