AAW ATH 6-Driver Hybrid Custom In-Ear Monitor is a custom-fit in-ear monitor from AAW (Advanced AcousticWerkes), shaped from your ear impressions or a 3D scan of your ears. We take impressions at our studio in Singapore, and every custom IEM comes with a Null Audio cable.
ATH features a cutting-edge hybrid architecture design consisting of FIBAE technology to bring flat impedance and corrected phasing to an isobaric dual dynamic driver-based system. ATH utilizes advanced Nozzle-less Open Vented Armature (NOVATM) Driver coupled with 3 mid-range balanced armature drivers housed in a digitally designed acoustic chamber.
ATH’s faceplate design employs a new technique called Electroless Immersion Gold, the unique process allows us to achieve complex designs over tiny acre of space.
Flat Impedance Balanced Armature Earphone (FIBAE™) technology is the world's first, revolutionary, In-Ear Monitor design providing flat impedance and phase. By changing Balanced Armature driver character from inductive to resistive Custom Art solved one of the oldest problems in the industry – dependence on output impedance of sound source for correct earphone output. With FIBAE™ technology your earphones will always perform best from any DAP. FIBAE is graciously licensed to AAW by Custom Art Poland.
In this hybrid structure, we choose to use a specially designed armature driver with an open front acoustic vent and embedded it deep into the ATH's 3d printed nozzle. The proximity to the user eardrum eliminates sound pressure decay and any unwanted resonance in a typical tubed balanced armature design.
The 8mm dual isobaric woofer is equipped with dual diaphragms and high strength neodymium magnets. The isobaric design offers reduction in low range THD and higher sound pressure output in comparison to typical dynamic woofers. By further utilizing acoustic filtering technique, it is to only function in minimal overlapping frequency range as opposed to the balanced armature drivers. It pushes the bass performance to a new level in the ATH while not overpowering the rest of the spectrum.
The integration of a newly developed eBFC system allows users to select 4 distinctive sound signatures, rendering ATH one of most versatile performer in handling different sources and use case scenarios. The 4 settings not only differ in sound signature delivery but also vary in impedance and sound pressure level.

ATH is tuned with a vigorous and lively sound signature in mind, it offers a natural but hard-hitting sub-bass, which you will never find in a full balanced armature setup. FIBAE mid-woofer driver delivers smooth and precise mids. The dedicated NOVATM driver offers crystal clear details in the upper mid and high range. The treble extension is well controlled to provide a non-fatiguing listening experience. ATH delivers expansive headroom, high fidelity with extreme dynamic range and fast transient responses.
Suitable for band performances, performing artists, worship events, audio engineering and anybody who appreciates exceptional listening experience.
The lead-time for this product is about 4 weeks from the date we receive your ear impressions or 3D scan.

Upgrading the cable? Most AAW IEMs use a 0.78 mm 2-pin socket. See which Null Audio cables fit AAW IEMs.
Choose your options on this page, then get ear impressions made. In Singapore we take impressions at our Playfair Road studio for SGD 50, by appointment. From overseas, send us 3D scans (STL files) of your ear impressions or ear canals. See how to order custom IEMs.
Every custom IEM comes with a Null Audio cable, and you can upgrade to a higher-tier cable when you order. AAW customs use recessed 0.78 mm 2-pin sockets; see the AAW cable guide.
Refits are free within 30 days of delivery. For overseas orders, return shipping is charged separately.
The ATH has a 1-year warranty. Custom IEMs are made to your ears, so they can’t be returned for a change of mind; quality problems are covered by the warranty. See shipping and returns.
Custom IEMs are built to order and made in about 4 weeks after we receive your ear impressions or scan.
