Review on Sony SRS-XB23 Portable Speaker with IP67 Waterproof, Extra Bass, Bluetooth, Built-In Mic for Phone Calls - Black (SRSXB23/B) XB23 by Kitti Sak ᠌

The sound was disappointing. I listened to her in the store and in comparison with JBL and she loses the same way. I''m not a big fan of the JBL sound, but here it''s generally kind of slurred. I downloaded the Sony application, twisted the frequency sliders and did not feel any effect - the sound remained flat as it was. Judging by the number of reviews, most people like the acoustics . I definitely don''t.
