The 10-driver in-ear monitors are the results of long time research and nonstop efforts for the best, and have carried on the same innovative spirits demonstrated in all products by Heir Audio. Heir 10.A are more than an upgrade from Heir 8.A in that the significant improvements of sound quality and music expression can only be described as a new beginning of the top monitors in their own category.

Brilliantly distinctive, the 10-BA driver monitors with four way designs are carefully engineered for better sound separation and layering. The Heir Audio's unique MSPM (Mathematic Sound Processing Model) simulates millions of sound combinations so that those 10 drivers can produce, at the same time, the most accurate yet magic representation of music with little trace of artificial maneuver often seen in others.
Bold, warm, neutral, rich, balanced, detailed large sound stage, tight bass, full mids and steady trebles are frequently quoted to depict the remarkable sound signature of Heir 10.A. More importantly, it can perform all kinds of music genres whatever you prefer. With 10.A, you can get what you want.

Indeed, Heir 10.A: the new King has arrived.

Happy with my first CIEM
I'm not really a pro on this and not as familiar with the different terminologies-- I'll try my best, but please excuse me if I use them wrong.

Compared to my Shure SE530 (the IEM I have been using), it definitely seem to have more definition. Listening to John Mayer's Wildfire, I think there's also more depth and breath (I could sense more sound layering if that makes sense)? It's definitely a step up. Additionally, it's way more comfortable. I am still getting used to it though.

Compared to my Beyerdynamic T1 (which I use more at home), the bass is bit more pronounced? Not sure if that's what people call "dark"... with some songs, I think it might be because I just got it and haven't had much burn hours. In fact, from the first song to now (as I am typing this), it already sounds better... Initially, the bass was somewhat overwhelming the higher notes... Now, it doesn't seem so... or at least not as much. One area where the Heir seems to sound better is vocals. For example, in Ed Sheeran's "I See Fire," the vocals sounds a bit more solid. Maybe it helps the Heir has a stronger bass?

I don't know... I might say subjectively, I like my T1 better overall? The different isn't huge though. It's also not a fair comparison I suppose. The T1 is open type full sized headphones and not really portable compared to Heir. Where the T1 really shines compared to Heir is playing the Magnificent Seven by Erich Kunzel/Cincinnati Pops and All I Ask of You (Phantom of the Opera).

If this helps to put things into perspective, I listened to a few FLAC songs by John Mayer, Ed Sheeran, Joshua Radin, and Linkin Park. Also a few DSD such as Magnificent Seven and the Phantom. I tried the thing connected straight to a TEAC UD501, and using a Schiit Valhalla 2 (tube) on low impendence. Total playing time is probably only an hour or two... so again, haven't really had time to do proper burn-in.
