Thanks to all X5 modder for the stunning themes. Suddenly, I want to stare to the X5 screen more and more. 

Forgot to mention, I only use headphone out. Using ATH-WS99 as my main reference currently. There's some slight change to the bass and treble that made me favor the old fw 2.0 sound instead of the new fw 2.2.

I've experienced the same change today. Upgrade from fw2.0 to 2.2. I prefer the fw2.0 sound

Currently using Audio-Technica ATH-WS99, I usually let the rim of my glasses above the earpads when I wear them. This headphone more toward sub bass and real tight bass when amped properly. It is definitely fun though, but still a great all rounder. :)

Quote: Thanks for your offer, Mshenay, but I don't think I'll need it. I'm quite happy with my blu-tack mod. 

I see, thanks for the info. Using blu-tack instead, dynamat is hard to find here. This mod is very wonderful, though the romantic voice take a bit hit, but work well with rock. :D

Hi, long time lurker here. I'm wondering, does this mod remove the yellow donut thing (don't know the name) or put it back inside the cup? 

The isolation is just so-so. Tried using it as portable for the first time, definitely the first and the last it will go out. I've tried it in noisy train environment though, so its expected. Even some dynamic IEM also fail this test.

I'm not sure what caused the slight burnt electric smell at the bass port, but this is maybe one of the cause. I charged my C421 and using them at the same time or toggle the bass boost on, now using battery only, no bass boost, listening to speed trance, the burnt electric smell disappear. A...

Quote: Yup, I guess. I think maybe because I turn on bass boost from my C421 amp and play speed trance.

Anyone tried to smell the bass port after long listening session? I smell like something burning but nothing wrong with the driver or sound. Maybe because I've been burn in for a while too.

Well, even before entering audiophile scene, I was a big time AT fans, because they make such cool products. Seriously, their new offering is nothing like their old sound signature, so much maturity they showed. Before this, AT is the last thing I'll equate bass to. Now, what, you want bass...

Does the bass more controlled than JDSLabs C421 OPA2227 based and does the bass more punchy than O2 without toggling the bass boost on? Still wondering about the bass performance in stock form, since that is one reason I avoid O2. I like to have more punch than O2 provide, and if C5 repair that...

Finally, got my WS99 yesterday, burn in around 15 hours I think currently. I must say, the most noticeable change throughout is the mids. Its so balanced that I have to rethink, why the heck AT put Solid Bass badge here? Not to saying the bass ain't solid, its the best bass I ever heard in my...

In the end, my pride as AT fans helped me to pull the trigger for WS99. It will arrive around next week if no delay. I'll burn it in for at least 100 hours before comparing it with DT770 AE demo unit.
