[Q] Sennheiser Momentum : Remote control w/ Oneplus One topic

Hi everyone !
I've for project to buy a Sennheiser Momentum 1st Gen or 2nd Gen and I've some questions ;
1)For the 1st Gen : The remote control is designed for iObjects (iPhone/iPads...) but I want to use it on my Oneplus one and I know that pause/play buttons works but up and down don't work so how can I make them to work properly ? (adapter, third-party software,..?)

2)For the 2nd Gen, if I buy one I use it on my Oneplus One so before buy, under the price, I must choose a special brand like LG, HTC,.. who use the same technology than Oneplus in their jack connector or I just choose "Other devices" ?

Thanks in advance :)
(sorry for my bad english)

(tell me if I post this thread in Q/A section of the Oneplus One forum)
