## KaiserTone Audio Player +HiRes Reviews in Vereinigte Staaten

### ***** "Please increase the gain level."
Please allow for the gain level to go past 100%

To at least 300%. Please.
-- SuperBlaq, 2024-11-27

### ***** "Fast app update to fix ios 18"
Best app for my iphone 15 using usb c dac
-- BlazeKitten, 2024-10-15

### ***-- "DOP way no sound"
Iphone 15pro+Fiio Ka17 or Fiio Q7 play DSD256 by Dop way no sound. Please help
-- maplewave, 2024-07-24

### ***** "Review"
Hello the apps are wonderful I don’t have ITunes and I listen to offline music apps on Iphone. Would you be kind to add a feature that transfers any music from offline music apps as well. Thank You. The offline music apps iPhone also can add music from PC or laptop as well. iTunes is very complicated and I no longer use it.
-- Murat Dzh, 2024-05-30

### *---- "Misleading horrible app"
You can’t play hires sound files stored on your phone…so this app is pointless and misleading. Description did not say you could only play music purchased from Apple. Just awful.
-- Sleep875, 2024-04-16

### *---- "Can’t Delete Songs Permanently"
This has to have the worst user interface of any app I’ve used. It duplicates my song files and there’s no way I’ve found yet to delete them and keep them deleted; they keep coming back! There’s also no way to point the app to a specific folder with music files. It has a folder to load music files, but even if I leave that folder empty, it finds the files somewhere else. This lack of functionality is baffling. I deleted and reloaded the app and all files, then reloaded everything and it’s the same. There are no instructions on how to use it. Does anyone know how to delete songs and playlists and to keep them deleted?
-- StuPhotog, 2023-06-10

### ****- "Choppy music"
Very good app
Takes a lot of CPU
Music is choppy if I open 2 or not Apps with Kaiser
-- Airplay101, 2023-02-26

### ***** "KaiserTone app"
I bought the app here I am on ios16.3 using iPhone 13 and the 30 band eq is greyed out along with the surround sound option I am using Apple Music files to play I am able to adjust sample rates and so on except for those features listed above how do I resolve this probblem?
-- Toddham420, 2023-02-01

### ***** "Audiophiles rejoice!"
So I have tried many iOS music player apps to see if they actually make a difference in sound quality. Most sound the same as Apple’s built in music player app. But KaiserTone is different as it sounds so analogue. My trick is to disable all the extra processing in the app, turning off all equalization and setting artwork thumbnail sizes to smallest. This puts less stress on your iPhone’s processor, creates less jitter and gives better sound quality. Try it!
-- Birdy26, 2023-01-26

### ***** "The best music app"
Love it and there’s no music app that compares. If you want and love the best quality, then this is the perfect app for you. 
1. The Bass is not distorted 
2. The equalizer is spot on 
3. Super & way loud and enhanced amplifier for your music.
4. The settings are easy to use and control.
5. Great options to customize your settings.
6. No need to change. Just keep everything like it is.
7. You will experience your music in a way better sound. It will change your music and you can hear things in your music that you normally wouldn’t never hear in a less quality music app.
-- Lightning Angel, 2023-01-07

### *---- "Just wanted volume boost for iPod touch"
Wasted $10 on an app that doesn’t do what the paid reviews show it will do. Not intuitive. Wasted money.
-- AlaskanPhilT, 2022-10-30

### ***** "great app for AIFF"
i’ve been using this app recently & i got to say it is amazing. i still have to play with all its features but great app for best sound nonetheless
-- YUNG_MILK, 2022-07-17

### ***** "Best music player app I have ever used"
Everything’s perfect pitch controll crossfader and excellent sound this is the absolute best app available for high quality sound and options Ty Kaiser
-- jet4471, 2022-05-27

### *---- "Needs some fixes quickly"
I have owned the app sense it was called superloud and I have never had this problem till the lass update and I have tried to reinstall the song that I bought and it still shows on the app that I have not bought them, can you fix it as soon as possible I use the app every morning I go to work and when I can’t play the songs I have Ben playing for months it is a little bit annoying, really hope you can fix this problem this is probably on of the best eq app I have ever used, Thanks, Tristan D
-- Tristan Delaughter, 2022-01-15

### ***** "La mejor"
Súper Fina tienes el control de toda la aplicación
-- MAELO 23, 2021-12-18

### *---- "Doesn’t do what was expected"
Paid $9.99 in the App Store for this app.  Was suppose to allow me to enhance volume and allow me to increase volume on headphones.  It doesn’t do anything my regular volume button doesn’t do.  It was a waste of my money.
-- GoBlueGuy, 2021-09-28

### ****- "HomePodミニ"
HomePodミニをステレオ設定で使用してますが、購入した曲を再生する時には何故かステレオにならず、1つのミニからしか音が出ません……
-- Pakatyan, 2021-06-01

### *---- "Doesn’t Work"
Don’t waste your money!  This app does absolutely nothing.  I tried to boost my IPhone volume when I Bluetooth.  Won’t work with pandora.
-- Walker Tribe, 2021-02-24

### ***** "Awesome"
It will be perfect, if can play ISO file, Tidal or Qobuz. Anyway, I love it so much.
-- h3nddy, 2021-02-21

### ****- "Best EQ For Playing Your Own Music"
Only downside is this app is not fully functional in CarPlay
-- jimwat01, 2021-02-07
