I just bought the NOCS NS400 the other day. The Apple Store in Regent Street stock the NS20 0 and 400 in both black and white. Cost me £69.99.
I bought the NS200, liked them but decided on the Titanium NS400 instead so I've had a listen to both.
First impressions, the NS400 and NS200 have a really nice punchy sound, very engaging and lively. These fit very much like the Senn CX300s in terms of having to stick them in a bit more than normal earphones. The bass is presented very nicely, punchy yet the mids and trebles are also really nicely presented, overall quite a nice balanced sound. They advertise them as having Kevlar cables but to be honest, they feel like normal cables. The only disappointing thing about these are the cables - I thought they were a tad too thin and cheap. The earpieces are lovely, the titanium is light and durable and looks great. Very subtle labeling which is the other thing I love about them, very low key, not in your face, and typical of the earphones coming out of Sweden.
They definitely punch about the price range and I would say that they're possibly one of the best earphones I've owned. The soundstage is nice and wide, the sound is warm I would say, played well with Hip Hop tracks as well as dance and tracks with guitar and piano instruments.
3 days in, loving them. Looking to grab the headphones NS300 now.
