Hello all,
on tuesday I found this really really great thread and read it completely, some minutes ago I listened with the brown (1000 Ohm), white (680 Ohm) and grey (330 Ohm) filters.
And, as said before, the brown ones create huge bass, but the mids and especially the highs suffer. Bass is more and deeper, but for me simply too much.
The grey ones are in my opinion too thin, clarity and highs are very good, but the lack of bass isn't that fun. That's what I think make them exhausting and a little unpleasant.
After 5 minutes I knew I am going to use the white ones. Compared to the stock filter, the knowles filter (from mouser, shipping to Germany (for $20) in 3 days!! ) sound better. They create a larger sound stage and perform better in highs. I listened to a song with acoustic guitars, one side stock and one side knowles filter. With the knowles filter there is a little more at about 6-8kHz, it sounds closer and bigger and has more attack. Really great!
I will have to enjoy the white filters for a while to say more.
I am using the SE535 for about a year now, often with my Galaxy S4 (poweramp, usually with the fiio E6) and sometimes with my Nuforce µDac2 via computer (asio+foobar). I also use them for home recording and mixing.I think my ears and my brain are well acclimaized to the SE535 so differences are quickly noticed.
I have made a video getting the stock filter out and the new one in, for everyone who is not shure about the modification. It's easy to do. I simply used a small screwdriver (like those that come together with kits for display or battery replacement for smartphones/ipods) to loosen the old filter, then with a needle pulled it out (didn't break). With tweezers I can now put in and take out the filters, even if they are at their deepest position.
Together with pictures I will upload it maybe on sunday.
Btw: my filters pop in nicely and remain there tight.
Edit:
The Video is online.
