1. Is it normal, that turning EQ with default Custom (all values 0) changes sound output? I mean - shouldn't the output be the same with or without EQ if EQ is set as baseline? 2. Max sound level on Android device seems to be way lower than on PC (both BT connected). 3. Only 2 lowpass filters...

You are right! I've tested all seals and with only 1 set the sound turn from bad/awful to wonderful and just right for me :-) Never had in-ear headphones and didn't realise, that seals makes most of the sound properties. THANK YOU for good recommendation and a professional advice.   Quote:

No, same device/same track, just switching between earphones. Trident just sound distant and flat. Vocal music would be nice, but pop/rock/techno music sounds without energy. Quote:

I have just recieved Trident DN-12 and boy oh boy, what a disappointment - they sound no where near PortaPro and compared to samsungs S3 original headphones fixes only annoying sound at high frequencies (but still too much highs for my taste). Compared even to stock samsung headphones, Trident...

List is amazing :-)   I just have simple question - I like the sound of Koss PortaPro, but I would like to purchase in-ear analogy. Could You recommend some similarly sounding earphones for a reasonable price? I've read lots of reviews, but cannot choose the right ones, because none of them...
