Those are basically tamborine jingles riveted to the cymbal. I've got a junk cymbal I'm going to rivet beer bottle caps to.
There only a very few truly "junk" cymbals, and unfortunately many of them are some thin stamped MIJ sheets from the 60s. Most any cymbal can make a desirable sound. It just depends on your style of music, and mainly if play effects musics for movies...but to say anything other your "favorite" cymbal is junk...not really fair. I happen to like the sound of certain NS-12 with certain drums, and many styles of B20 with other drums. The best drums in the world make certain vibrations that don't really sound great with the perceived best cymbals. This is all physics and vibrations technology. Your favorite cymbals may not sound great with certain other drums, or in other settings.
Guys, a lot of cymbals that are considered "trash" or "entry level", even "intermediate"...sound good with drums other than yours. My "POS" MIJ drums, that many local drummers are now asking to record, sound best, IMHO sound great, with NS-12 Ludwig Standards/Paiste Stanople or any of their other stencils from this era. They just work.
