Pros and cons of KaiserTone Audio Player +HiRes app for iPhone and iPad

KaiserTone Audio Player +HiRes app good for

Ive tried almost every player in the App Store and this one is by far the most well rounded one. The User Interface is the easiest to manage when you think about all of the options one has to drill into with apps like these. But even still this app makes it as easy as possible to enjoy great sound. There is probably another app or two that sounds as good or probably even better than this but, to get those apps to do so will probably be much more of a hassle. If you read this, I would definitely give invest in this app. Its not just an equalizer like most apps, its built to improve the sound of the files. Good Stuff
I was a little hesitant to spend the ten bucks when there are so many free versions out there but this is by far the best value. If youre not quite an audiophile but have to have great sound this is the eq for you. I have a pair of monster earbuds ( around $40) and use this app on my iPhone/iTunes. Those earbuds with this app are comparable to my $200 beyerdynamics cans. You cant go wrong. Being in my 40s I used to have the powerful component system for my music ( receiver, CD player, 20 band equalizer, huge speakers) until 5.1 systems and digital started to be the norm for the times. I really missed that sound that I could fully adjust to my own liking when wearing headphones. I now finally have that with my iPhone/iPad thanks to this eq app. Well worth the purchase. I love it!
Useful, simple, elegant. The best audio app for audiophiles and Hires music. Enjoy with a good DAC
The sound quality is simply amazing! Overall the Kaisertone Player is almost the best but theres something I still missing in the Player: Contra Please fix the genre view in the in the HiRes Database! Pro - High Definition Audio (Up Sampling) supported - PCM up to 32bit Audio Files supported - low & high frequency equalization Missing: - customizable iOS 8 fresh transparent theme (or somthing like that) - Missing Music Visualization - Missing Headphone Visualization (Dolby / Surround also called Quadrophonic with no reverb) - Missing (create & edit) Playlist function in the HiRes Database - Missing Compilation view in the iPod & HiRes Database - Missing play & import music files direct from the HiRes Database (Folder Selection / import) into the playlist - Missing Playlist editing / managing This player only can be better by adding the missing funktions!! It would be so great if the missing functions will be available in the next update!!
I enjoying listening to it. And i can hear what I didnt hear on music before But just need add some equalizer like " pop " or dubstep" to get perfectly ^~^
Good app, little pricey though. The cross fader seems to not work on my iTunes playlists, but works on shuffle. Hope this gets fixed ASAP. Really like the swipe to next or previous; had this on another player and works great while using in my car! Please fix fader to work in all instances; love all the features!

Some bad moments

Very bad interface, no album art cover editor,no .APE file support, nor ogg!
This is a very good app. Id recommend it to anyone who has gotten a good taste for music
really koo app its got great features just that the eq buttons r a little big and confusing to use at first but besides that it has good audio quality
Really nice equalizer! Love the 30 band equalizer. I wish the text color would change for lighter colored themes. Overall, a very nice music player.
This app by far out performs all others! Its amazing!!! My only grip would be the clunky GUI and noise reduction needs tweaking abit. Money well spent! Cheers!!!!
This is a very good player for hires files. DEVELOPER: Please add the ability to access music files from my Dropbox account and to add them to the music database. This is an important feature so users can access higher capacity of music files. Please do not rely on adding files by iTunes.
