Hello, thanks for the clarification, have just tried the files of the first post, it first that I have the firmware R1BD001 "beta" in W800, and the
VHF_hca file -60_play.apf not has it, but has 2 files that in the file package are not and it are the following:
VHF_2500_play.apf
VHF_2501_play.apf.
After making several proofs with the same files of music going up and by going down the volume my conclusion is that is to hear with but quality the files that have I, is single my appraisal appreciation, maybe my musical ear is not good therefore you puts this --link-- in order that taste those who I have with this firmware to see that appears you.
Best regards

Excellent work...those drivers are totally re-coded are they orignal R1BD? I'm just uploading them...lets see what improvements they have undergone.
@g-roxx....I saw that thanks mate.....I uploaded the W550 driovers..killed all sound on my phone....I then altered them to suit the W800 but the music is only playing in the stereo widening off mode which is something mono output....have to figure out which bit enables the stereo output and enable it....so it will be permanently enabled

Well, I can add this. You can't just copy all the W550 files as you end up with very bad sound. You also can't copy all the w900 files as you'll end up with no sound at all.

tiggerbcn...your files are good...hiss is still present but I'm not sure its any less than R1BC but I feel its a bit less......mongoose could you check them too...bass is exactly like R1BC and hiss is considerably less.

I tried tigerbcn's files and really couldn't tell the difference. So back to original files for me.
Through all this testing there are two things that I have found constant. 1) The hiss that is present as soon as you turn on the Walkman player; and 2) Static/crackle that is present in some songs - especially at lower volumes. The changes in sound quality in some of the earlier modified drivers was very noticeable. The later ones are getting harder to tell from the original drivers. This is making it harder to pick the differences. The SE techs must have experienced the same thing and settled on a compromise.
Anyway, I thought I'd try another avenue of testing: I grabbed the headphones from my son's IPOD and plugged them into my W800 and turned on the walkman. Guess what? The hissing is barely noticeable. Then, I Played a song and the static/crackle is also very hard to pick on the Ipod headphones. I took the test one step further and plugged my HPM70 headphones into my computer. Without anything playing I could hear hissing and squeaks (probably noise from the P.C. bus) and so on. I Played the same MP3's I have been testing and I could hear the same type of static and so on. At low volumes the hiss/hum from the computer is so bad you wouldn't be able to listen. I repeated the test on my PC with the Ipod headphones and found no where near as much hiss or static compared to the HPM70's. I would think the headphones may actually be a major contributing factor to the problem. i.e. they are just too sensitive. The phone is still a contributing factor though as there is not any noticeable hiss when my hpm70's are plugged into the ipod. The static/crackles may be nothing more than just noise in the MP3's - just a thought. Try this test yourself. I'd be interested to hear what other people find.

If you use this file to reduce noise with the mp3 player, will the sound when you talk to people get lower?

I just tested a full set of untouched R1L acoustic drivers (thanks to aksd for providing them). As soon as I turned on the MP player it was immediately obvious that there was less hissing. And at low volumes the hissing was very hard to detect. However, at higher volumes the sound was definitely more prone to distortion. Also, if I’m not mistaken - hissing became more noticeable at high volumes on R1L drivers. So, I would say if you want less hissing at low volume go with the full set of R1L drivers. If you want more volume stick with the R1BC drivers - that's what I’m going to. I also still stand by my previous post that the HPM70's are so sensitive that they contribute/exaggerate the problem.
Off to bed for me now as I want to get a couple of hours sleep before the Socceroos play Croatia in the World Cup at 5:00am. Go the Socceroos!
