Summary: The Westone 4R does exactly the same as the original 4 model, but has a few extra tricks up its sleeves. The user replaceable cable is definitely interesting for all performers and audiophiles. Besides that the inclusion of a hard carrying case is definitely a nice addition. The price difference between the new 4Rs and non-Rs is around $50 which is fair considering what the 4Rs bring to the table.
Pros: Excellent performance across the board, Exchangeable cable, Small for a quad driver in-ear, Good fit, Very detailed sound, Great sound stage performance, Superb bundle, Memory wire (preference)
Cons: Price ($50 more expensive than the Westone 4s), Memory wire (preference)
Summary: Westone have struck gold with the Westone 4 design. It corrects the main deficits of the Westone 3s' design both sonically and durability wise. The price of $449 is a bit on the high side for many. For the avid music listener the sound quality of the Westone 4s makes them good value since you would have to venture on into custom in-ears in order to get anything better at the moment, and those things have zero resale value.
Pros: Sound stage, Tight bass with good extension, Treble extension and detail, Excellent bundle, Comfortable to wear, Sound great with a multitude of tips, Excellent cable, Very neutral presentation (preference)
Cons: Expensive, Not the most musical in-ears out there (preference)
