My earlier feedback on distorted sound on upper bass fixed with this update, no more distorted sound found on bass and treble. Also app error auto closed seem fixed.

I tried to online register MDR 1R headphone serial number as new Sony member and obtain foc prolong warranty period, So strange I also unable to get serial number at the body and box. Upon request Sony feedback me that no serial number for it, but I can see the option to input serial number for...

Thanks for the info ^ ^  

Quote: Cool ! How if compare the two with headphone, eg Sen momentum or Sony MDR-1R?   

EQ off  " almost " no  distortion - agreed. The distortion range is somewhere upper bass, the deepest low no problem at all. before the update distorted sound on both treble and bass, now only bass for certain songs. Sennehisher launch with new IEM IE 800 claims can go high and low without...

Curious any one been compare Sony F/Z/X series vs Ibasso DX100 SQ?   slightly better or heaven and earth? If the sound quality can justify the high price  DX100 and the short battery life i am ready to made a move. crappy OS doesn't really matter border me but i really hate 5-7 hours DX100...

i believed my version same with Croqui, after updated ~audio error and quite on stock application ~bass is really "lacking" not listen to Flac yet, so no sure abt the seconds freezes matter. updated have better setting interface but i still cannot switch on "surround sound" feature...

The reason to pick Sony for the Megabass sound. F806 extremely lacking in bass, even with sennheiser ie8 huge bass IEM, I got in my hand got two Sony Dap: f806 and S739. S739 I can listen continuesly >5 hours for it super dream quantity and quality of bass and more real vocal sound, especially...

100-130 hours using 1R. Bass getting rolled off and lacking in quantity :sweat:

Updated. Kernal version 2.6.39.4 release@build06#1 More responsive EQ on board, Adding some new feature like "surround sound" but sadly tried many times still unable to turn it on.

After >50hours continue running, the distorted and harsh sibilant treble sound tone down, the sound much smoother now,

The distortion not only on bass but treble, cracked sound. My impression towards F807 not as good. The over digital amping(even though flat EQ) over high treble section really made my hear tiring instead of enjoying, I rather enjoy listening with Sony S739. Though muddy sound compare f807...

Haha, seems turn to negative side feedback. My 1R already 150 hours burn. Sound not bad but also not fantastic. What is getting surprise me is the bass quantity now getting lesser and lesser. I am bass head x.x

i tried to off all E setting and sony DSEE ,exloud, clear treble etc features and use Poweramp app doesn't really help to get nicer real voice sound. it liken cheap car hifi set that produce narrow tone and high crack+hiss voice..  

i got my new F806 for few days, wondering the gadget need any burning to get improvemet or not... i found the "voice" sound abit too seriously amp, the kind of crips and digital hifi kind "si","ci" crack sound, and "Thin" feeling in voice especially for male sound abit irritating. i found my...
