SureTech S1
These earbuds offer a unique touchscreen case with controls and an AI translation app, but opinions are sharply divided. Some users love the sound quality, features, and value, while others report defects like only one earbud working or find the translation feature inaccessible without a proper app store listing. The build quality of the case feels cheap to some, and the app setup via QR code raises security concerns.
Pros
- Touchscreen case controls
- AI translation feature
- Good sound quality for price
- Equalizer presets on case
- Responsive touch controls
Cons
- Only left earbud works for some
- Translation app not on official stores
- App setup via QR code feels sketchy
- Cheap-feeling charging case
- Earbuds stay connected in case
