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!

I totally agree with you. I've bought those headphones hoping to have a better sound but I am not satisfied: imho little bass and lots of mids; lots of treble too but hiss especially at low volume. I like sennheiser mx-300 that came with my old iriver mp3 player (which is nearly 4 years old but sounds waaay better than w800). |

I got bored at work today and did some more testing of the sound quality differences between the R1L and R1BC acoustic drives on my W800 running R1BC F/W. In my mind I have confirmed what I said last night. i.e. when using the untouched R1L drivers there is a substantial decrease in hissing. To prove it to yourself all you have to do is compare the background hiss that is present when you enter the MP3 player (not playing music). And, with the untouched R1L drivers there is definately a substantial loss of quality when playing at full volume. The bass rattles and treble distorts. The R1BC drivers are definately superior at high volume.
What I find interesting is that I'm almost certain that the sound on a phone with full R1L firmware did not play as loud. I believe the RIL drivers added to a phone with R1BC firmware plays just as loud as R1BC drivers - just with added distortion. So, I'm thinking there is something somewhere else in the main OS of the phone that interacts with these drivers and controls max volume. Does this make sense? Has anyone else done there own testing with the original R1L drivers yet? |

Noted. But all settings.xml does is record the volume I last had the player at, my eq settings and the file I last played. And, a couple of other items not worth mentioning. I think the actual amp gain is somewhere deeper in firmware. |

Hi guys, I have a w810i and also have the hiss issue... I figured that the hissing is only noticable when the volume is at it's lowest, but at the higher levels I will most certainly damage my ears  . So I bought the Sennheiser Mx500 headphones that have 2 times the impedance and a volumecontrol. This means I have to set the volume on the phone a lot louder and I do not notice the hiss anymore.
It's not really a solution, but it might help a few people out I guess! |

AKSD - I stand corrected - I thought settings.xml recorded the last volume you had the media player set at. I was wrong because when I copied settings.xml with my volume set at 1 it was still recorded as 10 in settings.xml. So, I wonder what the volume string was set at in the original R1L settings.xml? When I get some more time I'll see which volume setting works best with the r1l drivers. Has anyone already found the optimum setting? |

I think 8 should work fine with the R1L series |

I have tried the R1L you've sent me and I agree with you as regards the results.
Using hpm-70 headphones I don't need to have high volume so R1L can be ok, while using sennheisers, which require higher volume (and hiss less), R1B are better.

hi, I got a (vodafone) branded w810i and I would like to fix this hiss problem too. Is there any way for me to do this? without unbranding it or something, so I can still give it back to the store when I get probs. |
