Pros — Regulate boomy bass in some earphones; very grippy; perfect fit, hold, seal, and isolation; mould into the shape of ear canal; totally different from any other eartip.

Cons — Dirt attractors: need regular washing; can get out of shape and need to be re-shaped in hot water; not for short-nozzles iems; pricey.

Distinctive Features Best fitting of all eartips I have used; enhances vocals in many earphones.

Executive Summary

The Azla Xelastec are completely unique short-stemmed wide-bore eartips in that they provide the perfect fit through their incredible grip AND move vocals forward in many earphones.

Introduction

Azla is a company out of Korea that offers two earphones, an amplifier, and lots of different silicone eartips. Their most famous product has been the Azla SednaEarFit Original Series, consisting of four models, two of them long-stemmed, two of them short-stemmed, all of them wide-bores.

These are very popular with audio enthusiasts, typically hard to get outside of Asia, and mostly sold out. The designs are based on the analysis of almost 800 ear shapes. All Azla products are manufactured in the Republic of Korea.

Xelastec Design

Azla have recently added the Xelastec eartips to their portfolio, short-stemmed wide-bores made of German Kraiburg TPE different to any other earphone on the market.

TPE is short for Thermoplastic Elastomers, also known as thermoplastic rubbers, a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties.

Azla Xelastec

The benefit of using thermoplastic elastomers is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials [see Wikipedia].

The material is extremely grippy and also extremely deformable. The umbrella moulds perfectly into the shape of one’s ear canal. Fit, hold, seal, and isolation of the Xelastec are therefore perfect.

And when the eartips retain their deformed shape, the original shape can be restored in a bath of warm to hot water (but not too hot; rinsed off with cold water). The TPE is unfortunately a dirt attractor, but can be washed easily with water.

Azla Xelastec

In terms of earphone fit, the short stems require a certain nozzle length. The inner stem diameter of 3.6 mm is stretchable enough to fit standard 4.5 mm nozzles. All Azlas come in 6 different umbrella sizes (see size chart above) to fit any ear canal. Be aware that their sizes are unusual: Azla’s L corresponds to other company’s XL. Check your numbers before ordering.

Sound?

I typically do not give sonic descriptions of eartips, as different designs yield different results depending on earphone and individual ear canal. The Azla Xelastec are somewhat of an exception as they have a tendency to work well with more iems than other makes models in my experience.

I have not found many earphones the Xelastec did not make a difference to the better. Their risk of failure/dissatifaction is smaller, but you pay for it.

In my experience (almost 1 year of testing them), the Xelastec show the biggest improvements with V-shaped sound profiles. They move the vocals forward and therefore, passively, the bass backward, considering the human ear hears the whole frequency spectrum in context. Bass boom was decreased or disappeared altogether.

This worked well for me with the Meze RAI Solo, Shozy Form 1.4, Shozy Form 1.1, Shozy Rouge, and NiceHCK NX7 Mk3, in less so with the KBEAR Believe.

In comparison, the Azla SednaEarfit (Original Series) Light, shortstemmed, boost the bass and move the vocals back in many iems. The difference is substantial.

What KopiOkaya says

Co-blogger Larry Fulton alias KopiOkaya summarizes the main characteristics of the leading third-party eartips in his famous eartips guide, including the Azla Xelastec. His professional opinion is as follows:

Azla SednaEarFit XELASTEC
Bore size: regular
Stem length: regular
Feel: soft, grippy and sticky
Bass: 4.0
Midrange: 5.0
Treble: 3.75
Soundstage: 3.50
Vocal presence: 5.0

The most expensive eartip in my collection. Isolation is impeccable. If you love vocals, THIS IS IT! Vocal presence is extremely 3D. Best of all it doesn’t affect bass and treble. Projects soundstage a bit narrower than regular SednaEarFit.

Concluding Remarks

The Azla Xelastec are probably the best and most versatile eartips on the market – and unfortunately the most expensive. They work well with most earphones and have a higher rate of success “fixing” an iem’s sound than the competition I have tested, particularly when addressing the vocals department. Yes, they are pricey but they need to be in the “tips box” of every audio enthusiast.

Until next time…keep on listening!
