Sir, Please guide me to pair my VMX 100 bluetooth headset to my Dell streak(android OS) and to my Notebook (windows 7). thank u

To Pair the Sennheiser VMX 100 headset with your cell phone:
At the same time as you open the mic, you also need to push down on the bottom/volume-down button on the side of the earpiece and hold this down (at the same time as opening the mic) until the light flashes red and blue alternating. (Just to clarify, it is the button that has an arrow pointing toward the Sennheiser logo). If asked for a code, enter "0000" (four zeros).
This video shows the bluetooth earpiece connecting to an iPhone 4S running iOS 5.0 (not jailbroken). This is the standard way to pair these devices (and it should work for Android phones as well), but as a disclaimer:
If anything should happen to your phone or your Bluetooth earpiece, it is not my fault.

Hello, first no one will give you free unlock code for your Dell Streak 7 except your network provider. You can ask directly to your network provider to get Dell Streak 7 Unlock Code, but you must prepare a good reason why you need that code otherwise you will get a charge aproximately $80 for that unlock code. The other way you can buy Dell unlock code from third party sites with cheaper cost rather than buy from official network provider. I hope my solution can solve your problem.

Have you tried to put your headset in pairing mode first? Anyway, in order to do it, starting with it turned off, press and hold the answer/end button for some 8 seconds, until the indicator light is flashing alternately in red and blue. It is in pairing mode now. Then, on your Android device, go to 'Settings > Wireless & networks > Bluetooth Settings', and, if your device's bluetooth radio is turned off, turn it on, by ticking the 'Turn on Bluetooth' checkbox. Then, on that same settings page, click 'Scan for devices'. After a little while, your headset should appear on-screen (most probably at the end of the list). By clicking over it, the pairing process should be automatically done. Otherwise, if a pairing mode (or PIN, or passkey) is requeseted, enter '0000' (four zeros). You'll see an inidication on that settings page that your headset is connected for phone calls.
By the way, if your headset's user guide happens to be missing, feel free to download it from this location.
Please, let me know if you need further informations.

Make sure Bluetooth is turn on in your Blackberry.
Set the headset to pairing mode and choose find devices on your blackberry. When it finds the device, tell it to pair. The passcode will be 0000.

In order to have music streamed to a bluetooth headset, it must bear A2DP (Avanced Audio Distribution Profile). You see, all stereo bluetooth headsets available on the market do support that profile. Nevertheless, the VMX100 is a monaural headset, thus bearing both HFP (Hands Free Profile) and HSP (HeadSet Profile) only, which are suitable for phone calls only.
Well, depeniding on your phone platform, you might find applications around which route all audio to a monaural bluetooth headset. However, you would, most probably, find the sound quality to be pretty poor.
Please, let me know if I can help you any further.

Try the headset that is compatible with you Motorola Q9h GSM phone.

Hello and welcome to fixya.

To pair your VMX100 with your phone. Take your phone and the vmx next to each other. Turn on the VMX by opening the microphone boom, it is switched on. if the vmx is not paired it will automatically go to the pairing mode.

the led should flash in red and blue to indicate that it is in pairing mode.

If you have previously paired it with another deivce then you have to enter to the pairing mode yourself. Open the microphone boom as you would turn it on. while you press on the bolume button at the same time.

The led on the top will flash alternatingly in red and blue to indicate that the headset is in the pairing mode.

On your phone, you need to make sure the bluetooth is turned on and that you are in discoverable mode, then look for bluetooth devices nearby.

The VMX 100 should show up. connect to it and your phone should ask for a passkey which is 0000 four zeros.

if the pairing was a success, the led on the top will flash slowly in blue.

your headset is now paired, if not, then repeat the process.

Your phone should be able to transfer the call audio to the headset either automatically or manually, have a look in your phones manual on how to transfer the call to the headset or how to use the headset with the phone.

Have your phone do a search for Bluetooth devices (have the earpiece turned on) and when it locates it, type code "0000" to pair.
