Very good sound. I am satisfied.

Fit feels great, W900 definitely is something special. Phenomenal sound!

Technically this is strong at all aspects but somehow all the musicality is still present, many other technically strong earphones seem to result in a clinical feel.
With the W900 you get a smoothness, even in all the complexity, the signature is so very well balanced across the whole spectrum.

As I’m sure you can tell I really am impressed with the W900 and it has the perfect balance between musicality and reference.

Sound stage is so very expansive and the signature coherence really gives a level of refinement, placing the W900 in amongst the top tier league of high end earphones.

The W900 a hybrid reference monitor with good layering, imaging and instrument separation. It is easy to pick up alot of details and instrument positions with this monitor.

The mids have enough body without being overly forward or aggressive, making vocals a pleasure to listen to.

The bass is another strong trait of the W900, the strong, impactful bass kicks in at the right time and moment with great control.

For years, I have been more accustomed to a warmer/fuller sound signature such as the fitears/westone monitors, but owning a W900 made me appreciate what a hybrid reference monitor can do; bringing out immense amount of details in an exciting manner.

To start off, i am not a advanced reviewer who can describe a piece of equipment in detail technical aspect. But i would like to share my experience of my W900. i was auditioning W500 back in Nov and really like the bass it was delivering. I then sent a msg to Kevin and realized that W900 will be launching and he was asking if i would like to hold on for a while. When i auditioned the W900 for the first time, i didnt find it as intriguing as W500. The bass didnt seem as impressive as the W500. In fact it sounded a little flat to my taste as i was looking for a V-shape sound signature. However, i noticed that the W900 was a very revealing piece of iem. I could suddenly hear a lot of details that i did not hear before. Essentially it was like upgrading from full HD to 4K. I therefore made the leap and ordered a pair. Now, I am getting hooked to W900 as i am rediscovering all the albums that i have with even more details that i have never heard before. As for the build, they were very well built with no bubbles or flaws. i have requested for custom artwork for my order and they look lovely when i got them. Although there was some fitting issues but it was resolved promptly and now i have perfect fit and sealage. Fantastic job to the guys at AAW.

I really like this iem, and I have high expectations (I own SE5 Ultimate, KSE1500, S-EM9, Prophile 8. etc.) and I was not disappointed.

It is airy and spacious, very detailed, and musical without being too colored. What is particlulary impressive, is that besides have 9BA + 1dynamic, they sound very coherent. The bass is very punchy but tight, controlled and detailed. Mids are clear and even, high are extended yet completely smooth and non peaky. Some could think the highs are not so sparkly but I like this sound, it is not fatiguing yet technical.

All in all, if you look for a great reference all rounder, you should consider these.
