I use the Comply 500 large on all three of my iems.  Gives me the best long-term seal.  I find that silicon weakens after a few days of walking, and sometimes gives me too much of a seal for comfort's sake.  I get 3+ months with a set of Complys before they begin to pull apart (I listen while I walk two miles quickly, so sweat enters into the equation).
 
The blues that come with the Altone refused to stay on (as many others have noted).  The tips that came installed were ok, but I settled on the Complys after a short test drive.

Ack! Talk of defective Altones is making me question mine.  I think they're ok, but how will I really know...

A really anemic bass would be a true sign that it's defective. Like it was described before in one of the post by H20, as the bass sounding like an AM radio.

Sounded anemic from my iPhone. Definitely does not sound anemic from my DX90!

Seems like you have a good pair of Altone's. Source plays a big part in bass quantity.

The included blue foam tips have probably given the best bass response so far, but I found they also make the sound more closed up, which I did not like. Originally preferred the sound from my Xperia Z Ultra with Viper4Android installed vs my ZX1, but now that I've found well fitting tips I'll give the ZX1 another shot. ZX1 seems to have the most synergy with the XBA-H3 more than anything though (probably not surprising, Sony pairing well with Sony).

Seems like a warmer source would be ideal for the Altone's. My X3's have good synergy with them. Also, Sony Hybrid tips seem to bring the bass out a little more as well as taming the the highs a bit.

kahaluu: Good idea! I'll give my X3 a try tomorrow. Have you tried adjusting bass or treble?

 

[kahaluu]

No, I haven't adjusted any settings.

H20 posted that they found the problem, a wire blocking airflow, so the fix is easy in terms of production methods.  A simple return (minus packaging, just the iems in a package) is all that is required.  
And I'm finding that as I get a bit more burn-in my sound is changing- more bass.  

Ya burn in improves the bass for sure.

I was sad to send them out, I was really starting to enjoy the sound on mine. The clarity and detail on them are unmatched. Sad, I only have like 50 other pair of iems to listen to in the meanwhile (muahahaha)

I have a new pair coming in next week too, so I'll wait for the new pair before I say much more about them.

question - the dynamic driver is mainly driving the bass? 
 
I feel the bass is there but seems to be a bit lacking. surprised the TDK BA200 has more and better quality of bass. maybe need more burn in time. 
 
on the other hand... 
 
Altone200 vs the TDK BA200: Altone200 has better clarity, better treble extension (a major downside of the BA200) but mids are thinner and a tad more recessed. BA200 is more intimate, warmer and more neutral with thicker mids. both have good separation and detail but because of the clarity on the Altone, it feels more so. soundstage is bigger on the BA200.

^ :/..... I don't hear anything of that sort , but mine are burned in for 54hrs

 

[kahaluu]

Burn in definitely helps. I've notice there is more bass on my unit with burn in and highs have tamed down a bit.
