A:AnswerKris, I see no specs on these ANYWHERE. But I can tell you they are only suitable as voice earbuds unless you don't care how your music sounds.
A:AnswerMy husband and I had Samsung Galaxy S7 and now we have the S8's and the headphones work just fine with them. My daughter had and IPhone and they worked with that as well.
A:AnswerThe quality is good for the price. If you are like me you will lose them before they break. I have had several skull candy brand headphones and they sound great.
A:AnswerYes they are amazing. They are made by the same company that makes Astros the pro gaming headsets. The other cool feature that was unexpected was that they. Lock outside noises.
