Overview
Tozo makes these small in-ear earbuds with an app for tuning the sound across many EQ settings. Two microphones help during calls, and a compact charging case tops up the buds on the go.
The reason to look at the A1 is the small size and the app control for sound tuning. The limit is the per-charge runtime, which is much shorter than the case total, and the lack of active noise control.
Who it's for
Calls, school, travel and everyday music listening suit a small bud and case that fit a pocket. Marathon listeners and people who want noise cancelling or published codec support should check other options.
Pros and cons
- Very small and light
- App with many EQ settings
- Two microphones for calls
- Case adds long total runtime
- Short runtime per charge
- No noise control
- Codec support not listed
- Warranty terms not detailed
Performance notes
The small driver favors clear mids over deep bass, and the fit of the ear tips decides how much low end you get. Call quality depends on the two microphones picking out the voice, and the case refills the buds several times for the total runtime.
