Of my 3700 or so miles, perhaps 100 (not counting the MSF parking lot practice) have been *without* ear plugs. Most of that was one trip where I stopped for gas, had to go inside, and forgot to put them in after I was done.
Ear plugs are the way to go... absolutely. It isn't such a big deal around town -- in fact if I ever did much slow speed (i.e. 35MPH speed limit) riding I would probably leave them out for that -- but when the wind noise picks up it is FAR more pleasant to have the plugs in.
I've been trying every sort of ear plugs I can find... both walmart specials and plugs sold in industrial supply places.
Unfortunately, I don't have the brand names of all the different plugs I've tried... but my general findings are:
3M Nextcare Comfort Foam (these are "ribbed for... some reason" and orange) wal-mart ... not very effective, fits loose in my ear, comfortable. Moderately reusable. $4ish for 12 pairs?
EAR (Yellow cylinders of foam) harbor freight ... effective, sharp edges can irritate, but comfortable once you get used to them. Moderately reusable. $0.30/pair (1000-pack for $36ish)
Flents Quiet Please (pale cylinders of foam, similar to EAR) wal-mart ... effective, not very comfortable. Not very reusable. 10-pack for $3ish.
HEAROS Extreme (blue, round on one end, flat on the other) wal-mart ... moderately effective, comfortable for short terms but they get itchy...not very reusable. $3ish for 10 pair.
MOLDEX PURR-FIT (bright green and large, same shape as HEAROS) from an industrial hardware store ... feels very large first time you try them on... I almost just pulled them out and disregarded them. Most effective tested. Comfortable after a few minutes or by the second wearing. Good for long term wear. Fairly reusable. $0.30/pair (1000-pack for $36)
3M 1100 Foam Ear Plugs (bright orange, same shape as HEAROS) from an industrial hardware store ... feels similar to MOLDEX PURR-FIT but slightly smaller. Rated NNR is 26 but more effective than HEAROS and 3M Nextcare comfort plugs (which are rated higher), good for long term wear, fairly reusable. $0.30/pair (1000-pack for $36ish)
The MODLEX plugs (and 3M I think) are available with a connecting cord for a bit more money.
The 3M Nextcare plugs may be identical to 3M 1120 or they may be a softer foam.
Note that ears vary a lot and what is comfortable, small, large, weird, or great for me may be horrible (or perfect) for you.
