A:AnswerAs normal earbuds they work in any device, but if you want to be able to use them while talking on your phone you cannot with any Android device. These are only phone compatible with iPhones. They do make an Android version, but they are a little more expensive for some reason.
A:AnswerIphone yes, but the only button that works with my Galaxy S5 and Droid Turbo 2 is the pause button not the volume. Best sound out of earphones that I've tested and that's to include Bose, Beats, JLab, JLB, Sony, etc...
A:AnswerThey are in a separate link on the bestbuy page.
If you search " Sennheiser MOMENTUM in-ear MULTI" this should give you the red and black option although it is $11.00 more expensive right now for some reason.
You can also just search for Sennheiser In-ear and it will show up( looks just like this only red and black).
