## What reviewers say

**Boss Katana-50 Gen 3** — Only one whitelisted tester, MusicRadar, published a hands-on review covering the Katana 50 Gen 3; it is positive but qualitative with no lab measurements. Praised for clearer, more detailed and more responsive tone and the new 'Pushed' voicing; the sole gripe is that Bluetooth is a paid optional extra rather than built-in. (1 sourced review.)
