How does it fair compared to BTR3? I own a BTR3 Bluetooth amp but im not satisfied with its performance (I listen to Spotify & Apple Music).. Would this Radsone es100 be an upgrade to BTR3?? Suggestions are welcome.. thanks

Audio quality is excellent. Using it on a phone via Bluetooth, it powers a Beyerdynamic DT 880 250 ohm well. However, as a computer DAC/amp, it doesn't have enough power (for a powerful sound). Is there a way to fix that, or is the device battery always off when connected by USB?

OK, the pre-amp in the equalizer can be set on the phone to increase volume even in USB mode. Cool.

In daily use of this device I have found a small super-annoying design choice: when attaching micro-usb charge cable, the unit powers on. When disconnecting the cable, the unit powers off. Which is idiotic. Here's what happens: The unit is powered off and is low on battery, so I connect it to a chager. Units powers on and pairs with my phone even though I'm not using the unit. Phone rings - and I wonder why I hear nuthin'. Then I realize my call goes to the Radsone which obviously I'm no using since it's plugged in for charging. I'm on a long Teams call and Radsone gets low on battery, so I connect it to a usb cable to get juice. All good so far. A bit later Radsone has battery so I disconnect the charge cable...which powers the unit off and throws me out of the online meeting. This is idiotic - what were they thinking? A&K XB10 got this one right... hope Radsone fixes this one.

Hey, you can turn that off using the EarStudio companion app on your phone. After connecting the ES 100 to your phone, on the main page, tap on the 'battery' bar. Under the 'charger mode', select 'auto power off' option. I hope this helps.

The green ring in front flashes on/off continuously, is this normal?

Yep, that's perfectly normal. If you don't like the blinking, you can switch it off via the EarStudio app on your phone. In the app, tap on the Radsone icon on the top left corner of the screen, look for 'misc control', and it should be under the 'LED option'.

I got mine for little more than a week now. It's amazing. Sounds great, battery is good and the app is amazing! Pairs perfectly with my se846's. No perceivable floor noise when properly set up, sounds better than my OP7 Pro when using usb type C to 3.5mm adapter. The only thing that would make perfect is if it had USB type C port.

I have one and love it. I use it as a USB dac on my desk, connected to a schiit magni 2 amp, and on the go to drive my iems. Yes, sound quality is better than directly from my phone or MacBook. And the mic means that I can answer calls. This is a great, great device.

I do not really understand the usefulness of this device but can it improve the audio output on the headphones of my HTC ONE M9 considered one of the best on the market?

Update 10/10/2019: After 10 months of use my ES100 now only connects for several seconds and then disconnects. I see that this is not the only such report, so I guess this product has very limited life expectancy. I can't recommend it any more. My previous review of this product is here: https://drop.com/buy/radsone-earstudio-es100/talk/2472840

Yeah seems like QC is not the best it could be with this product. Hopefully this recent batch with Massdrop is QC'd better.

If you consume music on the go you - just buy it. I bough it from Amazon more than a year ago - best $100 spent in my audio journey.
