According to the experts at Etymotic Research, the company’s ER20XS high-fidelity earplugs allow people to hear loud music better. At high levels, the human ear overloads and distorts, “smearing” the details of the music. “Industrial” earplugs alter the fidelity of the music by reducing high-pitch sounds more than low-pitch sounds. ER20XS earplugs have a balanced response and reduce the sound to an optimal range that allows the ear to process sound without distortion and the listener then hears the music more clearly.
The Galaxy Audio EB4 In-Ear Monitor Ear Buds employ single titanium drivers for high-fidelity with extended bass and a full 20Hz~20kHz (+/- 3dB). Heavy-duty cabling and aluminum construction provide durability for stage use. The lightweight design and three Silicon sleeves (small, medium, and large) provide a comfortable fit. EB4 ear buds come with a standard 3.5 mm jack.
