Newly Upgraded 5-Pin Replaceable Audio Jack

The TRN-Sea Serpent is a premium audio cable crafted with a blend of copper and silver wires, offering superior sound quality and clarity. Its newly upgraded 5-pin replaceable audio jack ensures accurate and stable transmission of audio signals, providing an immersive listening experience.

High-Quality Cable Construction

Carefully selected materials ensure exceptional quality in the TRN-Sea Serpent. The cable features a four-strand copper-silver mixed construction, enhancing sound richness and full-frequency resolution. Each signal path incorporates an 89-core Litz wire construction with high-purity oxygen-free copper and silver plating, guaranteeing high-quality signal transmission.

Replaceable Audio Jack for Versatile Compatibility

Equipped with a straight-plug replaceable audio jack, the TRN-Sea Serpent offers compatibility with 3.5mm single-ended, 2.5mm balanced, or 4.4mm balanced audio jacks. Its ergonomic design ensures comfortable wearing, with an over-ear ear hook design for added stability and reduced pressure on the ear canal, enhancing long-term wear comfort.

Clear and Bright Voice Recording

Featuring a high-definition microphone, the Sea Serpent delivers clear and bright voice recordings. Its high-sensitivity electrical output responds sensitively to sound changes, ensuring clearer calls and brighter vocals.

High Resolution with Improved Detail

Experience high-resolution audio with improved detail across all frequency bands. The Sea Serpent accurately transmits fine audio details, deepening the sense of dimensionality between frequency bands and portraying a more natural and bright sound field.


The Sea Serpent requires a 5-pin jack for microphone functionality; the old 4-pin jack does not support this feature.
