EarSonics SM3 universal triple driver earphone is designed with the most demanding audiophile in mind, offering equalizer: tight controlled bass (very good quality and quantity) and very good mids. The SM3 pushes further the limits already achieved with universal fit in-ears. Increased venting produces a tighter low end and the wider sound image features and excellent treble. New proprietary silicon tips guarantee very good sounding reproduction, good comfort and also good sound isolation. The SM3 don’t sound like most other IEMs, they have their own unique sound!
