What reviewers say
Reviewers agree it sounds excellent, with powerful but controlled bass, clear treble and a wide soundstage, and praise the retro design and tactile controls. Tom's Guide found it stays clean at high volume. The shared complaints are the lack of Wi-Fi streaming and a voice assistant.
