## Review summary

Users praise Nano SigmaPlus for its simple, elderly-friendly interface and seamless Bluetooth pairing with nano hearing aids. The app makes it easy to adjust volume, switch between modes, and test hearing, with independent volume control per ear and environment presets. However, multiple reviews note that advanced features such as per-ear EQ bands, compression, and built-in hearing tests available in older versions are missing in newer updates. Some users also report inconsistent left/right channel behavior, and overall feature depth may feel limited for power users.

### Pros

- Simple, elderly-friendly UI and easy navigation
- Quick Bluetooth pairing and reliable connection to Nano hearing aids
- Independent left/right volume control and multiple mode options
- Built-in hearing test/sound check to verify performance with aids
- Environment-specific modes and presets for different listening situations

### Cons

- Removal of advanced features (hearing test, EQ bands, compression) in newer versions
- No Band (EQ) section / limited frequency adjustments per ear
- Inconsistent or limited left/right channel behavior (some reports of changes applying to both ears)
