AAW Z05 is a universal-fit hybrid in-ear monitor from AAW (Advanced AcousticWerkes), worn with standard ear tips. It comes with our Ethos Ultra cable and its 3.5 mm, 4.4 mm and USB-C DAC plugs.
A 10 mm dynamic woofer and four balanced armatures, with a TwinCore switch that moves the voicing between Blue (fuller, calmer) and Red (tighter, brighter). Same drivers and tuning as Z05 AuAg Launch Edition, with ice-crystal titanium alloy faceplates and a USB-C DAC you can tune with parametric EQ.
AAW Z05
Z05 is AAW’s compact five-driver hybrid: a 10 mm dynamic woofer, four balanced armatures and a TwinCore switch that moves the whole voicing between two moods.
It has the same drivers and tuning as the gold-and-silver AuAg Launch Edition, wears ice-crystal titanium alloy faceplates, and comes with our Ethos Ultra cable, whose USB-C plug is a complete DAC with parametric EQ.

Inside Z05
Scroll to take Z05 apart. Under the faceplate sit two balanced armatures, mid and super-high, above the 10 mm dynamic woofer.
The TwinCore switch sits in the side of the shell, the 2-pin socket in its top. Acoustic filters and a fine dust mesh guard the nozzle, and the LiquidMorph tip seals it.
TwinCore
TwinCore is a physical two-position switch on the side of each earpiece, with a red and a blue dot marking its two positions. It changes how the crossover loads the dynamic woofer and the armatures, so the whole voicing moves, not just a bass shelf.
Blue gives a fuller low end, calmer upper harmonics and an easy centre image for long albums. Red tightens the bass outline, brings clarity forward and adds cymbal air.
Drivers
A 10 mm PET-diaphragm dynamic woofer carries the bass, with two mid and two super-high balanced armatures for vocal edge and air, joined by a 3-way passive crossover.
AAW’s Bass-Flow vent balances the pressure in your ear canal and controls the air behind the woofer, so the low end hits without pushing the midrange.
Finish
The faceplates are ice-crystal titanium alloy, with an iridescent crystal pattern in turquoise, pink and lavender that shifts colour as the light moves. Z05 and AAW are marked in gold on glossy black 3D-printed shells. The crystal pattern differs from piece to piece, so no two pairs look quite the same.
The compact universal body sits close in the ear, and the cable runs over the ear to keep it settled.
In the box
Z05 comes with Ethos Ultra, our coaxial cable with a 5N single-crystal copper conductor, a silver-plated copper shield and a Kevlar core, ending in 0.78 mm 2-pin connectors.
The player end screws off: 3.5 mm, 4.4 mm balanced and a USB-C DAC plug are all included, so phone, DAP and desktop are covered on day one.
Seal & Comfort
With a dynamic woofer, the seal is not a footnote. When the tip sits right, bass weight, vocal centre and left-right balance stop changing every time you move.
LiquidMorph tips pair a rounded, transparent silicone flange that settles without feeling bulky with a teal inner bore that stays stable, so the low end does not collapse when the shell shifts.
Fit
The tips come in a tray, sorted by size, so you can check them before a long session instead of digging through a loose bag of parts.
The right tip is often the difference between good and there it is.
USB-C DAC + Parametric EQ
The Ethos Ultra USB-C plug is a complete 32-bit / 384 kHz DAC with a parametric equalizer built in. Choose Blue or Red on the TwinCore switch for the broad shape, then fine-tune Z05 with the Null Audio PEQ app and write it to the DAC. Your tuning plays the same on iPhone and Android.

Tuning needs the Android app, or Chrome or Edge on a computer; iPhone browsers can’t connect to the DAC. Once written to the DAC, your EQ plays on iPhone too.

The look, the cable and the price. Drivers, TwinCore tuning and specifications are the same. This Z05 has ice-crystal titanium alloy faceplates on black shells instead of the gold-and-silver launch finish, and comes with our Ethos Ultra cable, which adds a USB-C DAC with parametric EQ.
It is a physical two-position switch on each earpiece that changes the crossover loading between the dynamic woofer and the armatures. Blue is fuller and calmer for long sessions; Red is tighter in the bass and more forward and airy. Set both earpieces to the same position.
Yes, with USB-C iPhones (iPhone 15 and later), iPads and Android phones, and with Windows, macOS and Linux computers. No driver is needed. To change the EQ, use the Android app or peq.null-audio.com in Chrome or Edge on a computer; once it is written to the DAC, it plays on iPhone too.
No. The USB-C DAC plays as soon as you plug it in, and the 3.5 mm and 4.4 mm plugs work like any wired cable. The app is only for tuning the parametric EQ.
Yes. At 110 dB and 12 Ω it runs well from the included USB-C DAC, a dongle or a DAP. A source with output impedance below 1 Ω and low or medium gain keeps the noise floor down.
Yes. Z05 uses standard 0.78 mm 2-pin sockets, so it takes any of our 2-pin cables.
