Still.... waiting for the group buy.

Still.... waiting for the group buy.

Neutral, analytical, warm....I think those are the key words you wanted. What you mean slight v-shape? They are extremely fun in the sense that they make music sound great and i love walking around dancing to the music with them on. That's fun to me![]()
There was absolutely NOTHING v-shaped about the AS-2 prototype I heard. If anything, it was slightly mid forward. It was definitely on the neutral, slightly warm side of things.
[size=18pt]Sound[/size]
[size=13.5pt]The overall sound signature of the AS-2's is flat (1). Each of the three normal divisions of the frequencies are equally balanced with each other and this makes for a fun experience (2). The important thing about the AS-2's is that no matter how much I have tried boosting any single part of the highs, mids, or bass the overall sound from the rest of them is still superb and unaffected.Each section is well contained and little to no leakage between them means if you like it more bass heavy, go right ahead, you will still hear everything crystal clear. A song by Bassnectar called "Ping Pong" samples a ping pong ball bouncing around. The 3D imaging is amazing on the AS-2's, but if you turn up the bass levels you will still hear the clearness of the ball bouncing around like it was a leaky faucet dripping a drop of water in an otherwise silent room(3).[/size]
[size=13.5pt]Treble[/size]
[size=13.5pt]This is the area in which those two tweeters come into play. The highs are interesting on the AS-2's. It's this part of the AS-2's that I guess one would think the tweeters are standalone and separate from the 15mm dynamic driver in them, but to my understanding this is not the case.The balanced armatures in the AS-2 seem to compliment the dynamic driver to ensure that you are not just able to hear the highs, but also hear them well and enjoy them equally(4). Listening to music with really high notes hit by a vocalist is spine chilling (5).It's a great feeling to have something that hits hard as needed in the bass and still delivers like this in the treble space(6).[/size]
[size=13.5pt]Midrange[/size]
[size=13.5pt]The midrange of the AS-2's are lush. They are warm and inviting to you as a listener (7).I find the midrange to be perfectly tuned for the other frequencies to complement them. Similar to the treble,the midrange is quite airymaking the two seamlessly co-exist in a unity of spaciousness and yet similar sound qualities.The midrange is airy and textured. It really makes you feel like you are there as you hear the pluck of the guitar in front of you (8).the tweeters used for treble levels mean the midrange is not overpowering the trebles at all(9).The midrange feels like so much of the rest of the AS-2's, which is a product that you can tell took some hard work and care to make and perfect.[/size]
[size=13.5pt]Lows/Bass[/size]
[size=13.5pt]It's something I have been talking throughout lots of sections of the review and rightfully so. It's amazing how the 15mm driver inside this In-Ear Monitor performs so well with all the frequencies and realize that it also handles the bass at the very same time.The bass iscrispand clean (10).In the past with my headphones that I have had that were considered Basshead headphones, with great bass, I never had anything like these.On tracks I previously thought were mastered poorly because it's bass did not produce much rumble or have much depth to it. With the AS-2's, the bass still does not lack it's clarity and texture when testing with those tracks (11). The bass goes well below my previous headphones, the Denon AH-D2000's that have quite a history of Basshead territory in the audio hobbyist community (12).I highly recommend anyone worried about finding something that'll give them that bass craving they have but fear losing the rest of the frequencies or even just think it'll be too heavy.It's a bit hard to get a handle of, but I can't think of any other way than to say, the AS-2's will perform as close to how the master engineer for the song intended it to sound. If the song is meant to have light bass, that's how the AS-2's play it. Yet at the same time, if the next song calls for lots and lots of bass, it'll deliver that as well, nice and clean, without any change of settings. In actuality, that's how every headphone or In Ear Monitor should be, but I have never found one that does on such a consistent basis until the AS-2's came along.[/size]
This is what people said about the ASG-1 1.2 revision when it was first released... That's the problem with that. The words and these descriptions just don't add up. The ASG-1 (1.2 rev) was called mid-forward as well, which it is far from. It's nothing against you guys. I just don't know what to trust any longer. I'll wait until they are released to see what they are.
For example, I'm trying to figure out what the different parts of the spectrum are like in Kenman's original review, and I've highlighted the information I can actually use to construct something (and what they mean to me). Areas in read are what I attempt to interpret (numbered areas are the ones I will explain interpretation(s) of). Cross outs are what don't matter in terms of sound signature.
The areas marked with red all can be interpreted. The rest either is out of place, or doesn't make sense. Or it adds nothing to the conversation by giving a vague feeling of quality to the monitor. This is how I read every review. So lets get to comments (numbered):
- The signature of these headphones is flat. OK, there are many ways to define flat. Flat can be having a flat FR response which will have a mid-focused, sub-bass deprived sound to it with a dip in the 2k region that is perceived. Reading on, that isn't that phone. So I assume you mean a balanced or neutral sound (neutral is balanced, balanced is not neutral to me).
- You make a statement about normal devisions. There are no normal devisions. There are devisions, but none are universal. No reviewer has come up with a universal where these devisions occur. For example, I still consider 2k part midrange (higher-kids) while many consider this area the treble. This is why you have to be direct with your words and look to the glossary we use and learn those terms.
- It has a large sound stage. Thanks for that information. However, soundstage says little about the signature (analytical, neutral, balanced, v-shaped, etc.). Generally speaking, the more colored (un-neutral) an IEM is, the smaller the sound stage. There are exceptions though, this might be one of them. But I'm already in doubt about either the neutral sound or huge sound stage.
- Your first statements about the driver say absolutely nothing about the sound. Dynamics can be tuned to sound like BAs, and vice versa. The fact that you can hear highs says nothing to me as well. Every headphone has this property, even the treble-recessed ASG-1.
- You created a line to start the treble between 2k and 4k (somewhere in there is where you define treble starting). This is fine. It does give me the first bit of information, the headphones are sweet. That is, there is a bump around the 2-3 k region. This is something I'm happy to hear actually.
- Your statement of big treble and big bass immediately have me leaning towards a V-shape. The sentence itself is very confusing though (in my eyes). So I may have interpreted wrong. Reason why it's crossed out (it will not be used in my analysis of the signature).
- Midrange is lush means a bump prior to the 1k region for me. This is good information. Warmth generally means a bump in the same area (slightly before it actually) which is why lush is normally paired with warm, but not always. Warmth can also be created by a slow decay in the lower-end of the spectrum (how the HF2s and ASG-1 (I assume) do it).
- Airy actually ensues an area in the higher highs. This is well past the area of "splash" and most say is inaudible most of the time. It is thought to create an airy feeling, and for the most part, it does (all headphones I've heard that have this are airy). There obviously are other ways to create air, this is the most common. You also make a statement about textured. I myself would place this in the bass region, but it can be attributed to the midrange. This shows an increase in the higher sub-bass.
- The fact that the treble doesn't intrude the midrange is good to know quality-wise, but helps me very little in trying to construct the FR curve you're hearing. Essentially all signature types can have it where the treble doesn't intrude. Same applies to bass intrusion. However, bass intrusion normally points to big bass, treble intrusion doesn't imply big treble.
- Clean bass implies that it isn't boomy or big. Perfectly fine, good information. However, lack to declare what part of the bass is clean does give less to the statement. I've never heard crisp bass, it usually deals with treble.
- Huston, we have rumble. That normally is due to a bump in the deepest sub-bass. It also gives the idea that the bass has good depth. Good description here.
Using all this information, I come up with the following curve I would perceive the headphones to have using EQ.
All descriptions are in the picture of why things are the way they are as well as the three parts that define a v-shape for me. I don't consider this a v-shape persay, but rather a balanced sound. Not flat, not neutral. Warm, but not analytical. This is the picture that I have in mind of the AS-2 (based on my interpretations of the review). It's not going to be the most accurate, there will be guesses. However, it contradicts what the OP says in terms of the review. Reason why I'm confused. What people are saying, and what their reviews say are not the same. Hence, I am confused.

