Are majority of you on the 2.0.1 firmware or are you still sticking with Version 1.4.2? I do not have anything that supports Bluetooth 5.0 yet, so wondering if it is worthwhile to upgrade to 2.0.1 as it is not possible to downgrade anymore.

I can't speak for others, but it appears that startup time has been shortened, which has been a positive for me. Double-precision equalization processing probably has improved objective quality, but my hearing is too chronologically-impaired to hear the difference - has someone else noticed, or measured?

I have no regrets.

Thanks - that would be a positive for me as well. Time to upgrade methinks.

I Used the device like 2 hours before i updated to the latest firmware 2.0.1,

The 2 hours were great, after the update it is still great but Using LDAC connected to WM1A, I got around three dropouts per an hour but they are very small, less than a second dropouts.

I see others had the same problem after update, I still can't decide if its annoying enough for me to revert to old firmware or not, but anyway i hope they fix it soon

from their website :

"Warning
From the firmware v2.0 or later, ES100 supports Bluetooth 5.0 specification. Firmware update with the latest version v2.0 or later is available, but please note that reverting back to v1.4.2 or before is not possible. Once you have it updated with v2.0 or later, DO NOT revert the firmware back to v1.4.2. The device will be bricked."

@kingdixon be careful and double check what you are doing before reverting - Radsone said that if you're on FW 2 and later, you cannot revert to FW before 2 (so 1.x.x), or you'll brick the device

errrr, Thanks for the note !

I think most devices put such warning and nothing happens when you revert, but i wouldn't take the risk anyway ..

Will just wait for their update, i just hope they got our feedback about the dropouts.

I do recall after updating that I had a temporary issue with LDAC on my Sony Blu-Ray UBP-X800 player in "Audio Quality" mode (990 Kb/s); it wasn't dropouts, though - it was some kind of warbling distortion. I switched to AAC on the Sony and had no issues.

Later on, I was noticing some unacceptable latency while streaming Netflix on AAC, so I tried LDAC again. It's been fine ever since. I can't say that the 2.0.1 firmware had anything to do with the earlier issue; perhaps it was a coincidence.

I do have a few other devices nearby that are broadcasting in that crowded 2.4 GHz band (my main ASUS Wi-Fi router, Xfinity Home Security router, Amazon Echo, Philips Hue hub, etc.), so perhaps there were some temporary issues negotiating a decent connection with the Sony. I'm going to see about moving a few of those devices further away from the Sony Blu-Ray player; it may have a less-than-ideal internal antenna setup.

I haven't followed this thread in a while but I made a desktop mount for my ES100 and thought I'd share if anyone was interesting in printing one.

Hi

I want to get this to replace a Chromecast Audio dongle for Qobuz and Spotify LDAC BT reception from my new Fiio M9.

Will there be an issue with having it attached to power (I presume micro usb) full time?

Or should I look at another device?

Many thanks

Couldn't find a right angled 2.5mm balanced plug that is small enough to my liking. So I settle with the smallest straight one I have and mod'ed it to the short FiiO mmcx cable.

I agree, the ES100 app and EQ control is really what did it for me. I didn't just want a bluetooth adapter for my IE80's, I wanted to have full control of the EQ at the DAC level. The wireless is just a bonus. I'd get the ES100 but I could be biased.
