If don't know about Symphonium Audio or Subtonic by the time of this writing, then I don't blame you - until I got the tour unit I don't either. Though by chance if you know @toranku, then you might know a bit about Subtonic, though that's as far as I can say. The Symphonium Helios is a collaboration IEM between Subtonic and Symphonium. If anything, this work also marks the first appearance of Subtonic in the market. Incidentally, with its pricing of ~1000$, both brands are showing their confidence in this collaboration by challenging the renowned...

This was unexpected coming from them. Though now that I think about it, this should have happened sooner or later. Etymotic, a brand whose age is nearly double the time that I spent on this earth. Though still relevant in the scene thanks to their iconic ER4 series as well as good audio quality. Personally, I own an ER4S in my collection and I know a handful of users (from the industry and enthusiastic scene alike) using Etymotic IEMs daily. Through the EVO release, it's quite clear how Etymotic is trying to achieve. A pseudo-custom IEM with...

With how Moondrop advertises their product, I think a lot of Audio enthusiasts who happen to be Anime fans will know them.

It seems like now Moondrop decided to revisit their old Aria model and gave them an update, though from the look of it the aria is more of an iteration of...

Despite being quite popular in Japan, Acoustune doesn't have that much reputation in the Vietnamese community. That doesn't come as a surprise though, since I understand that there are more risks for local storefront introducing this brand into the market, hence demoing sources are sacred. Though, since the beginning of this year, I have moved to Japan for personal study so I decided to try out the brand just to see how it goes. Hence, I bought the Acoustune HS1300SS since it's a recent release (at the time of this writing) and also it's affordable...

About me: I am a student who loves to talk and write about everything I made and found. Music/Audio happens to be one of them as I listen to music daily and play some Piano/Guitar along the way. My music preference is Rock, J-pop and especially Instrumental, I do listen to other genre of music if I happen to enjoy the song provided. The review is from my website: https://banbeu.com/tin-hifi-t4-review/ with some editing to fit the time I am writing. Introduction: Tin Hifi, despite my dissatisfaction with the P1, they still seem generating new...
