Customer Reviews for Sony NW-ZX707 Walkman ZX Series Hi-Res Digital Music Player with Bluetooth, WiFi, & Expandable Storage
It would be great if the combability can improve with iPhone. Although, ZX700 is android based, can easily install streaming apps, I would appreciate if it can serve as DAC for iphone. I have tried the DAC mode with my iPad Pro with USB-C port, it work fine. Unfortunately, when I plug-in the lightning otg cable with my iPhone 13 Pro Max / iPhone 11 Pro Max, my iPhone showed that ZX700 uses too much power. I have look for any setting to solve this, seems no options for ZX700 not charging from the iPhone connected.
I have asked the professional portable audio gear stores, some other clients have the same problem and cannot resolve. This combability issue is not purely Sony's problem, but I hope option for "not charging from connected device" would available when connected to iPhone as well, or some other ways to solve this problem in coming update.

Sound
I do not use IEMs, I use headphones. I tried this with the Sony MDR-H600A (Wired to 4.4MM Balanced - Sounds great), the Sony MDR-Z7M2 (Wired to 4.4MM Balanced, these are 70MM - required about 90 on the volume but it works with this device). Master & Dynamic MW65's on Bluetooth. With all of those, this device sounds excellent. Tried a few genres, Jazz, vocal & EDM genres. I would like to see in a software update a few DSPs (or at least presets for the equalizer)
Battery Life
I can't imagine getting the full 20 hours, but in the 12 days since I've had this I haven't run out of battery during the day. What I have seen is that using the 3rd party music app (i.e. Youtube Music / Spotify) will use more battery than the stock music app. There is a setting to restrict background operations because if you install 3rd party apps then those could consume battery.
Screen
I like the screen when playing Youtube music, it looks good. You can't compare it to a phone because it has it's own look.
Size
It's a bigger/heavier device than a smartphone. Feels solid.
Conclusion
This is for someone who wants a dedicated music device & has a collection of HiRes music or uses a HiRes streaming service such as Qobuz. I personally have owned devices from other manufactures & would recommend Sony because it just works better. An example would be how a competitor's device's WiFI was slow because it did not work with 5G or how their bluetooth didn't have enough distance. These are things that just work correctly on the Sony players.
