This is a genuine ReSound replacement receiver wire for the ReSound Vivid Stratus hearing aid, designed exclusively for the left ear. The "L3" designation refers to the size 3 wire length (32.3mm), suitable for a deeper or longer ear canal fit. This is a receiver-in-canal (RIC) style component — the small speaker unit that connects via a thin wire from the hearing aid body worn behind the ear to a dome or ear tip seated inside the ear canal.

Receivers are color-coded for easy identification: blue indicates the left ear. The wire length number (3) and millimeter measurement (32.3mm) help audiologists and hearing care professionals select the correct size for a comfortable, accurate fit. Replacing worn receivers can restore consistent audio performance and sound quality in your hearing aid.

This item is compatible only with the ReSound Vivid Stratus hearing aid sold at Costco Hearing Aid Centers. It is not interchangeable with other ReSound models. Installation is typically performed or guided by a Costco hearing care professional.
