No sound on blue tooth headphone.

The headphones flash blue when u switch it on.If it flashes blue and red, it means that it is in bluetooth connection mode.So u can connect it with bluetooth devices by switching on bluetooth on your phone or pc.After connecting the red light stops flashing automatically and blue light starts blinking.Hope you understood. :)

If your ear buds have been connected to any device before your TV then it won't work. If you want to connect it to your TV you turn on your headphones, hold the call button for 3 seconds, and you will see ur light flash and connect it to your TV. If this didn't help then go to the manual and check how to connect your headphones to your TV.

To get the maximum volume from your MP3 player you have to increase the ringer volume. To get the best sound you should use either earphones, headphones or blue tooth ear bud. Below you can download a manual for your phone (page 68) explains how to control ringer volume.

You cannot rig up a blue tooth headphones to this receiver with out a blue tooth transmitter ( the Onkyo does not have one built in ). If you have a transmitter it can be plugged into the headphone out socket of the Onkyo ( in front ), just remember that it will cut out the sound from all your speakers when you insert the headphone jack . The advantage though with this connection is you can control the headphone volume using the Onkyo remote.

Try this:

1. With your headset turned on, simultaneously

press the listen volume adjust button marked

+ (volume up) and the call control button.

Release the buttons when the indicator light

begins to flash red then blue.

2. While the headset is flashing red and blue,

use the phone menu to search for Bluetooth

devices and select "510 Plantronics".

3. When prompted for password, enter 0000.

The headset will flash blue when paired
successfully.

Your phone and headset Blue-tooth profile may not be compatible, there are different types of Blue-tooth profile and the moto s9 supports A2DP, i do not know what profile your phone supports you would have to look in the manufacturing specification.

A2DP (Advanced Audio Distubution Profile) Allows you to be able to listen to near CD quality audio wirlessley it also allows a platform for basic function to be used such as play\puase, volume control ect

Blue-tooth profile basically make sure that two devices are talking in the same language and therefore understand the commands they are giving each other, saying that some different profile may work together but as a rule of thumb try to match the profiles

Bluetooth can be very flakey. You might have a defective headset or dongle. It may have nothing to do with the drive.

But more likely is that something is messed up with the bluetooth drivers. If you installed the drivers on the disc that came with it, try uninstalling them. Reset the headset by pressing the volume up and down at the same time as described in the manual. This will clear all devices in memory. Then reinstall the drivers and try pairing again from scratch.

Good luck

Connect the headphones to the bluetooth.
Open the control panel, go to Sounds and Audio Devices.
Click the Audio tab.
Under Sound Playback (top portion of the tab), it says 'Default Device'. Drop the menu down and select your headphones. Click apply then ok, and you should be good to go. 

I can't guarantee that this will stay set up this way. If you disconnect the headphones, you very well may have to run through this again.

The following procedure will re-establish the communication link between the Headphones and the Wireless adapter, this is called "pairing". Before you start please make sure both the headphones and the wireless adapter are fully charged and turned off.
Note: The headphones and the wireless adapter come pre-paired from the factory.
1. Press and hold the power button on the headphones. See Figure 1.

Figure 1

2. Continue to hold the button down until the LED starts flashing red/blue in an alternating pattern. Release the button when the LED starts flashing red/blue. See Figure 2.

Figure 2
3. Once the headphones LED is flashing red/blue, press and hold the power button on the wireless adapter. See Figure 3.

Figure 3
4. Hold down the button until the LED starts flashing red/blue in an alternating patter. The LED will blink blue, then turn off for a few seconds then blink red/blue. Release the button when the LED starts flashing red/blue. See Figure 4.

Figure 4
5. Once both the headphones LED and the adapter LED is blinking red/blue, press the volume up button once on the headphones. See Figure 5.

Figure 5
Once the headphones is paired with the adapter, the LED on the headphones will blink blue once every two seconds. See Figure 6.

Figure 6
When the adapter is paired the LED will be solid blue. See Figure 7.

Figure 7
The adapter may continue to blink red/blue for a few seconds even after the headphones LED starting blinking blue. This is normal; the adapter may take a few additional seconds before the LED turn solid blue.
Once the headphones and the adapter are paired, it is not necessary to pair them again even if the batteries on both units are completely drained.
Additional Note: Repeated pairing will not improve the sound quality or give the headphones and the adapter a cleaner connection.
