I have a hunch why many people are hesitating to buy. The entire thread here is full of praise that the Enigma is the best IEM someone has heard so far. But there are hardly any comparisons with other TOTL IEMs. That seems very strange. I've been reading along here for some time and am eagerly...

@JasonNYC , will new battery settings like disabling charging in USB DAC mode or to stop charging at e.g. 80% also be included? As already discussed here in this thread. That would be very helpful

After the factory reset (firmware 1.12CM) and installation of the older Qobuz version 7.13.0.0 suggested by SE300 under "Downloads" and using the non-"emulated" storage locations for Qobuz offline files, I no longer have any dropouts in Qobuz offline mode. With the exception of one 192 kHz...

Yes, I have tested all Qobuz versions between 7.12.x and 7.14.2.0, and I also have the latest SE300 firmware update 1.12CM. I have just reset the SE300 to factory settings, installed the Qobuz version 7.13.0.0 suggested under "Downloads" and downloaded 2 high-resolution albums. The first test...

I will reset the SE300 to factory settings again and test the Qobuz version 7.13.0.0 offered by A&K. Can anyone tell me if there is a difference between the two internal storage locations offered by Qobuz? Thus between /storage/emulated/0/... and /data/user/0/...? Are different Android APIs...

I'm using internal storage but have also tried sd card. And I have to note that I'm using line-out (4V). But is it possible that this consumes so much cpu that it affects Qobuz playback?

I listen with the SE300 (latest firmware) almost exclusively with Qobuz in offline mode and with WLAN switched off. But I always have short sporadic dropouts. It is better in online mode or in Roon mode, but WLAN consumes a lot of battery power. And I haven't had any dropouts in Roon mode yet...

May also be that the battery needs some initial calibration. Just discharge until it shuts down, let it off and let it charge to 100%. Afterwards I would configure the M17 to stop charging at 85% to enhance battery life. But from time to time a calibration can be useful for correct battery status.

Hi @JasonNYC , this would be great 👍 Another related feature request is being able to change all sound related settings in USB DAC mode (NOS/OS, Class A/AB, LO voltage, equalizer). Currently USB DAC mode has to be terminated for each change.

I would suggest the Symbio F tips. For my ears, they are foam tips with sound characteristics of silicone tips. Symbio F ear tips

Hi @Matez , what is actually the correct product name for the new flat 8-core hybrid IEM prototype cable? And will it soon be officially available to order from your web store? In my opinion, with this model you have an absolute TOTL IEM cable on the market that can also compete with the far...

I would like to tell you a little about my experiences with Matt and his cables: I have bought several cables from Matt over the last 10 years and have always been very satisfied. When I started with IEMs a few years ago, I also bought the two Copper and Hybrid IEM cables available in the store...

Hi @JasonNYC , I would very much appreciate the following features for extending battery life in a future firmware update: - Switching off the battery charge in USB DAC mode - Switching off the battery charge at a predefined value (e.g. at 80%) Both features have been available on the FiiO...

Thanks @agrosash and @JasonNYC. I found it at the bottom of the device on the thin silver border. And it matches the serial number on the original invoice :slight_smile:

I have now received my used A&K SE 300. However, I can't find a serial number on the device. It is neither printed on it nor can I find it in the settings. Is there a way to find out the serial number?

I am currently waiting for my SE 300, Since I also own the Cayin C9, which of the SE 300 settings affect line-out operation? Only NOS vs. OS? Or also class A vs. class AB and high vs. normal gain?

Dear @FiiO , Could the technicians reproduce the behavior as shown in my videos? Thanks & Best regards, Matthias

Hi @duffer5 , did you watch my videos, and do my observations match yours?

Thank you very much. I am looking forward to the answer :relaxed:

Hi @FiiO , sorry for the late reply and thanks for the support offer. I have analyzed a bit more with Fiio M17 Roon and found out the following: The problem only occurs when navigating within non-48kHz albums. I was able to reproduce the misbehavior at all sample rates other than 48kHz. An...

Which shows once again that the evaluation of ear tips is very subjective and depends on your own ear and hearing perception. The only thing that really helps is to test them yourself and with your IEM. That is the reason for my grown collection of tips.
