Picked it up from the post office maybe an hour ago; it sounds great. One of the "fullest" sounding IEM I've ever heard.
First time owning/listening to a hybrid IEM and I certainly can see the appeal of it.
At the moment I only have 4.Ai with me, but speaking from my memory 1Plus2 is another IEM that's very hard to describe; just like how many had hard time describing sound signature of TG! 334.
Before anyone gets misconception that 1Plus2 has overwhelming bass like IEMs such as IE80, it certainly doesn't. It's not a basshead IEM by any means. For now, 1Plus2 is neutral, yes neutral. I think some people assumed that 1Plus2 is warm due to the highs and lows having little punch to it. It's not muddy either, very crisp and nice. It offers something none of my BA/dynamic IEM does. EX1000 sounds pretty freaking good, it has wide soundstage, but I have to focus a bit if I really want to hear all details; even more so with IE80. We all know that BA IEMs are very good with microdetails, but if it's not airy then it's muddy like PFE232.
As earlier, I mentioned it sounding "full", I am not sure how I would describe it. It's not "airy" like 4.Ai, but it's not bloated and loose like IE80. It's like a chimera. Detail wise it's BA. Punchiness wise it's dynamics; but very crispy and nice. Best of both worlds.
Vocals are very mid centric, while everything else is bit more forward. Very fun IEM, certainly isn't a studio monitor replacement (you'd want speakers that are as flat as possible) due to the nature of EQing process when you record and master tracks. But for everyday listening? I would certainly recommend it if you are seeking BA with more "natural feel" or dynamics with more "micro detail".
For those who are curious about fitting, it's mixture of 334 and 4.Ai. Yes, that's a good thing.
