Man, I'm sure glad that I've got a unit that plays music straight forward the way it's supposed to and just lets me enjoy it.

Also, complaining about that a device respond in a strange way when doing things with it that the manual (or maybe it's the app) clearly state you shouldn't is pretty ridiculous imo....

So I've tested the second unit. It is NOT design flaw - the second unit also has disbalance, but now it's right one slightly louder.
I guess that units were not properly calibrated for a balanced mode. So adding analog balance into settings would be beneficial for sure...
If I have correctly converted voltage to SPL - that is the result:

The magic dip is at 10080 Hz.
If my calculations correct - SPL difference of L/R is 0.06dB. Which is probably NOT what I hear.

I need to test on a proper oscilloscope tomorrow. There is probably phase issue between channels.

No channel imbalance issue here with my ibasso it01s via 2.5mm balanced and I listen to music at least 6 hours a day at work.

The device behaves strangely in some instances.

When I turn off my bluetooth while playing music the device freezes up and won't respond to attempts to turn it on again.

When I disconnect my headphone from the 3.5 mm while playing music it also exhibits the same behavior.

I understand we're not supposed to do either of those things but I make mistakes sometimes and it's not fun to have my device become useless until I can get to a computer and revive it.

@madmissileer:

Thanks for the reporting and I'll check the issue.
Meanwhile, I suggest locking the output mode.
That will help ES100 be safe when plug/unplug 3.5mm jack.
Thanks,
WS

How is this feature set? I am not finding an option in the Android App: Auto power off on USB charger connection (optional) added. I have successfully upgraded to firmware version 1.2.0

Edit: This feature is set by clicking on the battery icon in the app.

Thanks for the regular firmware updates, Lee.

This is now my go to DAC/AMP because of the connectivity options, reliability, size and basically good and clean sound.

@subtec:

ES100 doesn't support AptX-LL(Low Latency).
Instead, we're considering providing a buffer length option for trading-off the latency vs. the stability.

Shorter Buffer length (Aggressive, may not be safe in poor RF environment)
vs.
Longer Buffer length (Moderate, Safe streaming)

We're expecting the buffer length option would be useful for those who don't have AptX-LL encoder and have stable RF environment.
The latency can't be shorter than AptX-LL, but at least you may be able to shorten it than the current.

Thanks,
WS

I'd like to request this buffer adjustment feature for the app, if it's at all possible to add.

Not planning to do it regularly but it would be nice to know that I can reset the device when I mess up. Took the device with me but turned bluetooth off by accident, and was stuck without music for the day as I had no way to reset the device until I got back home.

Thanks for the reply. I locked the output and the headphone jack problem has disappeared. Hope you can look into behavior when I turn off bluetooth during music playback and device is unresponsive. I was only able to use it again after entering update mode by connecting to the computer.

I just picked up my ES100 from an Amazon Locker (using while I'm temporarily relocated for work) and am charging it.... can't wait to update the firmware and try this thing out!!!!!

@madmissileer:
Currently, we're trying to figure out the solution.
Can you be a beta tester?
Please contact support@radsone.com, so that we can get to you with a beta F/W.

MacBook users,

We've found the v1.2.0 DFU package had a problem with MacBook and uploaded v1.2.0b again.
Please download v1.2.0b and try DFU again.
Thanks,
WS

So far, after reading all the reviews, I'm wanting my self to get one. Too bad no shipping to Hong Kong from Amazon. @wslee when are you going to start shipping outside of US? Thanks!
