8:13KZ Krio - Finally, APP SUPPORT!
The reviewer finds the KZ Krio to be a fun, energetic true wireless earbud that continues KZ's signature bass-heavy tuning, but the main new feature is app support, which was previously missing from KZ's TWS lineup. The app adds useful controls like sound modes, bass boost, and button remapping, though it lacks a custom EQ. Overall, it's a solid upgrade for those wanting KZ's sound with modern app functionality.

7:48KZ Krio | LDAC, шумодав и отличный звук
The reviewer finds the KZ Krio to be a solid-sounding TWS earbud with excellent audio quality, good neutrality, and natural timbre, but criticizes its extremely cheap and fragile case, weak active noise cancellation, and high price for what it offers. They suggest the cheaper KZ Sora as a better value alternative.
