Pros: They have the sound that WoW me letting me enjoy Music without me becoming analytical and consequently up not enjoying music
Cons: I don't have any compalins about the 4.A
Well this is my first (second I have the 8.A and I wrote this same review for the 8.A since I compared them both) review ever and I am doing it because it would be unfair of my part not to talk about this two excellent pieces of audio after THE EXCELLENT customer service I received from John, and I know some of you might get mad about this review since I am not going to focus just on their Sound Quality, why? because It's been said enough about the sound signature of these two iem’s that you pretty much have an idea about their sound but the main reason being that since music gear became my hobby I did not enjoy music that much because I was always looking for the perfect sound in headphones or earphones and I came to realized that there is not a perfect headphone or earphone since every time I got a new pair of iem’s or headphones I was like “the mids of this iem does not compare to the mids of this other iem”, etc etc etc so I always ended up not enjoying the music but analyzing it.
So I just wanted a good set of iem’s that would WoW me and that I could take with me every place I went, so I decided to get a flagship custom iem and to sold my Seinnheiser HD800 and Ultrasone Edition 8, I am someone who likes to take long walks and to think about life and I could not take with me the HD 800 besides I was tired of dealing with desktop amps and the later because I was afraid of scratching them and I did not like to draw too much attention to myself especially here in Miami , and having had the Shure 535 I knew that by getting some custom flagship model things could only get better.
So I started investigating about them and sending e-mails different ciem companies, asking them questions about their products, and that’s how I got to meet John , he responded every e-mail within hours and sometimes within minutes I had sent them; as a matter of fact, sometimes I was the one who could not reply to him, and this was important to me because of the investment I was going to make, the other companies I e-mailed replied to me a week after or a couple of days later, I won't say who they are since I don’t know how busy they were also because I work in a custom glass shop and I know it's not easy to keep up with the customers, but the help I got from John was enough for me to go with Heir Audio that I decided to get the 4.A and the 8.A, and it was the best decision I made in 2012 music wise.
I have them since March this year and I am writing this review now because this was my last year of college and it was a busy one I barely could keep up with going to school and having two jobs at the same time, I got to confess that the 4.A are my favorites ones because to my ears the bass, the mids and the highs are in sync with each other and they make me forget about everything else I just enjoy that moment when I’m listening to my favorite tracks, and every time I listen to the 8.A I am thinking "damn I wonder how this song would sound with the 4.A", and there you go I become analytical again lol, I listen to my 8.A when I listen to pop, techno or Latin music because of the many music instruments used with those genres but because I am a rocker and most of the bands I listen use the basic instruments you know guitar, bass, and drums and obviously vocals the 4.A gets most of my time, TO MY EARS they sound neutral and that’s MY SOUND.
The best analogy to compare these two ciems would be like loving your wife(8.A) and having an affair with that pretty lady(4.A) you still love your wife but you just can’t stop thinking about pretty the lady and you don’t know what to do other than being slick and keep them both !!!
In conclusion if you get any of these to iem's you won't regret it! I will upload pics of them in a few days!!!
I paid for the 8.A $1500 (checkboard inlay), and for the 4.A $500, I am not including shipping and handing and customs fees
I gave them 5 stars in value since many people do not appreciate what it takes to make something custom, anything you name it, and I know what I am talking about, as I said before I work in a custom glass shop and I know how hard it's to make something custom from scratch! and the checkered board I got for my 8.A is TOP QUALITY AND CRAFTSMANSHIP!!!!
