I have a set of QB2 HYG Supra-Aural by Howard Leight. They NRR is 25, lower than the foam earplugs (which are usually 29 or 30). However, I've found that they are fine with all my newer tools and dust collectors as these tools aren't as noisy as my older tools and, therefore, I don't need quite as much noise reduction from hearing protectors.
The the 2 harder foam plugs are tied together with a flexible plastic band which, expands easily and hasn't yet broke for me. The foam plugs don't go all the way inside the ear, but seem to be effective in reducing the noise to the point that it's not an issue. The band fits comfortably around my neck and, since the plugs don't go into the ear, they can just be taken out or put in quickly and frequently without a problem. The band will keep the plugs comfortably hanging around your neck either with the band in front or around the back of your neck.
If I am planing wood for a long period of time I still use the crushable foam one-use ear plugs because they are the most effective I've ever used (Sparkplugs by Moldex with a NRR of 30), but I use the Howard Leight QB2's the rest of the time. They work great for me. I'm sure you can find them online.
