The HMDX Craze has friends—like lots of them.  Invite them 

along next time for an even more epic night.  You can check 

out all their online profiles at www.hmdxaudio.com.

Setup is pretty easy, but we put a manual together just in case 

you need it.  It’s full of information and sarcasm—just like that 

English teacher you had that crazy semester.

Like any amazing couple, this one starts with a connection—one between 

your device and the earbud’s Bluetooth.
Here’s how it works:
1.  We know you’re probably going to think, “derp” with this one, but we 

have to say it: Make sure the smartphone, tablet or computer you want to 

hook up to the earbuds has Bluetooth. (There. We got that out of the way.)

2.  Turn on the earbuds and look for the little blinking light.
3.  Do whatever your device needs you to do on its end. (We don’t know 

what you’re using. We’re not spies.)

4.  Look for HMDX CRAZE in your device’s Bluetooth list or click 

YES—whatever pops up on your device—and BAM you’re connected.

5.  Now hit PLAY on your earbuds and crank it up—or down if you’re lame.

You’re probably only going to have to do this once, unless your device goes 

through a major I-just-dropped-it-in-the-pool kind of reboot. The device and 

Bluetooth will find each other every time just as long as the earbuds are set 

to Bluetooth and your device’s Bluetooth is, you know—on.
If you’re connecting to a computer, you may have some extra steps on that 

end.  You’ll have to get that information from the computer company.
Depending on your device you may be prompted to enter a pairing code.

If prompted enter “0000” as the code. 
To clear the pairing history hold the POWER button for 8 seconds.
Note: If you turn on your Craze Earbuds but haven’t started the party,

they will automatically power off after 2 minutes of unpaired inactivity.

 Information like where you bought it and how you’re 

1.  That’s the power button, press and 

hold for 5 seconds to power on.

2.  Turn the music up or down. (Wait, why 

do you need to turn it down?)

3.  Push it to play, push it again to pause.
4.  That light lets you know when your 

device is charging and when Bluetooth 

has the hook-up.

5.  The power cord goes here.

Charging the earbuds is so easy you’ve 

probably figured it out by now, but just in 

case, you’ve got two options: your 

computer or a wall outlet. 

1.  The cord that came with the earbuds 

—the one with the USB on one end and 

the Micro USB on the other—will work 

with your computer.  

2.  If you want to use the wall outlet, you’ll 

need to pick up a power cord with a 

Micro USB the next time you’re at the 

store, or use any USB AC adapter, 

including the one for your cell. 

Now go get ready for an epic night while your earbuds do too. 

They need about 3 hours of me time for 4 hours of party time.
