MP3 player questions

    Recently I bought a MP3 player at a garage sale. It's a Phillips
    GoGear Vibe 4gb. It came with the USB cord and nothing more. I never
    used one of these things and dont seem to understand what to do with
    it. (Guess I'm too old for this stuff :) )......

    Ok, so I plug it into my computer. Works fine on the XP or Win2000
    machines (not Win98, needs a driver). When I plug it into a USB port,
    it says it's charging.

    Clicking on "My Computer" it shows up as a drive. I found I can copy
    music files to it the same was as I copy to a Flash Drive stick. I
    can play the music on it into my computer speakers.

    So far so good.....

    I've come to the conclusion this thing is pretty much just a flash
    drive, with a built in battery, and supposedly an amplifier. Except
    for one thing..... (this is the problem). There is no place to plug
    in a speaker (or I suppose a ear phone, because I doubt it could power
    a speaker unless the speaker is self amplified.

    I thought the whole purpose of these things was to be a portable music
    player using an ear phone.....

    There are two plugs. USB and one labelled MIC (microphone).

    Besides these two plugs, it has a volume control, one called
    "options", and an on off lock switch. The front has a small screeen
    and arrow buttons which bring up a list of songs and other stuff such
    as pictures.

    Great, but how the hell do I use it without connecting it to a
    computer? Worse yet, everytime it's plugged into a USB port, all it
    does is charge the battery and the controls on the device do nothing.

    I suppose an instruction manual would help, but if you ask me, this
    thing is little more than a fancy flash drive with lots of useless
    bottoms. Maybe that's why it was sold at a garage sale too.....
    OR maybe I just need a 10 year old kid to show me how to use the
    flippin thing......

    W98 didn't support USB drives natively.
    Yup. And a processor to "play" the files.
    If it has a MIC input, it probably also has a built-in microphone
    and can be used as a voice notepad.
    The "lock" switch is more like a "control lock" ("hold"). It
    guards against buttons being accidentally "pushed" while in
    use (e.g., imagine stuffing it in a pants pocket!)
    Controls on most such devices do nothing while connected to PC.
    You have to transfer files (pictures, songs) to it from PC.
    Some devices are just mass storage devices, others require
    a special protocol to "communicate with".

    More importantly, you have to know what formats the device will
    accept and whether or not files have to be converted before the
    device will recognize them. E.g., often video files need to
    be down-sampled before usable.
    <grin> 99.72% chance there is a mini-jack there for headphones.
    Keep looking.

    Apple's iPod "Shuffle" has the headphone jack doing double duty
    as the USB (!) connection (special cable). Newer generation
    has even removed the buttons from the actual device and placed
    them (+, -) on the headphone cord! All that remains on
    the player is a power/shuffle switch.

    [You can use regular headphones with the Shuffle but can't
    change the volume level *or* change songs! Of course, you
    are still limited by its lack of a display to see titles
    and figure out what is actually *on* the device. :-/
    OTOH, it's about the size of a tie clip (and even has a
    similar fastener for clipping it to your clothing!) so
    it's hard to beat when walking, jogging, etc. and all
    you really want to do is *listen*]

    I rescued a Zune which *looks* like it could be an interesting
    device (which amazed me -- coming from MS!). But, the internal
    hard drive has bad sectors and, typical for MS, there is no
    way to tell the device to mark those sectors as bad! :-/

    Nup. The MIC label refers to the tiny hole near the corner
    which is a built-in microphone.

    The jack between the MIC and the USB connector is where
    you plug your headphones in.

    Yep, you're right. The word "MIC" was so close to the headphone jack
    I thought it was for that. That very tiny hole is a built in mic.
    Thanks too all who replied and those PDF files, I was able to make
    this thing work. Sounds great when plugged into the AUX jack on my
    home stereo too. (But not quite as good as a vinyl record).
    I think it also has a built in radio, but I have not gotten that to
    work yet (not that I need another radio, considering the crap they
    play on the radio these days).

    The mp3 players with a radio I've seen use the earphone wire as the
    antenna, so the length and placement of it will affect how the radio
    function works.
