Pros and cons of CanOpener — for Headphones app for iPhone and iPad

CanOpener — for Headphones app good for

For what it does Id give it 6 stars. But, Im very sorry to see that it is apparently not being maintained. For example, as far as I can tell it will not work with iPhone 6 internal speaker. Thats okay but its just an example of how its not being updated.

Its the only app that does crossfeed and it does it well, in a gorgeous interface and with a few other nice features. Plus the developer seems quite involved !

It is à beautiful app to browse your music, control it. I like the various eq settings. Y

I think thats your app its very good but when Im using the shuffle and I wanna select a music the shuffle turn of automatically , so Im my opinion we could choose the mode of shuffle if its turned on or off

Since i purchase the App, i can only hear music on him. It really increase the performance of your headphone. The only thing i would like to have, is a timmer for when im trying to sleep.

Since Ive found this app Im using my high end headphones twice as much as before. Its just THE App for advanced music lovers IMHO. Thanks so much for this experience to the developers!

Some bad moments

I sent an e-mail to support 2 months ago and still havent gotten a response. It appears this app is no longer being updated or supported. After upgrading to iOS9 it will no longer play the music downloaded to the iPhone native library. Its a shame, I really liked the equalizer.

I like the way this app processes sound. It gives a presence that I enjoy. The interface is pretty bad, but all I need to do is find my playlist and hit Shuffle. This used to work, but then it started crashing as soon as the shuffled playlist started playing. This was last year (2015). I reported it, but never heard a thing (which, unfortunately, is too common with iOS apps). I finally deleted because it was unusable. Recently, I gave it another shot, but was disappointed to find that it still crashes when I try to shuffle a playlist. So Ill delete it again. Too bad, you know?

Be prepare to spend something around $10 if you want to use good features of this app and be prepare to get angry if you already bought the feature and it just disappear of the app. Support? Be prepare to wait and wait and wait...

Absolutely loved the app on 5s with 9.2 but on new 6s+ theres no sound. Hope they fix it soon! DO NOT BUY IF YOU HAVE A 6S OR 6S PLUS!

I read that there is a very short list of apps people use on a daily basis. This is one of mine. Ive got quite a few pairs of good headphones including over the ear, on ear, and IEMs. I prefer Sennheiser, Audio-Technica, and Klipsch for my headsets. (I love my X10i IEMs!) Im a bit of an accidental audiophile... I certainly dont make any grand claims but I know what I like. That said, this app is great for making my library sound great, almost (but not quite) as good as sitting in front of my sound system at home. The crossfeed really is great and whatever math they are using works. I recommend having a listen and play with the settings. Its fun and you will hear a difference! If I had a gripe it is not being able to display lyrics Ive added to my library over the years. The latest versions have been stable and nice looking. Get this!

Works great with sennheiser momentums. Bass more solid, treble and vocals very clear.
