634EARS Sarn II / Nigaki Wood

Yeah, the stock cable is a very basic one. Usable, but basic. The tips makes all the difference though since they're wide bore shallow fit.

He's definitely a character with passion, and such a generous person as well. I ordered a pair too, should arrive next week. BTW, how'd the treble turn out? Is it too much like you imagined?

Technically, in regards to transparency and detail retrieval the 8ite comes short compared to the EX1000, but that's Sony"s fault for being too good at what it does. One thing though that surpirsed me though with the 8ite is the soundstage. Its nearly as wide as the Sony's but with much more...

I don't know about the new entry models, but i remember him telling me he can do pentaconn ears and two pin as options on my model. The model i went for had the most mellow tuning, so i can't speak for the rest of the lineup. They're all derived from the same Fostex driver if I'm not wrong, so...

It's definitely an interesting brand, and I own one of their products the 8ite-t.This is my personal pair with a custom design. The owner, Musashi-san used to do custom re shelling for another Japanese iem company before leaving to do his own thing. The brand gained popularity after placing...

The native music app is bit perfect. The streaming apps are resampled to 48khz I believe. The Hi Res Streaming option upsamples that to 192khz.

Without any authorized reseller in EU or North America, getting a custom version is next to impossible. I've contacted aiuto(acoustune parent company) before, and they said service through their website is open to japanese residents only.

Pentaconn NIPPON DCIS Pure Silver Cable Pentaconn Ears - 2.5mm $200 USD Wagnus Cable "Moonless" Silver Plated OFC Pentaconn Ears - 2.5mm $150 USD Shipping and PayPal fees included. Proof of purchase can be provided for warranty.

From what I understand, the 1697ti should be identical to the 1695ti. The gold version was a test platform for the pentaconn ear connector and the myrinx composite driver, hence the limited run & availability. It was re-released in silver to fit in better with the rest of the lineup. And you're...

Acoustune released new in house cables, on sale Feb 26th https://www.aiuto-jp.co.jp/information/entry_1157.php

I absolutely agree. The way they present treble detail without sounding thin, mixed with the natural DD timbre is what makes them shine and even addicting at times. But I believe that some adjustments were made with the 77 series in which they added some gain around 8 khz & 10khz, making the...

For a clean studio like, mid foward, precise sound, go for the 1677. Timbre, and seperation is top notch. More sub-bass focused of the bunch. The upper treble might be a bit much as though, even on a warm sounding source. The 1670 might fare a bit better here from the graphs I've seen. This...

The tuning is too different for an apples to apples comparison. Both 1677 and 1657 have their own distinct characteristics which compliments specific types of music very well and while requiring less effort when source matching. The 1697 is the opposite with it's more balanced and subdued tuning...

3D Given the ss moniker, it makes sense that it's tuned like the 1677. Maybe they'll release a cu version with a bassier tuning.

I think given the impressions from the Youtuber, the 1300 is a more tonally balanced and sweeter sounding iem, a less bright version of the 1677 if you will. But again, he explained that because it's an entry level product with a 3rd gen myrinx driver, it can't compete with the more expensive...

Without knowing your preference, it's hard to give a recommendation and it's always best to audition a product before purchasing it. The 1677SS is very energetic and mid forward, so source matching is necessary to prevent listening fatigue. The 1697TI has a totally different presentation, so...

Impression video for the 1300 in Cantonese for those who understands. I own all the 16xx series, and I'll leave this link here from a Japanese blogger who's impressions exactly matches mine and goes into detail about all three...
