Motorola MOTOROKR wireless headphones, help!

[Eärendil]

Im about to buy a 32Gb Ipod Touch : ), and I really want the s9 headphones, but i have some questions.

I was wondering if you could help me (by the way, im buying them off amazon)

First of all, Im going to use my ipod with a DLO VideoShell case, so im a bit worried, because the Bluetooth adapter might not fit in, and i dont want to remove the ase everytime i want to use the headphones.

so here it goes:

1) Is it better to buy the headphones with the official motorola adapter?

http://www.amazon.com/Headphone-S9-...4?ie=UTF8&s=electronics&qid=1203203530&sr=8-4

Its $128.......


2) What if I use this adapter? will the headphones built in controls work?
http://www.amazon.com/Jabra-Bluetoo...3?ie=UTF8&s=electronics&qid=1203204007&sr=8-3

Its a lot cheaper than option 1)

3) This option will solve my case problems, but im also wondering if the built in controls will work this adapter

I need your help guys, option 3 looks so cool, as it can be used with a case, but i want the headphones control to workmainly because you dont have to take the ipod out of your pocket to change song/pause/change volume.

I really appreciate if you could help me, as I live in Mexico, and its a mess to return things to amazon.

: ) thanks a lot (if someone ever reads this)
