HiFiGo TRN BAX Four-Unit Flagship Headphones: A Flagship Quad-Driver Hybrid Earphone with Stunning Electrostatic Performance

The HiFiGo TRN BAX is an exciting new flagship in-ear monitor that combines electrostatic, balanced armature, and dynamic drivers for stunning audio performance. As TRN’s first electrostatic hybrid earphone, the BAX aims to deliver unparalleled clarity and detail across an extremely wide frequency range.

Overview

The HiFiGo TRN BAX Four-Unit Flagship Headphones utilizes a quad-driver configuration consisting of two electrostatic tweeters, a Knowles balanced armature handling mids, and a 10mm dual-magnet dynamic driver for the low end. This advanced hybrid driver design allows the BAX to excel in transparency, soundstage, and resolution while maintaining powerful yet accurate bass.

Key Features:

• Quad-driver hybrid configuration with dual electrostatic tweeters for pristine treble
• Customized Knowles balanced armature for full, sweet mids
• 10mm dual-magnet dynamic driver delivers impactful yet accurate bass
• Semi-open design for pressure relief and reduced distortion

Electrostatic Performance

The two electrostatic tweeters are the real highlight, providing silky smooth and airy treble extension up to 40kHz. According to HiFiGo, the BAX exhibits better sensitivity in the 20-40kHz region compared to typical balanced armature earphones. This results in stunning realism for instruments like pianos and strings.

Customized Balanced Armature

In the midrange, HiFiGo equipped the BAX with a customized Knowles balanced armature tuned for a fuller, sweeter vocal presentation. This tailored balanced armature complements the ultra-detailed electrostatic tweeters beautifully.

Powerful Dynamic Driver

Handling the low frequencies is a capable 10mm dynamic driver featuring a dual-magnet circuit design. It provides impactful yet controlled bass to balance out the BAX’s airy top end.

Semi-Open Design

The included semi-open balanced pressure relief ear tips help optimize the performance of the hybrid driver configuration by alleviating air pressure issues inside the ear canal. This enhances clarity and reduces distortion for fatigue-free listening.
