Jinlang is a veteran French audio company, the development of beryllium units has made its audio products famous, widely used in Renault, Peugeot and other car brands, is one of the world's best high-fidelity speaker brands. After devolution of beryllium unit technology into the field of headphones, the first product, Utopia, won the 2016 CanJam Best of Show Award. The 80 ohm impedance may seem very friendly, but it is too sensitive, and the control of the headphone amp is extremely demanding. If the combination is reasonable, the scalpel-like detail analysis ability is fully displayed under the excellent sound source, and when it is not used well, it often damages the hearing sense like a fist of seven wounds. Audio Head also mentioned in the review, "Utopia's midrange is extremely detailed, and the performance of the high and low ends is even higher than expected, but if the quality of the song is not good, the amplified impurities will often backfire and affect the listening experience." "At present, the domestic price is about 28,000 yuan, and the channel spot is generally less. The sub-flagship EARAR only uses an aluminum-magnesium alloy diaphragm, with a slight compromise in quality, but the rendering of the mid-frequency is more flavorful, the sound bottom is hard and full of energy, and the vocals are full and thick, which is completely different from the romantic and delicate French mood, and the sensitivity of ELEAR can reach 104dB, even if it is matched with a portable sound source, it often does not lose its charm, and the domestic price is about 6000 yuan.
