I guess I am not a purist in HiFi; Sometimes I like to listen to "Modified HiFi" !!! LOL, Depends on the music, and depends on where I am, depends on the device in my ears! If it sounds good and I enjoy the music, that's enough for me!

I've used adapter like this to hold a small DAC Dongle to my phone...

Agree, I do think that some (Maybe a lot) or higher res recordings are actually Better Actual Records and Get Better Studio Processing Quality; Which can also 16/44.1 sound better. But a lot of CD's were made from poor Recording Quality Tapes, and Poor Studio Editing. So Higher Res often do...

I Remember MEIZU, a Chinese MP3 Company went from making MP3 Players, to making Phones. So Moondrop will not be the first to try this. Looks Meizu still makes phones, but don't see a 3.5MM Jack in photos or specs. https://www.aliexpress.us/item/3256806094713180.html I Also remember that 5+...

My 16/44.1 FLAC music files are lossless, and they range from 700 to 900kbps. WAV @ 16/44.1 would need more bits, because it includes bits when nothing is there, where FLAC is Lossless, but removes any unnecessary data. So, 16/44.1 FLAC files should be easily able to be sent LOSSLESS with...

Hmm, The link and lower price do show up for me. Maybe regional? I am un USA.

These may be great IEMS, I have not heard them, But for some reason instead of seeing "CRA PRO" I keep seeing "CRAPO"... LOL

Tidal was designed for the Android based devices. As the Hiby is not Android it is LINUX based; So a custom interface is needed; and that interface does not allow all TIDAL Functions. Believe this is a Tidal Limitation for non-android devices. (This is all that tidal licensed to Hiby for LINUX...

Sorry, did you explain somewhere what happened to your 5K? What is it doing or not doing... Did this happen after a firmware upgrade or something? Or ??? - Difficult to offer advise without knowing anything but your request to g back to v2.x.x firmware. I looked for any previous messages...

Hope your new W4 solves your problems! However, If your jack is slightly (not visibly) corroded, it can reduce contact quality and put extra stress on both the male and female connectors. Caig Deoxit G5 Gold, is one of the best products to remove minor oxidation, and provide a conductive...

The screen is 4.7 inch diagonal, so size of the entire unit can be estimated... That is the only dimension I have seen. Those colorful "bumps" look to add some thickness; But unsure if that bump is needed for some internal components, or just for looks.

If you remove your microSD card, Then do the Factory Reset, then there will be no change in the MicroSD card, And the music files stored there. Any Music on Internal memory might (or might not) be affected by a factory reset. After the reset, re-insert the microsd card. Another...

Sorry if you've already checked this, but Wonder if your Sandisk Extreme Pro 1tb could be a fake? It might "appear" to be good and show the file structure in windows, but not on other operating systems because it was only set up to appear real on windows? Can you actually play files from that...

Agree. Sometimes even a single "font, character, or symbol" in the file tag can result in a scanning error. Can't explain why some Apps will scan and others will not. Maybe some APPs have a larger "library" of characters that they recognize and sort by?
