User Reviews

Users largely praise SoundHi +EQ30 HD for its studio-like sound and the deep, flexible graphic equalizer that boosts bass and mids with little distortion. Many cite clear value for the money and strong performance with wireless headphones. However, recurring concerns include the subscription pricing and reports of stability issues (crashes and bugs, especially after iOS updates). Some users also point out missing features like a built-in search/library organization, Apple Watch support, and limited Apple Music compatibility, as well as a perceived learning curve to use effectively.
Pros
  • Studio-like, distortion-free sound with the powerful graphic equalizer.
  • Extensive customization options for precise sound shaping.
  • Improves wireless headphone listening with clear, punchy output.
  • Generally considered good value by many users for the feature set.
Cons
  • Pricing: expensive subscription model; many users prefer a one-time purchase.
  • Stability and reliability issues (crashes, bugs, issues after updates).
  • Missing essential features (search function, library management) and usability concerns.
  • Limited compatibility with Apple Music.

Your app is too expensive and should only be a one time charge. And you need to make it so a person can add their own backgrounds.

This app is well worth the money ! Every song is like being in the studio ! Clean and crisp with no distortion! Tons of features to craft your sound that way you want ! The perfect companion for my Sennheiser HD 450BT Wireless Bluetooth Headphones ! If your having issues maybe your not using it right or your internet is the problem ! I love it and have had it for three years now with no issues !
