## Review summary

Wavelet is praised for clear sound improvements with AutoEQ and AI-assisted tuning, AI-generated curves for unlisted headphones, and extensive customization in the paid version. It also benefits from free AutoEQ support and broad hardware compatibility after setup. However, users report reliability issues, licensing bugs, lost presets/settings, browser-related limitations, and device-specific conflicts (legacy mode on some devices, smart-glasses reboots). Overall, strong potential tempered by several bugs and setup frictions.

### Pros

- Significant sound improvement across a wide range of headphones, especially when used with AutoEQ.
- AI-assisted curve generation for unlisted headphones and easy CSV/TXT import/export into an AutoEQ workflow.
- Full version offers extensive customization with a user-friendly interface.
- Free AutoEQ support and broad hardware compatibility after setup.
- Works well with common gear (e.g., Audio-Technica headphones and Fiio BTR5) and helps optimize listening.

### Cons

- Reliability is uneven: listening sessions often aren’t recognized without multiple restarts.
- Premium features can be buggy or misreport as free; some users are stuck on the free version despite paying.
- Presets and saved settings can disappear or reset after changes, with little recovery guidance.
- Not compatible with media from web browsers, limiting usage in some scenarios.
- Device-specific issues and conflicts (e.g., legacy-mode requirements on certain devices and smart-glasses causing reboots).
