With a 32-ohm impedance, 118dB sensitivity, and 3.5mm mono plug, it is rated for users with mild and low gain hearing loss in hearing assistance deployments.

Product Description

The EAR 022 surround earphone positions itself around the ear using an external hook design, resting comfortably without inserting into the ear canal. This makes it a practical option for users who find in-ear earphones uncomfortable or impractical during extended events. Its 118dB sensitivity at 1kHz is among the highest in the Williams Sound earphone range, delivering strong output even from low-volume receiver settings. The 23mm driver provides clear mid-range reproduction appropriate for speech intelligibility in FM and IR assistive listening applications. At 15 grams with a 39-inch cord and 3.5mm mono plug, the EAR 022 is suited for daily distribution from a venue carry case. The 30mW maximum power input is appropriate for the output levels of Williams Sound portable FM and IR receivers. This earphone is rated for mild and low gain hearing loss classification, and is recommended for FM receivers and select IR receivers.
