Mine rattles, too. It works fine, so I've just ignored it.

I'll second this. I was listening to music through this setup when I read this post. There's nothing like them for the price, and the headband is more than worth the few dollars it costs. 

Two things that I'd check. One, in Developer options under Select USB Configuration, do you have MTP checked? I do, Audio Source also seems to work. You could play around with this.   Different root methods (and SElinux mode, enforcing or permissive) can affect whether system audio changes...

It's working now, DFB is lit green in Spotify and it sounds great. The only thing I did different this time was to reinstall V4A after making the change in audio_policy. I only changed the sampling_rates line, not the two below it. Do you think the other two make a difference?    Youtube even...

When I have time I'll play around with it some more, there are a couple things that I'm thinking may be involved. Will report back if I get something working. Thanks.

Strange results for me. I tried your suggested changes and also tried only changing the sampling_rates line as west0ne suggested. Dragonfly light turned green, but sound wasn't so good to my ears. Sound (especially highs) was really sibilant and tinny, extremely so. I do have V4A ARISE...

I'm very interested in trying this. In audio_policy.conf I'm seeing a few things related to usb device, not sure which one(s) to change. Would you take a look at my screenshot and let me know what you think? I'm rooted and used to making changes in build.prop, so I'm comfortable with the risks...

I've just started using this with a Dragonfly. I have playlists from another player that I'd like to transfer to UAPP, and notice that UAPP playlists are .xml files, while my saved playlists in other player are m3u8 files. Is there an easy way to convert m3u8 to xml so I don't have to create new...

Thanks for answering. I must have missed that because I had the uapp hardware volume set too high and thought I wasn't controlling it with my phone's volume button when set to hardware. It was loud! Working now.

My DFB arrived, it's running and sounding fine on my Nexus 5, definitely an improvement for my harder to drive earbuds and ath-mx50. There's a learning curve in getting volume controls figured out and getting it to work with Spotify.   The sound on my desktop set up through DFB is blowing me...

Any Nexus 5 users here with DF? My DFB will be arriving soon, please let me know if there's anything I need to be aware of. I've ordered the dragontail and know about UAPP, anything else for N5?  Thanks.

My AuGlamour arrived yesterday (Amazon), and my impression is also good. Without having seen ClieOS and vapman's reviews, my early impression also put them near the Cygnus. Side by side the AuGlamour is warmer and less detailed in higher range. Definitely a fun and musical sound. Stiff, rubbery...

I'm using a simple V4A profile that you should be able to set up in minutes. I've tweaked the eq according to the suggestions in Brooko's review posted a few pages back, and I'm slowly adjusting them to better suit my preference. I've also played around with a few .irs/convolver settings, the...

Thanks! This is just what I needed, especially the graph and your suggested eq tweaks. I've loved the monks from the start but had a hard time with certain frequencies, and didn't know which ones they were.  My ears aren't good enough to know "geez, everything around 62hz is really bothering me...

I have both. Regarding price I'd say Monk+ is a $5 earbud that sounds like a $15-30 earbud, and Yuin PK1 is $100+ earbud that sounds like a $70-100 earbud, depending upon whether it's amped or not.   Both on the warm side. I think PK1 is more balanced, much more clear (but could be better for...
