I received my order today. The packaging itself is just the generic pelican case containing the IEMs, cables, and multiple sets of tips. No documentation included.
Off the bat, they sound much better than the Toneking T88K. The T88K sounded flat to me, while these are much more to my liking.
I wanted to compare these with my recently received BGVP DMG (which I have been using for 3 weeks as my daily commuter). For both, I used Comply Isolation T-200 tips with waxguard. I wanted to make sure I was using the same tips for both as tips can make a big difference. After listening to the same three songs on each, I would give the edge to the Crescent.
The DMG are excellent (using gold tips), and are definitely better than the T88K, but to my ears and my type of music, it doesn't match the Crescent. At the same time, the Crescents are 3x the price of the DMG, so is it 3x better than the DMG? Answer to that is absolutely not, which is a testament to how great the DMG are. I don't have the DM6, so can't compare the Crescents to that set.
One thing, the nozzles on the Crescents are huge, the Comply Isolation T-200 tips I have fit the DMG, the T88K, and UE900s without any issues, but it took a great deal of coaxing to get them on!
The shells of the T88K are bigger and heavier than the Crescent, T88K to my ears felt like CIEMs going in, but were more difficult pulling them out. The T88K I also has a hole in the shell for a vent, while the Crescent don't.
Finally, regarding the cable on the Cresecent, it doesn't have an adjustment piece to tighten up the cables closer to your head, which I was surprised as I like a tighter, neater fit of my cables.
Since I only got these about an hour ago, I'll use these as my daily commuters and see how they hold up as so far, every IEM that I have with Knowles drivers have failed on me and either needed to be replaced or returned for refund, which included the T88K that failed in it's third week of usage.
