Here is what I thought I could do, with a NFC laptop, headphones and mobile (Android) I though I would be able to touch the headphones to either the laptop or phone and it would automatically switch to that device and pair, is this something I should expect to work or have I completely missed the point?

Depends entirely what hardware you're using.

The concept is one that works, but there are plenty of catches to be aware of.

So my concept is feasible? All devices are made by the same vendor so I was hopeful they would talk to one another.

Lots of devices support this functionality.

I guess the scenario here is that nobody has any idea what devices you're talking about and whether they support this functionality or not.

Oooops, somehow I thought ESP had evolved ;-) Vendor is Sony, Headphones are DR-BTN200, laptop is Vaio Pro 11 and mobile is Xperia M (Telecom version).

Maybe I'm not hitting the NFC sweet-spot?

As far as I was aware, NFC is just a loader for a Bluetooth connection, so the two devices would have to have the appropriate support for the correct BT profile in order for the to communicate, and then I would expect there to be some user level software that makes use of the connection.

I read the manual for the headphones, I suggest you do the same...

Yes, the headphones are fine, it's the other ends who documentation is vague.

What I struggle is how NFC is going to add any added value.

While there might be advantages for initial pairing options, this has already been proven with existing technologies using Bluetooth LE (Apple TV has iBeacon). Furthermore, most headphones and speakers automatically reconnect when bluetooth is switched on, tapping is an unnecessary action.

Unless your headphones are paired with more than one device and you want to easily choose which to use.

A fundamental purpose for NFC is to signal that a physical person has requested a transaction to be initiated and that it is ok to set up a radio connection with the other device. Pairing hardware is not part of this purpose, that is what Bluetooth does - create a radio connection and specific pairing.

Win NFC you still need the correct BT profile installed, I doubt anyone would go to the effort of writing a BT headset profile for NFC when it is much easer just to use straight BT itself (another way of thinking about it - why bother to require the devices to be touched to each other [what Near Field Communication is] when you can stand 30 feet away and do the same thing).

as above, ease in switching the use case I was hoping NFC would address.
