Weight
1.5 to 2.5 grams
Description
This is a 3.5mm TRRS audio connector, commonly used for headphones and mobile communication devices. While it possesses a brilliant yellow gold-colored aesthetic, its core function is electrical conductivity rather than jewelry or bullion investment. The gold plating is applied to prevent oxidation and ensure a stable, low-noise connection for analog audio signals.
Key Features
Triple-band insulator design (TRRS), tapered tip, and exposed internal solder terminals with residual wire and adhesive/insulation remnants
Color & Finish
Yellow gold tone with a high-polish reflective surface; significant scratching and debris present on the upper terminal
Hallmarks & Stamps
None; electronic components of this nature do not typically carry precious metal hallmarks
Dimensions Estimate
3.5mm diameter at the pin; approximately 15mm - 20mm in total length
Gemstones & Inlays
None; features two black plastic/polymer insulating rings to separate audio channels
Clasp & Closure
Friction-fit plug mechanism for audio ports; the upper section shows raw solder pads for wire attachment
Chain & Links
N/A; rigid cylindrical body with a stepped-tip design for TRRS (Tip-Ring-Ring-Sleeve) configuration
Craftsmanship Details
Precision-machined metal lathe work with automated electroplating; basic industrial quality.
Authentication Indicators
The 'gold' appearance is highly uniform and lacks the deep luster of solid gold; the presence of industrial insulation and solder identifies it as a functional component rather than jewelry.
Origin & Maker
Generic industrial manufacture; likely produced in an electronics facility in East Asia
Era & Period
Contemporary / Digital Age (Late 20th century to present)
Age Estimate
Circa 2000-present; modern mass-produced component
Cultural Significance
Symbolizes the era of portable personal audio and the transition from analog to digital mobile technology.
Condition Notes
Poor / Salvage condition. Significant wear, scratches on the barrel, and residual debris (hair, dust, and solder) on the terminal end suggest it has been removed from a device.
Value Estimate
Negligible market value. Melt value is $0.00; retail value for a new component is approximately $0.50 - $2.00.
Care & Maintenance
Not intended for jewelry care; keep dry to prevent corrosion of base metals under the plating. Clean contacts with isopropyl alcohol if used for audio functionality.
Similar Items

Interesting Facts
Gold is used in electronics because it is highly conductive and does not tarnish, which preserves the quality of audio signals over time compared to silver or copper.
