3M Earplugs Stringed E-A-R Push Ins

　Ready-made earplugs are not so expensive, so they are good for musicians to use as a starting point to protect their ears. For musicians, the most common type is the one that reduces the sound by 20 dB and has a cord around the neck. At the time of writing this blog, the earplugs with strings I purchased cost about 3 dollers.
