I'd say save up for the DZ9, ONLY because that's what I have been using for a year +. And GOD DAMN they surprise me every time I use them. They sound unreal. The instrument separation, and wonderful mids and balanced highs/lows. Voices sound absurdly nice.

Any drawbacks to using a small tip on the one side and a extra small tip on the other? Will sound/isolation be impacted? My ear canals seem to be different sizes.

  I agree. The only thing I'd complain about is the tiny skip it does between songs. Gapless playback isn't too great.

Just a small psa for anyone that orders these through HCK: my DZ9's sounded awful when they first arrived. Congested and terrible. BUT!! It wasn't the iem's fault. It was the supplied CABLE.  Immediately after changing the cable to another one I had...WOW, the real sound came through.   So I...

Just a small psa for anyone that orders the DZ9/DZ7 through HCK: my DZ9's sounded awful when they first arrived. Congested and terrible. BUT!! It wasn't the iem's fault. It was the supplied CABLE.  Immediately after changing the cable to another one I had...WOW, the real sound came through.  ...

  So glad to have joined! I'd happily pay $1000+ for these iems. The sound is that good.     They're pretty much my ideal design. So glad I splurged on them. Usually the glittery "stars" design has a smoked black body, but I asked the seller if they could make it completely clear instead...

Got my DZ9's today!       

  To give perspective, that's pretty much how the UE900s sound signature is, period. No source fixed that for me (X5ii, Macbook Pro, X3ii, iPod Classic, iPhone 6s, iBasso DX80). All sources were the same since that sound is just a characteristic of the UE900s you can't change without EQ.

  So nice! Might be my next iem after the DZ9 also. What do you mean by tighter bass? Damn, can't wait for my DZ9's to arrive.

I ordered both on amazon and they sounded exactly the same. Did a blind test and couldn't point to any differences using a UE900s. Returned the X5 kept the X3.

  I agree! The PT15 is phenomenal! I also absolutely do not agree with the highs being too much. I think they're a bit rolled off. The high mids though are sharp without foams, but the donut foam covers eliminate them. Coming from a UE900s, the bass from the PT15 is more than sufficient. I can...

For what it's worth, I've never had an issue with HCK. Not saying they haven't screwed anyone over, just that I've never had an issue. If anything, Jim's gone above and beyond whenever I've asked him questions. Lot's of patience. 

There's a new 3BA iem from HCK's store: 2016 New CTZ 3BA    https://www.aliexpress.com/store/product/2016-New-CTZ-3BA-In-Ear-Earphone-3BA-Drive-Unit-DIY-HIFI-Monitoring-Earphone-With-MMCX/1825606_32775729468.html       These look pretty incredible imo. I love how they're styled.

  They just shipped two days ago! Although I don't have DHL since the price wasn't $480+. :'(   I'll hopefully get them in no more than two weeks!  

  it's a VEEEEERY faint noise.

To those with PT15's, does the sub-bass audio from the "Quality" section from this site http://www.audiocheck.net/soundtests_headphones.php make the earbuds make a slight rattling noise in the lowest subbass? Mine do, but I have not heard it in real use so I'm not worried.   

You will not be disappointed. It is phenomenal.

  Ah so that was the fault of the cable?

  That's super unfortunate. Out of all the sellers, NiceHCK seemed like he mastered the english language the best. I always message through Aliexpress's message system since the chain of messages is literally a scroll away. You can't start a dispute and let Aliexpress foot in the bill? $36 is...

  Awesome! So it's a good, balanced sound I hope, with not too much focus in one area (maybe just a bit more mid focused if I understand you correctly.)

  Would you say that the highs are lacking in any way since it's so mid-focused?

Ordered the DZ9! Got the Stars version but asked for the base to be clear (instead of the smoky black). Now the wait begins. Hopefully these puppies are end game.   I also got more info on the DZ8: DZ8，8BA！ 4way，2 super high，2high，2middle，2 low   Compared to the DZ9:   DZ9， 1+8 is 4...
