I've always wanted to buy some good earplugs to protect my hearing from noisy environments (es. near public transport in the city). Does anyone have a product they recommend?
There are also much more expensive concert earplugs for musicians, which do an even better job at preserving the spectrum, but I'm not that picky.
They're cheap and come in packs of 20. So I stash a handful in various places so I always have some accessible. In particular I keep a few in my essential medicine bottles since I'll have those while traveling. I find I can reuse them a few times, but if they feel off or dirty the cheapness means I don't hesitate grabbing a new pair.
The one thing I like about them over the similar Etymotics is they don't stick out of your ear quite as much.
