Perfect and very convenient

This allows device plugged into the headphone jack of a device, to issue the music or lyrics. I had concerns prior to purchase for coupling to an external headphones since there is no way for the device and for the helmet to enter a code or intervene. In fact it is going very well and very easily without any intervention. We put the Tao in pairing mode (blue and red LED flashing alternately). Then you put the headset in pairing mode. I tried it with a bluetooth headset Creative and this happened without problem. I just tried with headphones zik parrot who has no coupling mode (it just turns the headset) and the coupling is well done.
The advantage of this device is that you can listen to music even with devices that do not have Bluetooth transmitter. It is also interesting for a PC because usually we toujorus bluetooth coupling problems with a PC, even if it was successful the first time. Moreover cla does not block the bluetooth which can optionally be used for something else.
In summary a great product that is very useful
