Android phones and USB DACs

No transports do sound different, are you using the same Android version?
both phones using 5.1.1


Try installing build.prop editor and reading the contents of build.prop (this shouldn't require root). There may be a key under "Unknown" called "af.resampler.quality". Let us know what the value of this key is set to?

Or if your don't mind waiting a month, these are great. I use them with my Vamp Verza.

Anyone here tried the new Dragonfly/s? I love the form factor of the first and used it a lot with my phones despite the power draw, keen to try the new ones.

Never heard the old Dragonflies but I use the Red with a 1st Gen. Galaxy Note running CM 12.1. The phone has been repurposed as a dedicated DAP and serves no function other than audio player. No SIM card, no WiFi. Just airplane mode, USB Audio Player Pro and music. Battery drain is about 1%-3% higher per hour than through the phone's headphone out using Viper4Android Super Audio Quality driver, and I have never run out of battery before getting back home to charge. Going by the built-in battery meter I'll get around 8 hours of continuous playback with the screen off. It's not great battery life, but most high-end DAPs have similar run times.
 
On my Galaxy S6 Active the drain is slightly more. Around 4%-6% per hour but I've never tested it just sitting around in airplane mode, so LTE, GPS, etc. are still active. The Red is pretty powerful, too. Now I can amble about my apartment with the Q701 while dragging a 10-foot neon green cord behind me and not worry about sacrificing sound while I'm chopping onions.

Firstly, I am sorry if this is a stupid question and this is the wrong place to ask it (I have searched Google extensively). I was wondering if there is a mini device that would plug into the USB port on my phone and allow me to bypass its volume control and instead adjust it with the device? In other words, instead of the volume being limited to 1-15 steps, I could finetune it with the device. I'm not really concerned about the amp and DAC, as the one in my phone (LG V10) is already very good. If there is such a device, I would like something as small as possible. Thanks in advance for any suggestions.

Then I would suggest that you root your V10, install Xposed framework and then install VolumeSteps+. This lets you have any number of volume steps right on your phone. I set mine to 150 steps.

any dac/amp with a physical volume control, search it up!

Thanks but unfortunately VolumeSteps+ doesn't work with either of my phones (one because I can't root it and the other due to something with the audioeffect.apk).

Thanks, but I was hoping for a recommendation. Something as small as possible that won't colour the sound signature of the phone too much.
