Arrgh Stop with the temptation 

Still torn on the 3.ai vs the 4.ai. 

 

How well could I EQ some bass into the 4.ai, If I decided to? :o

 

^^ that question will probably determine whether I purchase the 4.ai or not :P 

The 4.A(i) has very nice bass and takes very well to bass boosts or EQ'ing. Although with the Black Friday deal The Wizard just posted, I'd go all the way with 4.A customs. Even with the best of tips, the comfort you get with customs is just on another level.

Hello,

 

I already have the 4ai,

 

Speaking about sound quality, does the 4A give something better/more vs the 4 ai?

I *think* Sinocelt is the guy who owns the 4.A and has tried the 4.Ai - he should be able to comment on any sonic differences, I can only tell you that the comfort on customs is way beyond anything you can get with universals. The downside is that you'll have to factor in the costs of shipping and impressions. You'll also be giving up the ability to let others try your headphones.

I'd say that the custom shell of the 4.A does a few things: (1) it gives you more even isolation throughout, so you can hear bass and treble extension better, (2) the "insertion depth" is set, so certain resonances brought about by the ear canal are minimized, improving overall transparency and imaging, (3) acrylic is a single, fairly acoustically neutral material, so furthermore, the FR and phase response won't be altered from what it was originally intended to be by silicone tips, (4) superior comfort for long term use.

Hi, can you recommend some DAPs or DAP>LOD>AMP to pair with the 4.As?

 

 

I wish to bass boost or EQ like what you have mentioned. 

 

Like Tom, I own a 4.A and have tried the 4.Ai.

As long as you watch out for the output impedance, anything goes. I've used them with just about anything from the Clip+ to my Ibasso DX100.

Hmm what do I do now then......order some custom 4.A and sell my 4.Ai or stick with the 4.Ai.......decisions, decisions.

I wonder what the lead time on these will be at that sort of price.....don't fancy having to wait 3 or 4 months..

 

It was definitely a surprise that the two faceplates didn't really match like other sets that have been posted in this thread, but I quite like it! It makes me feel special, almost as if I special-ordered two different types of wood. If nothing else, it reminds me which piece goes into my right ear and which piece goes into my left!

 

My first picture doesn't do the left earpiece justice. It's nowhere near that grainy (stupid camera/lighting). The second picture is much more accurate as to what it looks like in person.

Damn you Heir! That 40% discount is going to make it difficult to sell my 4.Ai
