Beoplay A9 Review –  Sound Quality

Beoplay A9 4th Gen review - wireless multiroom speaker

As for the sound quality, the Beoplay A9 delivers a sweet and gives the subtleties very well. The sound is very realistic and provides very deep and strong bass. I think you can feel the vibration of the air if adjust to strong bass via equalizer. The treble is very crisp and clear. Also, the treble doesn’t feel sharp till pierces the eardrums. All in all, the Beoplay A9 offers balanced sound and is extremely clean. The soundstage is spacious and enveloping, and distinguishing the placement of sound instruments is very clear. Well done for the separate the musical instruments and vocals from each other.
