I’m a big fan of SureFire’s Sonic Defenders and use them anytime I don’t require full over the ear protection. The secret patented Hocks Noise Braker filter that allows sounds, at safe levels, to pass through into the ear canal, while potentially harmful noises (above 85dB) are reduced. If you aren’t familiar with these ear plugs they are molded from a hypoallergenic polymer for left and right ears and are also sized for proper fit. They also feature a stopper which can be closed, offering a 24dB Noise Reduction Rating (NRR).
