CanOpener — for Headphones App Reviews

I use the crossfeed to get rid of the headaches I used to get from headphones on long flights. a side benefit is the UI is great. nice product. Pencil EQ is great for squeezing the most out of ear buds in an aircraft environment.

It needs to be updated to iOS9 and doesnt support iPhone 6/6S resolution. No response to numerous inquiries.

Worth a lot more than $2.99!

With most apps the music sounds like its from both sides of my head - two dimensional stereo. With CanOpener there is a sense of depth unlike other apps. I particularly like the ability to adjust the right/left balance that is missing in most iPhone music apps. I do not have equal strength hearing in my ears and I am able to adjust balance so I can hear the music as if the musicians are in front of me, and not inside my head off to one side.

Actually, it LOOKS like it works, but there is no sound. They apparently dont answer email or tweets, so Im not sure there is any support. I wish Id known this before I purchased it. Its a shame such a highly acclaimed app has become a thing of the past... More so that its still in the App Store.

I purchased this program thinking that is was going to be a cheap equalizer for headphones and be similar to the apple EQ presets on every device ever. Boy was I wrong! The app really enhances the sound of your music catalog and makes everything sound as if its newly remastered. And it s not just for headphones, you can use it in car audio systems and anything else that can connect to your Apple device via lightning or standard headphone plugs. I highly recommend this to anyone wanting to tweak their headphones to make them sound better.

This is a great application that can make your music sound amazing with the right head phones. But I do have some complaints and the reason I gave this app only two stars. First, there is not way of saving equalizer and crossfeed settings and give it a profile name. This feature is lacking in both. It would be nice to be able to adjust both the equalizer and crossfeed and save the settings (either separately or combined) with a profile name for later use. As it is, the app seems to save your equalizer settings the way you had them the last time you used the app, but it doesnt do the same with the crossfeed. You have to change the settings manually every time you open the app. Again, being able to save the settings and give it a profile name would be nice. Saving the last settings is nice but not enough. In particular if you listen to a wide range of music styles. Also, an users guide that gives you the basic of what some of the settings are and what they are used for, would be very nice. What in the world is dither? Whats the difference between most realistic, more realistic, and standard crossfeed? "Simplified Delay Algorithm," of yeah I remember that, they thought us that in first grade. Nope, dont think so. I dont know, call me crazy if you want, but I am sure that most people dont have any idea what any of that stuff and other is.

Really impressed with every aspect of this app. Awesome deign choices, delightful experience and most importantly; its absolutely transformative to the quality of music. Didnt even know music from a phone could sound this good.

This app does some great things to the tunes on my devices. The more I use it, the more I like it. Thanks.
