A lot of dongles do cut off the first 0.1s FiiO KA17, Shanling UA4, iBasso DC06Pro, TempoTec Sonata BHD Pro all do. I'm pretty sure it has to do with the implementation and/or configuration of DAC automute. But: iBasso DC04Pro does not cut off anything. So if this is important to you, I...

Still cutting off the first 0.1s for me, too.

Are you sure that it is v3.22 and not v3.21? Does the app say v3.22? My app says "v3.21 the latest version". And my Google Play Store says "v3.21" as well. @FiiO Could you please comment on the app version in the Google Play Store? Is it v3.22 or v3.21 still? My Google Play Store definitely...

When will FiiO Control v3.22 be available in the official Google Play store?

This is wrong. 1) M12, M12i, M15, M15i all use ES9281AC with integrated ADC. 2) Old M12 does support microphone (but old M15 does not).

@Questyle Could you please comment on whether or not M12i and/or M15i do support in-line microphone?

added various Simgot

Simgot DEW4X does NOT support microphone. http://www.simgot.com/en/products/detail/33.html#!/detail

But how does FiiO KA17 achieve 4.5 Vrms = 12.7 VP-P (4.4mm, desktop mode, high gain) then?

You are talking about Vrms while zilax002 is asking for VP-P VP-P = 2 x sqrt(2) x Vrms

Voltage swing of FiiO KA17 is 12.7 VP-P 4.5 Vrms = 12.7 VP-P

@FiiO Could you please explain why there are 4x SGM 8261-5 amplifiers, when fiio.com states that "inside the KA17 are THX AAA 78+ headphone amplifiers"?

I'm pretty sure neither the filters itself, nor their numbering/order, did change between firmware 0.84 and firmware 0.99, only the names were completely wrong in 0.84 e.g. filter 4 always was "linear fast low-ripple", even though firmware 0.84 said "minimum slow".

To clarify: I'm pretty sure neither the filters itself, nor their numbering/order, did change between firmware 0.84 and firmware 0.99, only the names were completely wrong in 0.84 e.g. filter 4 always was "linear fast low-ripple", even though firmware 0.84 said "minimum slow". Filter names...

Ok, so no in-line controls. And in-line microphone?

Any official/quotable update on this? :)

Another short cable from ddHiFi: • ddHiFi BC130B Air Nyx (Short Version) – 55 cm – MMCX – 4.4 mm BAL

Wow, what a great explanation!

@Shanling Any updates regarding the bad noise floor on 4.4mm output? Easy way to reproduce it: Connect IEM to 4.4mm output. Make sure that any audio is actually playing. Else automute will hide the noise floor. While audio is playing, reduce volume of UA4 to 1. Bad noise floor is clearly...

@ammarali047 Maybe you can get Creative SXFI Amp (discontinued?) or Sound Blaster X1 (https://us.creative.com/p/sound-blaster/sound-blaster-x1) for under 40 USD?

I asked @MOONDROP here, but no answer yet. But I'm pretty sure that Moondrop Dawn Pro does not support microphone passthrough, because CS43131 does not include an ADC. Hm, there are reports that some bluetooth-dongles will do microphone passthrough only in bluetooth-mode. But I will try to...

@MOONDROP Do any of Click 3.5, Dawn 3.5, Dawn Pro, Moonriver2, Moonriver2:Ti support in-line microphone (4-pole 3.5mm CTIA TRRS)?

@Andykong Do Cayin RU6 and/or Cayin RU7 support in-line microphone (4-pole 3.5mm CTIA TRRS)?

@iFi audio Do iFi GO link and/or iFi GO bar support in-line microphone (4-pole 3.5mm CTIA TRRS)?

1) Etymotic ER4SR. iBasso DC04Pro – 3.5mm – noise floor good iBasso DC04Pro – 4.4mm – noise floor good Shanling UA4 – 3.5 mm – noise floor good Shanling UA4 – 4.4mm – noise floor bad :frowning2: Same IEM, same cable, same everything. 2) Then your engineers are wrong. Because the official...
