When i plug my skullcandy agent headphones into my ipod and my computer i can hear the music but just the instrumental and the voices are like echoes or whispers. the headphone seems to look in good condition. Also i have only had the headphones for just over a month now.

I would say that if they work fine with other devices then your input jack on your ipod is bad. First I would plug other headphones into your Ipod and see if the problem persists. If not the case then I would plug in your headphones into a known working device and wiggle the wire at the connection point to see if you can duplicate the problem. If this does happen then you need to replace the connector (1/8th inch stereo male plug) on your headphones.

Sounds like there may be a problem with the cord.
Try plugging in your headphones and playing some music and moving the cord around. If the sound cuts in and out then you have a lose connection and will need to replace your headphones.

Your Headphones may be broken. Apple headphones usually wear down over time and eventually break. I would recommend purchasing skullcandy headphones or even Beats headphones depending on your style and budget. http://www.skullcandy.com/ http://www.beatsbydre.com/

See my tip on replacing dodgy cables and plugs on headphones.

Make sure you have the memory card in the unit or it will not charge. If that doesn't work call up the company and ask for a refund/replacement.

What I have seen is that some will just keep on charging for no reason but they wont turn on. What I did is that once I unplugged the headphones from the computer I took the SD card out and I moved the white switch-like thing towards the top of the card. Once I put my SD card in and tried to turn it on again it worked. Try this if your headphone wont turn on but will still charge, it should work.

They can only be in Mp3 format or WAV I think. I know Mp3 for sure. If the music is in any other format you will have to reformat the music in order to get it to play. It's something really obnoxious about the headphones which could've been easily avoided. Just look up a program like Switch or an online converter for free. It's pretty simple.

An old trick to remove vocals from a song was to rip the right channel, then the left, the combine them (since vocals are typically mixed in a third 'center' channel, though things like reverb or echo are applied to the right and/or left channels which sounds like what you are hearing).

I would play with the balance and mixer settings and see if you can get the vocals back. Also try other speakers or even headphones and see if you have the same problem.

Hope this helps!

The thing you need to realize is, the headphones are not defective. Headphones cannot choose to individually make voices/game noises/music louder or quieter. Either they play audio or they dont.
What your issue is, is configuration with the xbox (the soucre FEEDING the headphones) Only there can you choose the amount of voice/game noises/music and their respective levels.
Below is a link that headphone company has on their site for the settings you need to change in your xbox.

Any further settings will need to be assisted by an xbox support person.

Try to check the SD card, switch the protector, then try to play it again by pressing play button 3sec (the indicator will turn into blue), then the music will play.
