VVX 410 To Bose 700 Headset

I am aware that a VVX 410 Polycom phone does not have any bluetooth feature to connect headphones to it.  My question is the following,

I have a Polycom VVX 410 Polycom phone and a Bose 700 headset.  If am not mistaken, the VVX 410 has an RJ9 phone entrance and the Bosee 700 is 2.5mm to 3.5mm.  If I buy a mic 2.5 to 3.5 and an adapter 3.5mm to RJ9, will this work to connect my headphones to the phone?

Is there any way that I can connect bluetooth headphones to the phone? by a cable of course.

I was thinking of getting this two cables .
