The ER2SE earphones from Etymotic are equipped with powerful dynamic drivers and deliver clear, accurate sound. The well-fitting earplugs provide an isolation of outside noise of 35 - 42 dB. This way you can hear all the details of the music undisturbed, regardless of whether you listen to loud or soft music. The ER2 series has been fine-tuned for low tolerances to achieve high playback accuracy. This allows you to experience the music like at a live concert. The metal housing of the ER2SE is very slim and fits comfortably in all ear canals, even the narrowest. The anodized blue surface looks noble and is particularly robust. Various earmoulds made of silicone and foam ensure a firm fit in the ear and good isolation from external noise. This ensures high wearing comfort and an optimal sound flow. The 1.2 meter long, amplified earphone cable can be easily replaced if necessary thanks to the MMCX connection.
