10mm dual magnet dynamic driver
TRN STM comes equipped with dual magnet dynamic drivers. Dual magnet gives higher magnetic flux, which gives high sensitivity and low impedance increases energy efficiency and transient response.
Customized 30019 balanced armature drivers for better resolution and fidelity
TRN STM utilizes customized 30019 balanced armature drivers for a clear and open treble extension. Balanced armature uses "armature + drive rod" that reproduces high-frequencies that diaphragm-based dynamic driver could not achieve and give faithful sound reproduction without losing micro details.
The high-quality alloy housing plate
Aluminum alloy front plate combines with resin housing for rigidity and toughness.
Electronic crossover for exceptional sound quality throughout the entire frequency band
Exquisitely designed electronic crossover unleashes the full potential of every driver unit, both the balanced armature driver and dynamic driver, giving utmost sound quality across the frequency band.
Sharply-focused and insistent on using better technology and professional tuning
The frequency response is smooth and coherent. Rich in vocal texture with a balance of harmony in every subtle nuance. Optimal bass reproduction with an effortless transient attack, precision, and low distortion.

Ergonomically-designed ear hooks
Over-the-ear ear hooks for maximum comfort and stability allow you to focus on your music while performing daily activities. At the same time, such wearing method reduces microphonics transmit to the earpieces, thus less interference to your music enjoyment.
Newly improved 0.75mm Type-C connectors
Gold-plated contact pins
From reviews and customers feedback, it is known that the new and improved Type-C connectors can effectively protect the contact pins from accidental breakage, which gives longevity and better wearing stability to the users.

Plug cable connector to the earpiece.
Insert until the earpiece is secure. To remove, grab the earpiece and cable connector, pull straight.
How to properly fit an IEM
Identify the left and right earpieces.
Bring hand overhead and grasp the top of the ear.
Pull the ear up and out to straighten the ear canal.
Loop memory wire over-ear and insert earpiece into the ear canal.
Be sure to slide the ear tip far enough until it seals inside your ear.
The quality of sound and isolation depends on how well the ear tips seal. If lacking bass, check the tightness of the seal between ear tips and your ears or try other ear tip sizes.
