Tri-Hybrid Architecture

ACH is our second attempt at the three-tiered hybrid system following the critic acclaimed Canary Electrostatic Hybrid In-Ear Monitor. In comparison to Canary, ACH utilized a more affordable ceramic super tweeter coupled with a dynamic woofer and a patent pending NOVATM mid-high range armature driver.

Flagship performance at entry cost

Entry or Flagship? AAW design and charter our product roadmap carefully to cater different market segment and price range. We always make the best effort to fully tap on the potential of our driver combinations, regardless of their driver count. ACH brings a new era of acoustic architecture on the table and despite its competitive costing due to driver type and count. The tri-hybrid platform delivers ear catching performance at a fraction the cost of a typical flagship In-Ear Monitor.

Ceramic Super Tweeter

AAW’s proprietary ceramic super tweeter features an industrial first 7 layered piezo-electric ceramic membrane. The membrane is seamlessly integrated with the dynamic woofer, essentially form a coaxial structure as the membrane is laser welded directly onto the dynamic driver’s enclosure to ensure maximum structural rigidity and mitigate unwanted vibration.

Nozzle-less Open Vented Armature (NOVATM) Driver

In this tri-hybrid structure, we choose to use a specially designed armature driver with an open front acoustic vent and embedded it deep into the ACH’s stainless steel nozzle. The close proximity to user ear drum will eliminate sound pressure decay and any unwanted resonance in a typical tubed balanced armature design.

Ethos MKIII Silver Plated Cable

The newly upgrade Ethos cable features a multi-stranded UPOCC copper core with silver plating. In a unique bi-twisted structure coupled with ultra-flexible clear PVC jacket, Ethos MKIII brings a new level of aesthetic and comfortable user experience, while offer superior sonic performances.

Interchangeable Faceplate Design

ACH employs a user interchangeable faceplate using hex screws. Additional faceplate design and even customized designs are available for choosing.

Suitable for band performances, emerging artists, worship events and anybody who appreciates fine listening experience.

      The product I received is defective.

      The design is pretty.
      However, it is defective.
      The balance of the left and right volumes is different.
      This product is not a stereo pair matching.

      Nice Sound!

      ACH has deep bass and characteristic firm treble, head room is very large.
      In say Japanese, " Sukoshi Don Shari".
      But, Mid sound is so natural.
      So, I think, May be, Nova Driver is being good expression.
      ACH Sound is so pleasant.

      Unbittable quality and price

      I just got my ach, and it was really amazing. The most impressive thing is the highs, the ceremic twetter really sounds like the electrostatic driver, and gives a very crysp highs with no irritating peaks. The mid and bass are also well balanced. This is definitely one of the best universal IEM in my collection! I can't believe that you sell it at such low price ! Anyway, it's incredible !

      Nice

      Pros: very nice sound. clear high freqs, detailed. subdued bass, but still clear and detailed.
      Cons: A little bit heavy, so have to carefully choose ear tips for good fit (I have to make custom ear tips). No so good noise isolation. So with weight and isolation it s perfect for indoor usage but in crowd noisy places it's not so good.

      good

      I think that it is good to make it.
      I think the sound quality is beautiful.
      The faceplate on the right side is loose, but I am troubled because there is no tool to tighten it.

      How different between ACH CERAMIC UNIVERSAL IN-EAR MONITOR and KINGFISHER CERAMIC GAMING UNIVERSAL IN-EAR MONITOR except cable?

      Null Audio

      Hi Tak,

      Their tunning is also slightly different as Kingfisher is more oriented towards gaming sound setting.

      Hi there!

      Would the ACH ceramic IEMs be hard to drive? Can I get by by just using an iphone?

      Thanks!

      Hi.
      Will the earphone price be raised after the end of pre-orders and the start of mass production?
      Will interchangeable faceplates be available as an option? Or sold separately only?
      Thank!
