AZLA / TRINITY Champagne Gold AZL-TRINITY-ST-GLD

The AZLA ‘TRINITY’ (Trinity), based on the concept of the trinity of fitting, sound quality and cost performance, is a newly developed super-entry concept model aiming for the best sound quality in its class, allowing you to experience a glimpse of the world and sound quality of expensive Hi-Fi wired earphone

■[A game Changer for All Music Lovers] Super-entry for a high sound quality experience
・『TRINITY』is a super-entry concept model, newly developed after more than a year of trial and error to achieve the best sound quality in its class, in the hope that more people can experience a glimpse of the world of expensive Hi-Fi wired earphones and their sound quality. Under the slogan “A game Changer for All Music Lovers”, TRINITY embodies the trinity of fitting, sound quality and cost performance. The name TRINITY was given with the aim of creating a new generation of wired earphones that embody the concept of the trinity of fitting, sound quality and cost-effectiveness.

The ‘Advanced ARD Driver’ with a three-layer diaphragm structure that suppresses split vibrations
- The driver at the heart of the sound quality is equipped with an 8 mm diameter ‘Advanced ARD Driver’. The developmental ARD is a special dynamic driver that uses a 46µ-thick three-layer structure diaphragm with an ultra-thin PU+PEEK composite membrane diaphragm sandwiched between two resin layers, and an external magnet that efficiently obtains magnetic force by placing a doughnut-shaped magnet outside the voice coil.

The TRINITY is a driver that is the cornerstone of sound quality, and has been tuned to the highest level in its class through repeated trial and error to bring out the full performance of the driver. Distortion has been thoroughly eliminated from ultra-low to ultra-high frequencies, and clear sound with low incidental sound and a high S/N ratio has been achieved. The result is a sound with subtlety and depth, achieved by focusing on bringing out the best in each material. In the bass range, the internal loss has been optimised with the aim of achieving “visible bass” by utilising the features of the driver to achieve high low frequency resolution and a sub-bass (super-heavy bass range) that can be felt. The sound does not peak or distort even when the volume is turned up, and does not break down.

Premium silicone earpiece ‘SednaEarfit T’ developed in a dedicated shape
- In order to improve the fitting of TRINITY, which is not an in-ear earpiece type, and to maximise the S/N ratio by sound insulation, premium silicone manufactured by KCC SILICONE is used and developed in a dedicated shape. Includes 4 sizes of SednaEarfit T earpieces (S/MS/M/L *M size initially fitted). By adopting a unique tapered fit structure where the umbrella part is curved and becomes thinner towards the tip, the sound insulation is more accurate while reducing pressure on the ear, and the sound from the main body of the earphone is transmitted straight to the ear in the shape of an internal horn. A carrying pouch is also included for carrying them around.

The TRINITY line-up consists of two types: a 120cm Standard type with 3.5mm 3-pole L-shaped plug and a 150cm USB-C type with USB Type-C plug and high-sensitivity microphone. The USB-C type is UAC1.0 specification and supports up to 96KHz/24bit high-resolution playback, Switch/Switch 2 and PS5.
