Quick update - for everyone who's experienced issues with the XD-05 in USB mode - driver load failures, distortion, and cellular interference like DetonNation's having - many of them are caused by the crappy USB A male - female cable included in the factory packaging Monoprice sells a short (1.5 foot, 46cm) version of this cable for 3 USD (Monoprice #13749) - it fits snugly without any slop , cured all my USB errors, and eliminated RF hash coming from a nearby WiFi router - it's a surprisingly cheap and effective fix. For International buyers, the same cable is sold by Amazon - search for 130713 cable - which is otherwise stupidly difficult to find.... Cheers Jim

Yes, my phone randomly disconnects, get static, and I'm using a different cable than the stock one provided. Any insight as to why this might be happening besides shoddy wire?

IMHO - these sorts of problems almost always trace back to a connection fault. If your new cable fits the Xduoo well, then suspect the phone's micro USB connector - this design is a mechanical shitstorm with an undersized center conductor surrounded by an easily deformable metal shell that's just not going to stand up to an angry monkey jamming a cable in bass-acwards... There are tweaks to restore the connection - search for 'micro USB fixes' & there are some good videos. Or, bite the bullet and buy a phone with a USB-C or Lightning connector, both of which are mechanically far superior to Micro USB-A. Jim

What's weird is I do have a USB C phone and cable, and I found the only way to fix it is to turn off the xduoo OR change the input using the toggle switch back and forth. So I'm having the connectivity issues even with USB C, anyone else? Using a One plus 3t

Yeah, this is odd - but it still sounds like the XMOS chip is getting overwhelmed by noise or excessive dropouts so that its ECC fails, looses tracking, and then needs a reset. If you're using a USB C to USB A Female cable, then you've got a good mechanical connection and decent grounding throughout. The OnePlus One 3t uses USB 2.0 over a C connector, so it shouldn't have any compatibility issues with the XMOS chip - although I've found that the XMOS seems happiest if you restrict your digital gain to less than 50% scale, and set the listening level with the Xduoo's analog pot. Otherwise, you're in for an RF noise hunt - start by stripping back the phone's RF signature - NFC =OFF, Bluetooth=OFF, WiFi=OFF, and Airplane mode=ON should be a good starting point. If this cures the problem, then slowly re-enable services in reverse order - if disabling Airplane Mode brings back the farts, then suspect that one or more of your carrier's bands are interfering and try to work around by disabling individual access points until you run out of access or the problem goes away. This is a slow, painful, hair-tearing debug process - but unless you know someone with an RF sniffer and a spectrum analyser I really don't know a better way... OTOH - someone posted a Bluetooth 5.0/APT-X adapter that plugs directly into the XD-05 - it seems to well thought out and may solve many problems fairly cheaply - I found one link here: https://penonaudio.com/xduoo-xd-05bl.html Jim

some really sound advice, thanks mv. forgot to mention, while I do get static (which could be from the other radio services interfering), I am having issues where the audio just cuts out. The only fix is to reset the XD05. not sure if it's a firmware thing or not

No worries. I meant just turn it on/off again, not an actual button sequence to fix it. Don't listen to me, not a repair guy, but if you're experiencing static you can try using a different wire. if you still hear it, try using another usb device. if you still hear it, it's your actual dac/amp causing the issue. if that's the case, you can probably open it up and spray some deoxit or equivalent. basic IT troubleshooting method. hope that helps bud

PC38X microphone volume too low
How can I increase the volume of the microphone of my PC38X? On my new Lenovo X1 extreme with Windows 11 the sound for my listeners is too low and I've tried everything available on Windows 11 and related drivers for the Realtek Audio 'card'. I've found a way to boost the volume using Sonar of the Steelseries GG Software. What other options would you advice me?

To slow for drop.
Man drop brought back the 789 and the balanced grace dac but was gone in a flash. Anyone know how much they were selling the balanced grace dac this time?

Best Headphones (without DAC) under $150
Hello folks, I've been following this blog for a while, and after a really long time, I've decided to get some nice cans. I am a student, so I don't think I can go higher than $150, and I don't have a DAC. I've researched on the following headphones- Beyer DT 770 80 ohm, AudioTechnica 50MX, Meze Noir, and some Senheiser models. As of now, I am leaning towards the DT 770's. Any recommendations as of 2022 on models I should check on? Any solid options?

Having Issues With Lack of Support From Customer Service and Missing Item
Hello everyone, I am here because I do not know what else I can do at this point. For a little background, I purchased a headset back when Drop had their competing Amazon Prime Day sale. It was my first purchase ever from this company but I saw a good deal mentioned by a YouTuber and made the jump to purchase on sale. The product was definitely not cheap ($419) but in comparison to the cost before sale ($529), I thought it would be worth it. Fast forward a few days, I get a notification that shipment from carrier (UPS) would be delayed. I did not think much of it but followed up with it and update stated delivery scheduled to Friday, two days later than what was originally scheduled. Friday comes but no package. What's more concerning is that when I checked my email, Drop sent me something saying it was delivered Thursday. Apparently, the carrier changed from UPS to USPS without any explanation or notification as to why. Concerned, I asked my neighbors and leasing office if anything...

Did you guys see the CYBERBLADE from Angry Miao?
I saw that on their website today, I am just curious are they legit? Not a big fan of their keyboards, but will probably give it a try on earphones if it is not too expensive.
