Removing the headphone jack on phones like this is another example of Android phone companies copying questionable Apple designs into their phones. Google claims that USB-C delivers higher quality sound than the jack. That's bogus. As with Apple iPhones, removal of the jack means the phone doesn't need an internal DAC for analog sound delivery. You have four alternatives: buy bluetooth headphones with onboard DAC and sound latency (depending on signal strength); find a USB-C headphone with quality reliant upon DAC(s) in the headphone; buy a USB-C to 3.5mm dongle with DAC in the dongle for use with wired headphones without internal DACs (most high quality wired headphones are in this category, depending on signal delivered being analog); buy a USB-C dongle to deliver digital signal to an external DAC, either in the wired headphone itself or as a separate component. Most sound aficionados looking for portability prefer phones with high quality internal DACs delivering an analog signal through the 3.5 mm jack, hopefully to end up via a wire to top line wired headphones. Latency is minimized, the DAC is of consistent quality as specified in the phone design (don't need to worry about variable DAC quality in various dongles and/or headphones); and there is no worry with charging headphone batteries and/or phone batteries. A phone with a jack can be charged independently of the sound being piped from the jack to the headphone. If you're on a long plane flight, for example, you can charge your phone while still listening on your wired headphones which have no batteries to be charged. It's a dead horse with Apple, as they'll never backtrack on removal of the jack. So far, companies like LG still design phones with high quality sound production as a priority. There may be others of which I'm not aware, but LG V20/30/40 phones deliver superb sound to wired headphones. For sound, they're even superior to the 6S/6S+, the last iPhones with jacks. The LG Vx phones have better internal DACs (I've purchased both a V20 and a V40 since my last iPhone purchase - a 6S+). Unless Apple produces a relatively cheap iPhone (< $500) I likely won't buy another. I'll hold onto my 6S+ until it croaks or is no longer supported for battery replacement.
