Etymotic ER2 SE/XR Noise-Isolating Earphones cable not detachable This new design places allWhich ER2 is right for you? Both ER2 models, the ER2SE and ER2XR, use the same low impedance dynamic drivers. That means they are easy to drive, and no amplifier is required. The only difference between the 2 models is the tuning of the lower (bass) frequencies. The Studio Edition ER2SE is tuned to have a flat frequency response. The eXtended Response ER2XR is tuned to have an emphasized bass, adding 1 2dB to the mid bass and 3 4dB to the sub bass.
