What reviewers said
KZ S1 Hybrid
The KZ S1 Hybrid is an affordable true wireless earphone that combines a dynamic driver with a balanced armature in each earbud, aiming for detailed sound at a budget price. It offers basic features like touch controls and USB-C charging, but its short battery life and lack of ANC or multipoint connectivity hold it back. Overall, it delivers decent value for its cost, though newer competitors have since raised the bar in this price range.

- Pro:Very affordable price point
- Pro:Touch controls and USB-C charging included
- Con:Only 3 hours of playback per charge
- Con:No active noise cancellation despite initial specs
- Con:No multipoint Bluetooth pairing

- Pro:Long battery life with wireless charging case
- Con:Microphone quality is mediocre
- Con:Touch controls can be inconsistent
