Gold Type
Yellow Gold (Industrial Flash Plating)
Weight
2.0 - 5.0 grams (Total component weight)
Description
This is a standard 3.5mm Tip-Ring-Sleeve (TRS) audio connector, commonly used for headphones and auxiliary cables. It features a decorative and functional gold flash plating over a base metal (likely brass). The plating serves a dual purpose: providing a premium aesthetic and enhancing corrosion resistance for better electrical connectivity.
Key Features
Triple-contact TRS design (Tip, Ring, Sleeve) with two insulating black spacers; tapered tip for easy insertion; industrial yellow gold plating.
Color & Finish
Vivid rich yellow; industrial polished finish with visible surface patina and micro-scratches from insertion wear.
Hallmarks & Stamps
None visible; industrial components of this type rarely carry precious metal hallmarks.
Dimensions Estimate
3.5mm diameter; approximately 15mm-20mm in length for the plug section.
Gemstones & Inlays
None; features two black plastic/polymer insulating rings to separate Tip, Ring, and Sleeve signals.
Clasp & Closure
None (Friction-fit insertion mechanism for female audio ports).
Chain & Links
Not applicable; solid brass core construction cylindrical rings.
Craftsmanship Details
Precision lathe-turned brass or copper alloy with automated electroplating; consistent tolerances for standard audio jack compatibility.
Authentication Indicators
The 'gold' color is characteristic of industrial electroplating rather than solid gold alloy; consistent weight-to-volume ratio for brass; lack of hallmarks for 24K items.
Origin & Maker
Generic Industrial Manufacturer (likely East Asian mass-production).
Era & Period
Contemporary (Standardized audio technology circa 1950s-present; this specific unit appears modern).
Age Estimate
Likely manufactured within the last 5-10 years based on oxidation patterns.
Cultural Significance
Iconic symbol of the analog audio era and consumer electronics; ubiquitous in music culture until the rise of wireless Bluetooth technology.
Condition Notes
Good; shows visible wear on the contact rings (scuffs) indicating frequent use in an audio jack. Some oxidation/tarnish visible on the upper sections.
Value Estimate
Melt Value: Negligible (less than $0.01 USD in gold content); Market Value: $0.50 - $2.00 as a functional electronic component.
Care & Maintenance
Clean with high-percentage isopropyl alcohol to remove oils; avoid abrasive polish which will strip the thin gold plating; store in a dry environment.

Interesting Facts
Gold is used in electronics because it is a highly conductive metal that does not oxidize or tarnish as easily as copper or silver, ensuring a clean audio signal over time.
