Hi - I'm new here and would really like some advice please! I've read all the comments about the nc-022 supplied headphones but still have some questions! I have the nw-s706 with the nc-022 headphones and wanted to upgrade the headphones. I tried the super.fi 5 pro ones and although the sound is much better (and louder!) than the nc-022, they're not as comfortable as the nc-022 and I had quite bad earache in my left eardrum after using the super.fi's even at low volume for less than an hour. Although the sound quality was great, I actually prefer the more 'compressed' sound of the nc-022 as opposed to the strange 'wideness' of the super.fi's. I read the comments about the ex-90's only being a 'lateral' move from the nc-022 - can someone please explain if they: 1) fit into the ears the same way as the nc-022 (which I find pretty comfortable) as I keep reading that they let in a lot of outside noise. Is the 'outside noise' the equivalent of using the nc-o22 with noise-cancelling swtiched off - or does the leakage come from the fact they fit differently into the ear than the nc-022? I'd like to know as I don't tend to use the noise-cancelling facility anyway so wouldn't mind if the leakage was the same as NC off. 2) as the ex-90 and nc022 are both 16 ohms impedance, does that mean they're as 'loud' as each other? Someone mentioned the ex-90s had a wider range and reduced the hiss on the unit. I can cope with the hiss but wondered if the actual sound quality is better than the supplied headphones. I do like the nc-022's but wanted a slightly better (clearer?) sound perhaps at lower volumes. I know one reviewer Zizone said they were better, but didn't quite explain the differences in a way I could picture. So, if Zizone is reading, can you tell me a little more please? How much better are the ex-90s in comparison with the nc-022 and if anyone else has been able to compare them directly please tell me. Are the clearer, louder, same fit etc? The photo shows a slightly different housing so I want to know if they fit the same way as the supplied phones. Sorry to go on for so long, but it looks like a really informative site so I hope someone can help. Thanks in advance![
