I received the 2015 Easy UE Custom IEM today. They sounded very good right out of the box. This is the link to the product details page on Aliexpress,

The product descriptions on that page were a little confusing. I think the earphones I got only have single dynamic driver in each shell. But none the less the sound is pretty impressive. I did a quick side-by-side compare to Z03A (also bought from Easy) and I like the sound of UE better (mids, highs, and soundstage).
As the webpage said, these UEs are hand-made and it took more than a week before they can ship from the factory. But the long wait is really worth it. The UEs also look pretty handsome. I switched to a pair of UE900 cables. I don't think I can hear the sound difference between cables but the UE900 cables are more comfortable. But they cost $46, a little more than the cost of UEs. So now I have a pair of $90 earphones that really rock.
The 2015 Easy UE Custom turned out to be an excellent earphones when paired with Comply foam tips. I have been enjoying them for the past two days and have not touched my IE80 and SE535.
I purchased these UE Custom based on Twin's review,
