I took out my pixel 3XL dongle tonight to test it because I sold my pixel 2XL and was packing up one of the two 2XL dongles I had for the new owner. I noticed when I unplugged the new dongle that it didn't make an electrical popping noise through earbuds like the 2XL did. I also noticed that the connector end with the DAC was shorter and the same size as the charging cable connectors. I tested both dongles but did not notice any difference in sound so I'm guessing they just improved it to eliminate the static click when unplugging it because it might have been annoying to some people especially with the volume cranked up. My other dongles made by HTC and Razor also do not make that clicking sound so it's all good. If you want a better dongle for your pixel then the OEM dongle, the HTC which is slightly better sound. Of course that's subjective and you may prefer the pixel dongle. For an amazing audio experience try the Razer dongle has a lot more kick and full of sound than the Pixel or the HTC
