These are all Field Electronic cymbals (The Classic series) I am the only owner of them. I have the 14" High Hats (both top and bottom) I have never used them... not one time. As you see in the pics the bottom high hat is dirty compared to the top. I did not wipe it down so you would see what happens to them over time. I had it wrapped in a towel in a box and it cleans right off cymbal cleaner. I was afraid to wipe it because of it being electronic and you can not see it if you set it up anyway. I will leave that up to you if you want to clean it. I did clean the tops of all of them and it took the Field logo off. I did use the rest of the cymbals for about a full month and then we moved and they were never played again.  The set includes an 18" triple zone ride, a 14" crash and a 10"  splash and of course the High hats. None of these cymbals choke at all. They all work fantastic with a Alesis DM 10 module or a Pearl Epro kit. I am not sure about anything else. They all connect like normal electronic cymbals. I paid about 1100$ for them and didn't even use them like I planned too because I am turning the music room into a nursery :)  Hopefully, someone gets to wail on them. If you are unfamiliar with Field Electronic Cymbals Check them out online. Thier website will tell you everything. But remember, None of these have the choke ability.
