Yes, agree with your finding.... J +J3ZU, indeed provide very pleasant sound signature.... at least with my MDR-Z1R + Sony Kimbler cable. Those who has these hardware combination, strongly recommended to try with this J +J3ZU....

Possible as you say, but from technical point of view, the earbud actually itself has its own amplifier (with the sound processor), hence firmware likely can control the amount of increment within its amplification stage.

I hope this message to reach Sony, for the improvement in next firmware update : I find the volume sound control +/- steps is not sufficiently gradual enough, the sound level increment or decrement is a bit too much , either a bit too high or a bit too low in sound level, very often we need...

Can you actually, accurately, perfectly re-construct back to the 3.01 sound signature using the EQ (after updated to 3.02), ? it will be really great if you can share the snap shot picture of the EQ setting with us that would perform as 3.01 . In fact I always think Sony is quite...

Wow, I really like your this EQ sound setting ...... it matches well for my 1Z which pair with Z1R and the Sony Kimbler cable. This is now my most preferred sound setting . Thank your very much for sharing this setting.

Standard. As a matter of fact, FW 3.01 really bring out the necessary amount of base, and I equally like the Direct too. I haven’t try other choices of Vinyl selection, likely is not my prefer. Right amount of quality and quantity of base is key to make the sound musically pleasant.

Finally, I found my most preferred sound singanture for my 1Z together with the Z1R headphone+Sony Kimbler cable ... it is Vinyl of FW 3.01 . It is musical, right amount of warm, right amount of clear bass, non fatique treble, overall clear natural relaxing sound. I strongly suggest those who...

Yes, u have exactly same opinion as me that Sony should provides an easy, flexible way of selections of past and new sound signatures. You may refer to my past few posts , advocates for such features ..... not sure Sony will be so nice to us coming out another new FW with such selection features.

Yes, I have the same finding as you ....in fact I don’t feel FW1.2 lack any details , in my case I use Sony’s flagship headphone Z1R, with the upgraded Sony Kimble Cable which actually delivering full quantity of treble with fine details, very well match with FW1.2. For those who use Sony’s...

I just repeat what I had previously said .... Sony just needs to create multiple sound signatures for selection ... .. in this way not only will not upset those original owner who likes and get use to the original sounds , newly added sounds will also give new excitement to those like the new...

It is a matter of relativity ...if you think your head phone is neutral, then you will say 1.2 is quite musical with nice bass in quantity, and 2.0 is analytical , with treble in quantity and reduced in bass quantity ...

Me too .. try many times between 1.2 and 2 as well as attempted various manual setting in version 2, finally still go back to 1.2 , and this is for 1Z + Z1R + Sony Kimbler cable.

My opinion — if hardware can be further enhanced, great .... but more importantly , If FW Is rigid to one one sound signature , and hope many types of head phone can pair well and delighted by many individual taste ... NOT POSSIBLE. If Sony want to sell well and capture bigger market ...their...

1Z is already at the top end in hardware, Sony should continue delight us with FW that is capable to provide variety of sound signatures for selection with including previous original legendary sound signatures but also add-on with new sound signature .... such that it has wider capability to...

Hi Whitigir, can you do a favor .... with your 1Z, in the sound setting, in the Direct Souce Off , turn off all the sound setting ... DSEE HX, DC PHASE LINEARLIZER ...and save the setting, after that then go back to Direct Source on .... then follow by power off and then power on , testing...
