But on which earplugs do you think? For phone or the like? Or on ordinary earplugs, where you the sounds from outside shutdown can?

Hmm... Because earplugs for electronic devices do you find of course at electronic shops, at convenience-stores or at music shop. But for the ordinary one do you find in convenience-store, pharmacy shop or in tool-shops.
