Maybe. They should show up as Bluetooth devices on your MacBook Pro, but they must be paired with them first, and of course they must be charged up (if they have built in batteries) . I don't know if you have have a bluetooth device paired with more than one thing at a time. I suspect, in the case of headphones, probably not. So, you'd have to un-pair (or remove them) from the bluetooth menu of your iPhone first), and then pair them with the MacBook Pro, using the Bluetooth menu. So go to your Bluetooth menu (looks like a Capital B, sort of, and it's right next to the wifi icon on the top of your screen). I tried getting a user manual from the Utaxo website, but it doesn't look like it's working.... not really much in the way of basic support, eg, this is how you set 'em up..... in the Bluetooth menu on your MacBook Pro, you should make sure that Bluetooth is turned on and that your MacBook Pro is discoverable. Kinda silly, I know, but it's basic and has to be said....once....
so< I found this>
make sure the headphones and your bluetooth device are near one another (within about 3 feet/1 meter)
press and hold the power button for 5 seconds until the LED flashes blue and red. Utaxo should come up in the bluetooth menu. click on the name to connect
to clear the pairing cache, hold the power button down for about 5 seconds and listen in the headphones for "Pairing"
and apparently it'll say the words "power" and "Pairing" while it's doing so and you're turning it on, then it should be automatic from then on...
if that doesn't work, try doing a reset smc/pmu and zap pram on your macbook Pro and try again, after you have turned off the headphones, restarted your MacBook Pro and then turned 'em on and re-paired them......
You may also get interference from other paired bluetooth devices
good luck
