AAW A3H+ LUX Triple-Driver Universal IEM

Tuning

Four Voicings, One Switch

A small switch on the shell changes how the crossover loads the woofer and armature paths, so the whole voicing moves. No app, no cable to swap, no EQ.

Vocal brings the midrange forward for speech, worship and vocal monitors. Normal is the balanced reference. Vocal+ adds presence and articulation without sharpness. Bass gives the woofer more weight.

Drivers

NOVA Up Front, Graphene Down Low

Each driver has its own band. AAW’s NOVA open-vented armature sits deep in the nozzle, close to your eardrum, which removes the pressure loss and tube resonance of a conventional tubed armature. It carries the voice and the treble.

A precision armature fills the upper mids, and the 10 mm graphene woofer, thin and rigid, is filtered to the low band for natural sub-bass and punch. A 3-way passive and acoustic crossover keeps the handoffs in time and in phase.

Enclosure

Machined Aluminium, Replaceable Faceplates

The shell is precision CNC aluminium: dense, durable and smooth against the ear for long sessions. AAW modelled the driver, nozzle and chamber geometry digitally, through hundreds of iterations, to settle the phase and the response.

The faceplates are replaceable, so the look can change while the sound stays the same.

Epsilon Cable Included

A3H+ LUX comes with our Epsilon UPOCC copper cable, 1.2 m long with low microphonics and 0.78 mm 2-pin connectors. Choose the player plug when you order: 2.5 mm or 4.4 mm balanced, or 3.5 mm single-ended.

The sockets are standard 2-pin, so A3H+ LUX also takes any of our 2-pin upgrade cables.

The tip is part of the tuning

Seal & Comfort

Clear Flange, Teal Bore

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

Size Tray Within Reach

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.

A3H+ LUX Triple Driver Hybrid Universal IEM

The IEM is well made with aluminium enclosure and the cable is good quality Epsilon. It is a very interesting IEM with 4 options of sound signature through switching by a mechanical switch. It has been a great experience for me. So far, I am enjoying the sound signature option in ‘Bass’ setting.

Quite impressed

It's been days testing the AAW A3H+ with my old but reliable Lune MKV cable and I'm impressed. Before the A3H (and now the A3H+), I had the Ultimate Ears TripleFi 10Pro and ended up missing the powerful bass from the UETF10P when I stepped up to the A3H but ended up liking the A3H because it was a massive improvement in every other area. That is...until I got the A3H+. This one improves upon the A3H in the mids and lows massively. It's clearer and the bass is definitely way more than I expected. I even had to lower the bass a bit using an Equalizer because it's that much more powerful than A3H's. It'll take a while getting used to these improvements but I do not regret at all getting the A3H+. I now coupled the A3H with the Nyx BT5 cable. Using both units with SpinFit CP145 eartips. I highly recommend it.

Beautiful iem. Have not ready burn in but from first listening, it is quite balanced iem.

Soundstage, Punch, Fit, Warmth and Clarity

Now in my 70's I've traded my audiophile ways in for the convenience of MP3s and flac files played on MP3 players... I realize there's a dropoff in musical info and I can hear the difference, but the convenience takes precedence, so I try to make up for it with using quality players such as Cowon Plenue players and IEMs such as the old Audeo PFE 232 and what had been my most recent phones, the Shure SE535. Having never been satisfied with the Shures but so regretful the Audeos are no longer made, I decided to finally try something from Null..... The A3H has been amazing..... My reaction to its greatest attributes are in the title, SOUNDSTAGE, PUNCH, FIT, WARMTH, AND CLARITY. Soundstage is what hit me first.... Not since my electrostatic days have I been able to experience such a defined soundstage... I'm hearing instruments and their location on the stage like I've not heard before, and discovering instruments I had forgotten were there when I listen to my old standby teest songs from the audiophile days... it's quite startling to hear even from an MP3. Of course the info has to be there in the first place but if it's on the MP3, you'll hear it like never before thru these.... And though I'm not really a bass centric listener as so many are (I concentrate on midrange where voices live), it's amazing how the A3H brings out the punch in drum lines and bass lines without overemphasizing... AS far as fit, I suspect what the A3H does for fit is not unusual for many, but when compared to the way the Shures fit in my ear, I was surprised at how easily these seal while lying flat in the ear.... Love it! And as far as my midrange, where there's where I experience the warmth of vocals and clarity is across the board.... I couldnt' be happier with my purchase... One other attribute I've discovered that differentiates these from my prior phones... It's extraordinarily exciting to hear just how much better these sound the louder you play them... That might sound ...

Impressed

Came from an 11 year old UE10 TripleFi with the Lune Mark V cable. These have a very different sound signature. Soundstage is definitely clearer and instrument separation is in another league. These don't need that much help from an equalizer like my UE10. This is a keeper and feels (as it sounds) very high quality in your hands.

Better then most other $400 plus priced IEMs

These IEMs sound very lively. Alot more power and dynamics compared to something like a shure 425. The separation is really good. The bass response is really nice. The bass sounds full and not too muddy or over-powering. The highs are really crisp, and it is very prominent in certain mixes, though to my ears, it's not to Sharpe nor irritating to the ears. Decent mids. Not muddy or harsh. Really satisfied with them. And they look really cool too.

AAW A3H

Great, balanced sound. Great build quality. Beautiful design. Couldn't ask for more, and the Lune cable was a nice touch.

A3H Universal

Well Worth it, good value Reference Grade !

A3H Universal

Although A3H come with 10 mm dynamic driver, the bass is not overpowered like some hybrid IEM. Because of this, the overall sound signature is clear and detail. It still got good bass that pure balanced armature IEM do not have, but I personally prefer a but more as I love band sound.

Questions

Good to know

What does the tuning switch do?

It changes how the crossover loads the woofer and armature paths, giving four voicings on one monitor: Vocal for speech, worship and vocal monitoring; Normal as the balanced reference; Vocal+ for more presence and articulation; Bass for a fuller low end. The graph above shows all four.

What is the driver configuration?

Three drivers: a NOVA open-vented armature for vocals and treble, a precision balanced armature for the upper mids, and a 10 mm graphene dynamic woofer for bass, joined by a 3-way passive and acoustic crossover.

Who is A3H+ LUX for?

Musicians on stage, worship teams and emerging artists, and anyone who wants one monitor that can change its voice for different music. At 12 Ω it plays well from a phone dongle, a DAP or a desktop amplifier.

Which cable fits A3H+ LUX?

A3H+ LUX has 0.78 mm 2-pin sockets. Choose Standard 2-pin (0.78 mm) on any of our cables; see the AAW cable guide.
