The Buds are all metal and the AUX Plug is also all metal. Clips right onto my bag. Not a huge deal for me because I wouldve changed them anyways but, the description says theyre Omron 50m installed and theyre not. Of course, Im not trying to say that these headphones come close to that other experience, but, that would also be an unreal thing to ask for. If you are mounting it in a spot where you are unable to mount into wood studs where the two hanging holes are predrilled, youll probably want to grab some anchors from your local hardware store to hang this with. Sadly these do not perform much better they seem to be constantly breaking connection even when the phone is in my pocket all it takes is turning my head to loose connection, it is so distracting that l dont plan to use these. It does clean my brushes well! You cant, the wall bolts stop you from doing this. The size tag in the inside have wear, the letters are faded. Similar sizes and different types of Spider-Man.
