Or maybe they will strike gold (pun intended) again with the new model.

I am placing my bet on the Trinity Atlas Delta.

  Will give that a try.
But if that doesn't solve the problem? They are only one year old.
Any warranty procedure with LZ?
How to contact them?

I think you can contact the retailer.
 
When I buy DIY IEMs, I don't expect there is warranty.
Though if you buy the IEM directly from LZ through Taobao, he does offer warranty. HOWEVER, it is kind of impossible to ship the IEM back to China because of the custom...

have anyone try it?I have lz a2s and lz a3s but I think lz a2s not balance bass too boomy and lz a3s more balance and have more micro detail but bass is not deep.but I love sweet vocal in lz a2s if a2pro more balance and have good bass it is very good.

Well if the A2 pro brings back the old A2 sound that would be a winner for sure.  I have never really seen a review for the A2S or A3 that raved about the units the way people raved about the A2.
 
I think the A2 is a sweet spot IEM.  Under $100 yet holds its own with more expensive units.

 

[originalsnuffy]

Has anybody reviewed the LZ-A4 in comparison with its grandpappy; the LZ-A2 ?
 
I pulled the A2 unit out today to compare the bass response with my FLC8S.   The FLC8S wins in the mid range and treble; but I think the A2 holds its own in the low range.

 

[twiddlingthumbs]

Has anybody tried the LZ-A2 pro? Does it really have the same sound as the original LZ-A2 as they claim?

TwinACStacks has a review of the A2 Pro with a comparison to the A4 at least: http://www.head-fi.org/products/lz-a2-pro
