Imagine yourself sipping warm tea while the sound of flowing fountain inside your ears.
That's Flat-4-Sui, an IEM of art.
First and foremost, this IEM has a V-Shaped FR. The mids (especially vocals) are laid back.
The story thus far:
I've been listening on my Shure SE535LTD for quite some time. I kept on thinking that BA-based drivers lack a certain thing. A quality that often presents in a great dynamic-driver IEM. It's not that SE535LTD lacks anything tremendously in terms of sound quality, just that I felt I can't grab the flow of music.
Until I met Flat-4-Sui.
It was a dilemma to choose between Sony EX1000 and Flat-4-Sui ($500 and $700 respectively). It's my intention that I do not venture into Custom IEM yet, and I would like to add an excellent dynamic-driver IEM into my treasure box. And I expelled IE800 from that list as from the impression of the Head-Fi IE800 thread, IE800 has the same house signature of the IE8/IE80 series, which the bass is too strong for my liking. I didn't have the chance to try out JVC HA-FX700, so it's still a mystery to me (will try it some time). When I was about to go for the discontinued EX1k, it was out of stock. That left me with Flat-4-Sui.
The day I received the IEM, I gulped. I was really disappointed with the packaging. There is literally close to zero accessory. Come on Ocharaku, just a pair of Comply T200? No earphone case, no other tips, not even a simple bag? I guess they expect the users to be so carefree that they will store the IEM back into the round aluminium can after use. The housing itself is plastic, and the cable to me is poor. It looks like it can break anytime. My first thought was: I was conned into buying this product!
I plugged the IEM into my ears. Well, my first impression was, certainly this thing doesn't worth that much! My overall feeling was that the sound signature is V-shaped, and reverberation. can be heard on a feel tracks. On some tracks, the sibilance is more apparent and on some, the treble tends to be sharp. Bass is present, extended and controlled. But how could I justify it for skipping EX1k?
Ocharaku is founded by the ex sound engineer in Sony, and well, if you mind going to the website, ocharaku.jp, you'll see information on tea (apparently this dude is into tea and art). http://ocharaku.jp/sound/ is where you approach the product information, and most importantly the engineering concepts behind the IEM's unique design.
Well, the IEM has underwent around 100 hours of burn-in. And well, all I can say is, THAT'S MORE LIKE IT.
Here're some pictures I took:
The Left/Right earpiece is easy to spot by identifying the little hole on the housing. The little hole means it's facing back.
