Bluetooth Headphones, Skip Buttons on XT1053 topic

Hello Experts!

I have looked around for a while. I *think* I know the answer, but have a couple queries, I've not been able to find an answer to.

I have a XT1053 - 32GB, First Gen Moto X. Also have a pair of Bose AE2W headphones. I wish I could get it so the skip and pause features would work from the headphones. However, pretty much no matter what buttons I push, it brings up the touchless control - "say call, followed by name/number". I installed the headset controller app, without success.

Do I need to root the phone or unlock the bootloader in order to get this to work? That is sort of the conclusion I've come to. If I am right, what is the difference between rooting and unlocking the bootloader? Does one of these void the warranty and the other not?

Any thoughts would be immensely appreciated. Thanks!

[Q] Someone gave me this Model numbe 337NADEV, is this the same as the XT1053? topic

Looking to purchase a moto x brand new. 32GB Developer Edition. He says the box doesn't show the model number with an XT so he gave me what shows on the sticker of the box. Just wanted to confirm if it will end up being the right one?

Im using it on T-Mobile.
