This is an OEM-sourced component used to restore a proper acoustic seal and secure fit when the original ear tip is lost, torn, or worn. A correct-fitting ear piece directly affects sound isolation and bass response, making this a functional repair part rather than a cosmetic one. Licensed HVAC technicians do not typically service consumer electronics, so installation is generally performed by the end user or a consumer electronics repair technician.\u003c\/p\u003e\u003cp\u003eThis ear piece is sized for medium fit applications and is identified in Sony parts documentation as the long variant, which affects how deeply it seats in the ear canal. It is listed as a compatible part for the Sony MDR-XB50BS wireless sport earphone line. Consumers and repair shops sourcing replacement ear tips for that model should confirm the size designation before ordering, as Sony typically offers small, medium, and large variants.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLong-style ear piece providing a deeper canal fit compared to standard-length tips\u003c\/li\u003e\n\u003cli\u003eMedium size designation for average ear canal fitment\u003c\/li\u003e\n\u003cli\u003eOEM Sony replacement part for accurate fit and material consistency\u003c\/li\u003e\n\u003cli\u003eCompatible with MDR-XB50BS as listed in Sony parts documentation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eListed as a replacement ear piece for the Sony MDR-XB50BS wireless sport earphone.

Power off or disconnect the earphone before handling. Align the ear piece opening with the nozzle of the earphone driver housing and press firmly until seated. Do not use adhesives or solvents, as these can damage the silicone material and the driver housing finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: Medium (M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type\u003c\/strong\u003e: Ear Piece \/ Ear Tip\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SONY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4-543-905-31\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SONY","offers":[{"title":"Default Title","offer_id":51201495171378,"sku":"4-543-905-31","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307149864.jpg?v=1779697333","url":"https:\/\/voomisupply.com\/products\/sony-4-543-905-31-ear-piece-long-medium-headphone-part","provider":"Voomi Supply","version":"1.0","type":"link"}
