App is too expensive!

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.

Perfect !

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 !

Disappointing, Avoid The Frustration

I just purchased, via the SoundHi+ trial period offer, a year’s subscription of this player. However, after an hour and a half’s worth of concerted effort I was left with only a malfunctioning player and a litany of frustration and disappointment.
Consistently, when attempting to play any song, album, or playlist of my choosing, the application repeatedly kicked me out to my iPad Pro’s home screen and left only soaking in the sweat of my own frustration and disappointment.
Unless you have a passion for risk or you’re a gluten for punishment, due yourself a favor, avoid this player.
SoundHi+ does have a significant amount of promise: I hope to see it, someday, come to fruition.

First Rate in Every Respect.

The powerful graphic equalizer alone is more than worth the price of admission. I bought a high-memory iPhone just to keep my vast music library. So,

Two things I'd like to have: 1). A search function so I can search for a specific artist, album, or song without having to navigate the tiny alphabet picker with my large fingers.

2.) A most recently added or purchased group, or a way to sort by the length of time a file has been on my phone.

Thank you for developing and maintaining a terrific product.

こもったのが嫌いな方はEQ設定にアルゴリズムっていうところがあるのでそこをCyber Fortからdecibelに設定変更してみてください。
