Sony Walkman Bluetooth 64GB MP3/DVD Player, Black, NW-ZX707

I am again grateful to Sony for releasing this product. It's an enjoyable experience. I had the NW ZX-507 previously but the larger screen & updated form factor of the NW-ZX707 make it feel like more than just an upgrade to that player but in a different class. 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.

I like all but one feature on this DAP. The sound volume is crippled without the high gain feature. With bluetooth headphones the volume is great. With wired headphones/earbuds the volume has to be at or near max to enable proper listening. I hope Sony will fix this with a future firmware update.
