Etymotic ER4XR Extended Response Earphones
The ER4XR is a highly accurate and compact in-ear monitor, featuring a single balanced armature (BA) driver. The anodized aluminum shells, which are CNC machined with tight tolerances, are paired with a durable and replaceable cable. Known for its strong passive isolation, the ER4XR offers 35-42 dB of noise reduction, making it an ideal choice for audiophiles seeking an immersive audio experience.
The right and left channels of the ER4XR are matched within 1dB across frequencies, ensuring a consistent and enjoyable listening experience. Compared to the reference model, the ER4SR, the ER4XR offers a "fun" sound signature with added bass.
The ER4SR is ideal for sound engineers and audiophiles who prefer a flat and accurate sound reproduction, while the ER4XR caters to those who enjoy a bit of extra bass presence. The frequency response graphs of the ER4XR are designed to deliver a perceptibly flat frequency response that compensates for the resonance in the ear canal. This target frequency response was developed by Etymotic based on over 20 years of human hearing and acoustics research.
Each ER4SR and ER4XR comes with a channel-matching compliance graph, ensuring exceptional accuracy and precision in the mid to high frequencies, with a bit of extra presence in the lower end. The sleek, anodized, and laser-etched aluminum body of the ER4XR, combined with the braided and reinforced 5-foot detachable cable with custom MMCX connectors, provide a durable and visually appealing design.
The ER4XR's high-performance balanced armature drivers are precision-matched to within 1 dB, delivering uncompromising accuracy and consistent performance. With a maximum output of 122 dB and 35-42 dB of noise isolation, the ER4XR offers an immersive and distraction-free listening experience, making it a top choice for audiophiles and sound professionals alike.
