I've looked in the manual (digital) and it looks as if these are only designed to pair with smart phones and tablets. Certainly bluetooth isn't recognising the headphones when they are switch on.

Is this correct?

Hi Alwyn. Thanks for posting.

From their website, the following comments imply this is for Smartphones and similar devices:

1. Immediate pairing to smart devices using NFC connectivity

2. Comes with an attachable audio cable for use in environments where Bluetooth® connectivity is not permitted

Sorry about that:)

Hi Alwyn - I use some Sennheiser wireless 'over the ear' headphones (2.4 GHz) for my den stereo, so I assume that is the brand? Are the 'earbuds' below the ones in question? Visited their website and found a Q&A question (2nd pic) - might this issue apply? Dave :)

I use a pair of Sennheiser Momentum 2 (Sennheiser MOMENTUM wireless Headphones with integrated microphone) with my Macbook Pro, iPhone, Mac Mini and it all works fine.

Sennheiser using "Momentum" has a brand that covers MANY different variations of their headphones, please provide SPECIFIC details of which ones you are referring to.

AFAIK, Bluetooth is Bluetooth is Bluetooth. It's not device dependant.
There is no special Bluetooth for smart phones and some different Bluetooth for the Mac.
The M2 EABT headphones do support Bluetooth according to the manual so this should work if the setup procedure is followed.

NFC (Near Field Communication) as mentioned in post #2 is a different type of wireless connectivity.
That one is not supported by the Mac - wouldn't make any sense for the Mac to support that since the range is very limited, 4 cm or 1 1/2 inches per the Wiki.

The M2 EABT headphones support both, Bluetooth and NFC.

Those are exactly the headphones I have, mine are white and they work fine with all devices I've connected it to over Bluetooth.

I'm still having no luck. In Settings/Bluetooth my mouse, keyboard and iPhone are all showing up as connected. In Settings/Network Bluetooth PAN and Bluetooth DUN 2 appear with a self-assigned IP for the former and Not Connected for the latter.

Are the headphones paired with another device? Maybe when you turn them on, they connect to that device?

Press the power button and hold it down until it says "Pairing" and it should appear in the Bluetooth dialog. Your Mac doesn't have NFC, so don't bother with the Network settings, that is unrelated.

Once paired, you need only turn it on with a shorter press of the power button to have it come on and say "Connected" if I remember correctly (have too many BT devices that do different things).

hold the shift option keys and click the Bluetooth icon>Debug> try a reset


If that does kick start it, try the following solutions:

- Press and hold the power button until the LED flashes red and blue, and the voice prompt says "pairing."

- To clear previous pairings from the headset, follow the instructions above to put the unit into pairing mode. While keeping the Bluetooth button pressed, hold in the multifunction button until the LED flashes purple 3 times and the unit goes back into pairing mode.
