Well, that's kinda unfair. All the Shures basically sound the same where all the Westone's sound different. There is no such thing as a Westone "house sound." For example the W3 is distant where the UMPro30 is very upfront and intimate. The UM2 could be considered muddy but the W2 is as clear as an ER4P with more bass. And from a technical standpoint I'd say the Pro30 walks all over the SE535.
