🔶 Letshuoer S12

[PopinTeddy]

Don’t have a measuring rig, but imperceivable to my ears

[nymz]

All good

[senegalas]

How is the resolution? Does it pick up everything like timeless does?

[nymz]

To my ears, is more detailed, without being as harsh.

[senegalas]

Compared to timeless? What are other differences?

Shuoer S12 unboxing impresions Disclaimer: Special thanks to Joseph and @shuoer team to make sure I could get it ASAP. You guys rock. [IMG_20220106_232011] January 6th. First IEM of the year arrived. Let’s pause for a minute here. Around 2 weeks ago, I was speechless about Timeless resolving power for the price - 200 hundred bucks for this? Sure, sign me in. 1 week ago I did my favourites of the year list, Timeless climbed to the a runner-up on the Best IEM released in 2021 that I’ve trie…

In case people missed out on the early bird sales, @shuoer is running another promo! Go go go

[Aromato]

thanks for sharing, how much was early bird price?

[ttorbic]

It was 129.99 USD for just the S12

[thoohil]

Easy and decent sub bass treatment for the S12 with parametric eq.

EQ applied:
Low Shelf @40Hz
Gain 3dB
Q 1

Sound demo with disclaimer: As always in reality it sounds different, this only for rough comparison.

Low Shelf EQ - Sound Demo - Shuoer S12 vs. 7Hz Timeless (Kool Keith - Diesel Truckin')

[ttorbic]

Cool! Have you tried putting a tuning tape on the vent? Might be worth a try. EQ is handy but a pain if you have to swap around sources and IEMs…

[thoohil]

thanks for the reminder…trying it now.

[thoohil]

Fully taping helps a bit you’ll gain around 2dB more sub bass at normal listening level.

The S12 has 2 vents

which I taped masterfully for science

I recorded the same track at same volume 1x taped and 1x untaped. Then I checked the audio spectrum in iZotope RX7. There I looked at the dB amplitude of the first strong bass impulse at around 40Hz.

Untaped (amplitude = -24.7 dB):

Taped (amplitude = -22.4 dB):

So in this scenario I gained -22.4 dB - -24.7 dB = 2.3 dB

and finally the sound demo:

You da man! thanks for all your contributions

@thoohil

haha love it. Have you seen these before? Tuning paper. In case you want a more aesthetically pleasing tape mod haha

[thoohil]

It’s a fun hobby. Thanks for the info about the tuning papers.

[nymz]

Good job S12 is a beast

[Aromato]

but doesn’t it cause pressure build up and suction feeling? correct me if I’m wrong but also it may enclose the sound stage

[thoohil]

Are these air-permeable? Because my first taping test I’ve done was with some random fine pore filter I had lying around which had no effect. The seal has to be tight.

[ttorbic]

Interesting. I think they are somewhat permeable. Akros has a vid on using them to modify bass on Blon BL03, so it does work for that IEM: HZsound HeartMirror - How to modify Bass Output TUTORIAL - YouTube. Not sure if it’s different with planar drivers?
