I like mine. Great sound. But the battery now drains completely every day even with everything turned off, and it’s a major pain in the ass to charge because the USB port is damaged and only works with one specific charger cord carefully balanced in a specific position. I’d be wary about buying...

My micro usb port has gradually deteriorated over several years. Right now, it only works with one specific usb cable... which is really weird, but it's better than no cables working. Assuming there is nothing better in my price range when this one finally stops accepting a charge, I will...

I saw signs of life within about a half hour of charging. Hold down the big power button for a bit (up to 10 seconds) and hope to see the magic words “Powered by Android.” That’s all I got. Don’t know if any other hidden buttons or reset options. Fingers crossed for you.

I’ve had this happen as well. Charging it up should bring it back to life. My charge port isn’t super reliable—some cords only work if the unit is carefully placed in a specific position. Not ideal. But it’s super terrifying when I accidentally run my unit to zero because I can’t see the charge...

It might depend on what app you use to listen to music, whether the music stops when the cable is removed.

My experience with the 300R's wifi is that it is pretty bad. It almost always requires me to force it to connect to either of the two routers I use the most--when I get to work, I must tell it to connect to the work router; when I get home, I must tell it to connect to the home router. Almost...

I wonder whether it would be worth finding a truly flush 90-deg micro USB adaptor cord and attaching it--then only charge through it, to minimize wear on the actual USB port? Something like this, though this isn't exactly right... Slim Flat Micro USB FPV Flat Slim Thin Ribbon FPC Cable Micro...

There are photos where someone did the epoxy thing upthread somewhere. I don't have time to search it up right now, but it's there.

I was recently seeing unusually fast drain. Had to uninstall Spotify (no big loss for me) and it's back to only draining significantly when I listen to music. Search this thread for me, and you'll find some battery-drain data from awhile back--that's basically what I get now (after axing Spotify).

See post #1915 from November.

It's probably not for everyone, but I keep mine in this pouch, and it works great. Easy access to either the volume wheel or the transport buttons, loose enough that it hasn't suffered any damage after several drops, a few pockets for cords. I did use an x-acto to remove the velcro and...

I find that the Bluetooth radio in the player is poor. It drops my headphone connection when the player is in my front pants pocket outdoors. Range is slightly better indoors, presumably thanks to reflections off the structure. You may be able to find a location for the player that gets you...

I'm on Linux and not super competent. I just pull the cards out and copy files with a USB adapter when it's time to add stuff. I don't know how to access the cards when they are still in music player. (Should see what happens when I connect the player and look at it in a Win 7 virtual machine.)

I heard pops and glitches when I was trying to listen to music while UAPP was updating its database. Everything was good again when the processors could focus solely on music. Maybe make sure you don't have anything unnecessary running/updating/downloading? Just a thought.

I haven't had any problems with the headphone jack. I try to be gentle with it, out of an abundance of caution. So far, so good.

Can someone please explain to me if I might derive any improvement in sound-quality/audio fidelity with the 300R if I stop using the Onkyo app and switch to UAPP? Assume my ears are as good as oscilloscopes (though they aren't), and that I don't know anything about PCM or DSD or FLAC or really...

Search this thread for zombicube. I posted results of a few battery-drain tests earlier this year. In my normal usage (flacs and podcasts on unbalanced headphones, screen almost always off), I measured drain of about 6% per hour. More recently, I have been running the AccuBattery Pro app, and...

I don't know much about Android because I mostly live in the iOS ecosystem. What are the characters that the android OS doesn't recognize? My flac rip of the "Black Panther" soundtrack CD didn't show up in the player until I deleted a colon ( : ) in the folder name on my micro-SD card. What...

Yeah. My Wi-Fi acts up also. Agree it's annoying.

I have a tagging problem with Neutron, where it looks at the wrong metadata for Artist. Example is U2 "Joshua Tree" album, which all other apps sort with U2, but Neutron sorts with Brian Eno as Artist. I think Brian is alphabetically first as one of the artists on the album in the MusicBrainz...

Just the latest.

I spent some time this week measuring idle battery drain. During the tests, the player was sitting on my desk at work, intermittently connecting via wifi to look for podcasts, Bluetooth off, screen off except for quick checks of battery percentage at ~half hour intervals. I checked drain from...

Questions about the failure mode involving the headphone jacks. (1) Has anyone had this problem happen recently, i.e. with one of the units ostensibly manufactured with sturdier jacks? (2) If so, when the unbalanced jack fails, does the balanced one still function? I.e., does it make sense to...

Update on my battery test upthread. Ran four hours under the conditions cited above, checking the battery percentage every half hour. At one point during the test, podcatcher downloaded 2 episodes in the background while the music player was playing flac off a card. Over the 4 hours of test...

Not a big deal. There's a graph in the stock battery app, but I can't figure out how to use it in a meaningful manner--can't zoom in or see axis labels. But a few rounds of half-hour checks should give me a decent trend. (Materials engineer, also a ham AC2VO.)
