SureFire EP4 Sonic Defenders Plus


If you’re looking for a minimalist and comfortable in-ear protection, look no further. The Surefire EP4 Sonic Defenders are a great option, offering a 24-dB noise reduction rating when the filter caps are inserted. The filter cap can be opened to allow for clearer sound without having to remove the unit from your ear as well.

The silicone tips paired with the Earlock retention rings makes for a comfortable and adequate seal while preventing them from accidently falling from your ear.
