I have both, and usually use them with Sony 7550 IEMs.
I think the biggest improvement the F series has over X is the almost non existent background hiss and the ability to play FLAC files. And obviously it has Android system, so if multimedia is important to you then the F series is no brainer.
Other than that, the X has a thicker, slightly more organic sound to my ears, but smaller soundstage. I find it sounds nicer with vocals, especially jazz.
F is more flat but sounds awesome with string instruments.
To me, the sound signature difference is more than actual sound quality improvements.
Both hisses with BA IEMs. It doesn't hiss with my dynamic IEMs (EX1000, EX600, IE80.)
Still having trouble with battery life, keeps dying before my iPod. Wish there was super simplified OS, I don't even use apps anyways. Still need a case though haha.
I think the claimed battery life is really overstated. One needs to run off GPS, Wifi, Blacklight, and minimize the screen up time to get those advertised number. Still, the battery life isn't bad compared to the Z1070. I still love mine.
I hear very little hiss with EX800st, but so little its negligible anyway. Haven't tried with any BA IEMs yet, stopped liking them for awhile =P
My battery life isn't half bad; I play 320kbps/FLAC files with the built in noise cancelling on for like 5-6 hours a day, and battery drops about 25%. Overnight drops about 2% on standby. The advertised battery life is pretty accurate IMO.
Thanks for all the impressions everyone.....convinced me to get out of the woodworks to grab one for myself (either next time I go to Japan or have someone coming back from there, Japan Post doesn't like lithium batteries). Deciding between the blue or the gun metal Sony store exclusive for the 807. Planning to run this bad boy with an amp setup (my first portable amp setup) and was thinking of a LOD to Pico Slim. Should be running these with Shure e5c, se530, se535 and also the Westone 4R. I see from some of the feedback that the headphone out is already nice....but I'm sure a dedicated quality amp will bring out more portential from these IEMs. Let me know what you guys think. Keep the impressions comin!
P.S. Been an android fan for awhile, so the transition should be easy .=)
P.S. BTW, anyone have any suggestions other than the ebay LOD or the L5 from Fiio? Is the ALO LOD that much better built? Any feedback there would be nice as well thanks.
