Audio Equipment and Home Theater Audio : Problem with my Beats

Ok I was given a pair of Beats. The problem is a lot of the songs from my collection won't play properly. It's odd the music will play just fine it's just any lyrics won't play at all or their really soft and hard to hear. This isn't a problem with all my songs but a good percentage of them.
I've asked a lot of people and n9body knows what I'm talking about. Any fixes? Has anyone else had or heard of this?
I googled it and came up empty.

What are you using to play them? iPod, or a computer? Have you tried copying them to a different device and seeing if they sound different, or using a different set of headphones? I only ask these questiosn because it may be a hardware issue or software settings - iTunes for example has EQ settings in which you can adjust the sound of the audio.

Tried my phone (galaxy note 5), iPod (old and hasn't been updated), and girlfriends phone too.

Where did you get the sound files? From a karaoke bar? It appears that something is removing the vocals on purpose. Since vocal tracks can't be eliminated completely, you'd hear some residual vocals, just like you describe. Since you've tried different players, it must be the files themselves. I don't know how the cans fit into the equation, if at all.

Can't be the files. When I use regular earbuds the songs play fine.
I think the Beats are fakes. There's no Micro USB port.

If the common lead of the cord was open (broken), all you'd hear would be the difference between the left and right channels, which would cancel out stuff that was mixed to the centre, like vocals.

Doesn't do it for all my music. Probably 70% of my tracks
