Sony 5-048-504-21 Noise Isolation Ear Piece

Product Description

The SONY 5-048-504-21 is a noise isolation ear piece designed as a replacement component for compatible Sony wireless earbuds. This part provides the physical seal between the earbud driver housing and the ear canal, directly supporting passive noise attenuation alongside active noise cancellation circuitry in the host device. Replacement of worn or damaged ear pieces restores fit integrity, which is critical to both acoustic performance and noise isolation effectiveness. This is a Sony OEM accessory part, typically installed by the end user or a consumer electronics technician performing a component-level repair.

The 5-048-504-21 ear piece is referenced in Sony parts documentation for the WF-1000XM5 true wireless earbud model. It is suited for situations where the original ear piece has torn, degraded, or been lost, and a like-for-like OEM replacement is required to maintain the designed acoustic seal and wearing comfort of the earbud.

Key Features

• OEM Sony replacement ear piece for the WF-1000XM5 earbud platform
• Designed to maintain passive noise isolation seal at the ear canal interface
• Direct factory replacement for worn, torn, or missing ear pieces
• Supports the acoustic performance specifications of the host earbud device

Compatibility

Compatible with the Sony WF-1000XM5 true wireless earbuds as stated in the source product documentation.

Installation Notes

Installation is typically performed by the end user or a consumer electronics repair technician without specialized tools. Power down and place the earbuds in their charging case before handling internal or external components. Align the ear piece opening with the driver nozzle and press firmly until fully seated. Inspect the seal around the nozzle perimeter to confirm no gaps that would compromise noise isolation performance.
