I can get Senheiser MX550s or CMX300's. Are they better?
I haven't tried either of these Senns. What I have is the Sony EX-71 and the Creative EP-630. I much prefer the EP-630 over the EX-71 - to me they seem to have better bass (less boomy) and for it is worth, more soundstage. Highs are less shrill too.
Over at Head-Fi, the folks seems to think the CX300 are a great pair of phones. There are supposed to be better than the Creative EP-630, but it will depend on what price you can get them for to decide whether it is worthwhile. In Hong Kong, the EP-630 is nearly half the price of the CX300 - don't think the CX300 is twice as good though.
Also there are alot of new Senn models. There is a PMX70 sports that is supposed to sound somewhat like a PX100. I have a feeling that the PMX70 and the MX70 probably are the same buds with a different design. The MX55 street is also supposed to be very good.
