Meze Rai Penta are 5 driver, Hybrid design earphones with a custom designed Silver plated copper Litz mmcx cable. Rai Penta were 3 years in the design process, featuring a machined aluminum shell with a smooth, ergonomic shape for a great fit.
Beautiful sound quality with no sibilance and a full deep bass response.
Headfonia.com: added to best IEM list: Rai Penta is detailed, precise and transparent and with its neutral yet musical tuning the Rai Penta will win over many hearts. Making a correct sounding hybrid is hard but Meze makes it seem oh so easy.
