I do just use with my own flac (few MQA/DSD) files or Tidal Offline tracks and battery life is great with WiFi off. Just use Sony Music app and Tidal app, nothing else on it (apart from Spotify too).

I've had ZX300, ZX507, WM1AM2, WM1ZM2 and now just my A307 and its longest I've kept a DAP. Not missing balanced at all though I am using with balanced cables via the 3.5mm to 4.4mm seperate earths adapter cable (mostly as I prefer the cables and use with another 4.4mm source too). I do have...

Of course, not relevance on an uncapped one like my Japanese version. Never get the nag warning at all anyway.

Mine still looks brand new, but I do handle all my stuff carefully, and no drops.

At £450 for just a DAC/AMP I would hope so! I think my Fiio BTR7 with my smartphone sounds better, but then its not a small, convenient all-in-one Android DAP.

DAC is only one part, you have to consider the whole and then tuning on top of that.

Well, I liked the Hiby R5G2 but kept my Sony A307 (A306). Android OS in Hiby a bit too old but sounds great. Sony a great size, Android 13 now and great battery life with WiFi off for offline streaming music use or your own files in Sony Music app. Sounds great too, but my Fiio BTR7 has the...

And often it's not 5% more, just 5% different. I went all the way to a 1ZM2, then dropped to a 1AM2 and now perfectly happy using either my A307 or my Fiio BTR7. Spend your big money on the IEM's for the stepped improvement in SQ IMO. My next purchase is likely a Mojo2 after having owned a...

Mine seems to only charge to 100% if powered off when charging (or it goes off). Seems to need Android OS on to work.

They can sound different though as I believe the Sony Sound Options/EQ have an effect over BT too. I use my A307 in Direct mode and for BT I use my S23+ instead as sounds same at same codec/bitrate and more stable on my S23+.

Confirm my Japanese A307 has Playstore

Why 'better' for TWS? For TWS might as well just feed from a good android phone over LDAC. There isn't an IEM my Japanese A307 hasn't done justice too, inc IER-Z1R & M9. It's longest I think I've kept a DAP as size, battery life, functionality from streamed audio and sound quality spot on...

Only downside is OS is still a bit sluggish for some 3rd party apps (not as bad as WM1ZM2).

No, went smooth & quick for me for my Japanese import A307.

There is no such thing as Best, it's all individual down to our individual ears, likes and tolerances. I can't bare any foams where they are squashed then open up inside ear with pressure like a factory earplug, just prefer light contact of silicon.
