No I don't, and I don't think I would, these are imported and nit much support here in the USA if you do have problems, plus I see people all the time having trouble finding accessories that work with them.
They'll even ask on the buds community and people will give you lip service and say "yeah that'll work" then a month later that person will post about how that stock or magazine or whatever doesn't work.
I'd stick with proven brands with real state side support not an importer
