There are multiple bolts and two plastic push pins, that are a bit difficult to release. They look just like the picture! Very happyTotally worth the price! The notch is for the cable side, which orients the top part to basically be reversed. they should have covered it so it doesnt get torqued by the barbell and rip. made it very easy to have long phone conservations with work colleagues and friends in comfort. I went for the large size in the black colour. The factory silicone ear bud was problematic for me. She told me the story about how she came to buy them, and I just had to have a pair as well. These are freaking awsome my sister has the powerbeats 3 and these have the same same quality, Id rather buy these for 40 than spend 100 for the same quality.
