I thank my dear friend, Bryan, aka Gnarlsagan, for providing me with an opportunity to analyze this nice piece of IEM.
Originally priced at $79, HiFiMAN RE-0 is a budget IEM, known to outperform some of the top-notch IEMs in the market. While other high-end products of the brand, such as RE-262 and RE-272, are finely engineered to meet the general criteria of Hi-Fidelity in headphones, it is considered that RE-0 also comes very close.
PRO: Overall very linear. Distortion-free. Left & right channel matching is excellent. Due to its linear, yet high impedance value, it is almost impossible to alter the sound of RE-0 electrically.
CON: Slightly peaky in the upper frequency range due to resonances.
