I think any IEM or CIEM reduces the level of ambient noise but does not *cancel it.
I don't get 100% noise cancellation by any measure. But the seal on my 4As feel "right", you know like the audiologist got the impressions done correctly and the staff at Heir Audio got the acrylic mold correct too.
Perhaps others with more experience could explain how they *knew when they had a *bad seal?
Well, customs get good isolation, but they're not perfect. I hear traffic if it's close to me, and louder sounds will definitely report. A bad seal usually manifests itself with "air" --- like hearing the air come out of a leaky tire or ball. That type of sound is what you'll mostly hear if you have a bad seal, because it mostly works the same way --- air is leaking through a small aperture(s).
Hey guys,
I was hoping if someone from Heir Audio can comment on the spalted tamarind wood. Here is a photo of one customer's spalted tamarind.
Before I purchased my 4A, I looked up at what spalted tamarind could look like and I came across something like this.

Both look substantially different. My question to Heir Audio representatives is that are your spalted tamarind wood substantially different or will most of your customers get a wood like the one in the first link? I don't really like how the wood looks like in the first link so that's why I am asking.
Please advise....
We all know that we don't just hear from our ear canals? The entire ear and the the bones in our skulls help us hear stuff. So a 100% quietness when no music playing may be a bit unrealistic.
But as a cat person, I absolutely love your comment about your wife's dog :) I really can't take dog barking.

Generally if you have a really good seal and with music playing it should really help to drown out most noise if not all. I'd say in a reasonable settings it would drown out all noise. With my Custom TF10s even with no music playing it really helped to get rid of most noise pollution although I could still hear things but nothing like not having them in. Put music on and I couldn't hear a thing. Maybe it could also deal with how our ear canals are shaped. Maybe some get more isolation than others depending on this.

When music playing I don't hear a thing from what my really loud friend says right in front of me. I think a better way of judging the seal is bass. If the bass is not there to begin with, then it is very likely that the person does not have a good seal. All I was trying to say was to give people some peace of mind when they can hear stuff when there's no music playing.
If you want that type of isolation you'll have to opt for Silicone IEMS like Sensaphonic or Spiral Ears.

Well bass is a very good indication as well. Honestly that is universal on all IEMs IMO unless the IEM has no bass ;)... Actually I found the Custom TF10s to have way too much bass compared to it in universal form. So obviously the fit was really good, just painful :P.
I've had two sets of custom tips for Westone IEMs. The first fit perfectly and cut out as much, if not more, background noise as Comply tips. Sound from around me seemed evenly attenuated. The second set had excellent bass, but the treble was harsh. I could also hear sharp high pitched swishing environmental sounds when I had no audio playing. So, a small spectrum of high pitched sound was leaking in.
I'm waiting for mine too :( was hoping to go snowboarding in them but guess it'll only come after im done boarding. Some one knock me out till they arrive :(
Here are some of my personal test tracks for bass response:
Thom Rotella Band -- "Friends" (the slap-bass stuff comes in at the middle of the track)
AYA Are You Authentic -- Authentic Audio Check tracks 3 and 4: http://www.elusivedisc.com/ARE-YOU-AUTHENTIC-AYA-AUTHENTIC-AUDIO-CHECK-SACD/productinfo/SFSA9011/
Sarah McLachlan -- "I Love You" (when I hear this track on a hi-fi system with a good subwoofer, I swear the floor moves!)
Joshua Kadison -- "Invisible Man" (I think there is a cello bass playing as part of the backing music)