Don't forget. That at different volumes the lower and higher frequencies are emphasized as well as you should account for a slight depression in each freq. graph you make as the human ear naturally perceives the midrange created by the headphone to be more forward than reality.
Mighty impressive. Thanks for doing this. Sorry my original review was not as helpful as I would have liked. I meant flat as in Neutral, they are very well balanced. If you have paid attention I did a comparison with the UE IERM's at a Head-Fi Meet and they had similar qualities enough it was hard to tell which ear had which IEM in besides the slight more present and controlled bass on the AS-2's. Volume matching them made the UE IERM's sound thin compared to the AS-2's.
Anyways, when I say neutral, I mean each frequency is perceived to be given equal emphasis. When I say it's controlled, I mean that each frequency sounds like it is well contained and if I boosted or lowered any one of the frequencies I have not noticed it drowning out or being drowned out by the rest of the music in the other frequencies. By Midrange, I am defining around 1kHz-6kHz, that should help you out a bit.
I tried to stay away from words like mid-forward as I have no idea if they really are or not. I don't know how to quantify the sound enough to say that. Maybe someone can explain it. The way I see it everyone hears slightly different so while I hope my review is helpful, it's ultimately up to each person to make a decision and hopefully more reviews will come out in the future and people will be able to make even better informed decisions. I was in a music store this week and was checking out the headphone rack and asked to A/B some of them and I got talking to the guy working at the store. Turns out he met Dale and heard the ASG-2's and when I said I owned a pair of the custom model he was stunned and also told me instantly he was very jealous. It was a great moment for me to have met someone that can understand what I have heard, even in a slightly different form (Generic model vs Custom model).
Off-topic, well not 100%: I feel that the words, neutral, flat, and natural have all been thrown around way too much lately and have really mislead a lot of people into what they are getting. The ASG-1 was read to be flat up to the end of the midrange (where the treble dropped off) while things like the Monster NCredible were called neutral (I haven't heard them, but I doubt they are) as well as the MEE A161p (they are close, but need more treble) all being called neutral (or flat). None of these claims are true. Natural is different to everyone. The GR07 has also been called (perfectly) neutral by everyone as well. However, when people describe it in extensive works, it doesn't read as if it is. Once again, it reads more like balanced. I have a feeling that the AS-2 sounds a lot like the GR07 signature-wise though. Which is a good thing really (they are well regarded around here). That means very musical, but also holds its own with a respectable amount of accuracy.
Good info & cool graphs.
I'll go ahead and reiterate this.. and I feel quite comfortable in saying that know a thing or two about headphones, frequency curves, and technicalities.. there is NOTHING v-shaped about the AS-2.![]()
I don't want to get carried away... But I would have to agree with the post that I will be linking to. Headphones like those created by Etymotic are not what I consider neutral. They are overanalytic. True neutrality should be something along the lines of transparent.

I really want to see a picture of other customization options and the Black Rhodium AS-2. Acquiesce to my demands oh Head-Fi Gods!
:3
On a side note: From my perception (I have not tried any IEMs from Etymotic), there seems to be a general consensus or at the least a large number of people who consider the Etymotics to be bass light, detailed/analytic, and slightly thin. I cannot say for a fact that these claims are based on truth, but if they are the truth then I would say that is not neutrality. To find perfect transparency is a noble feat, yet extremely difficult and quite possibly impossible.
