Summary: What I hear now through these earphones is very fluid and well balanced, very musical. The bass does not thump away as some might want, but it is solid and rich and well balanced with the rest of the music. There are no weird peaks or harshnesses in the sound, and the soundstage is satisfyingly wide with instruments clearly positioned. The mids are warm enough without being over-egged, and the treble is refined and clear with no harshness.
Pros: Musical and satisfying sound. Replaceable cables. Comfortable fit. Reasonable isolation.
Summary: I have put the W4 through its paces, and after the first round of extensive testing, here are my impressions.
My main reason for getting the W4 is to hopefully replace the SE535 and W3, since I find them too colored or fatiguing/bright without EQ. Ideally, I wanted a pair of IEM's that I can listen to without any EQ. In a way, the W4 gives me that, but not in the way I had hoped.
Pros: Great fit, nice cable, pleasant sonic signature (non-fatiguing)
Cons: upper/mid bass still bloated, sub-bass not enough, not enough air
Summary: I bought these as an upgrade from the W3, which while extremely fun, I soon became disappointed in, due to mid bass bleed into the midrange. This caused vocals to become too chesty and distortion rock guitar notes too rounded instead of hard edged. Enter the W4.
Fit and Isolation: Westone 4 is extremely comfortable. I love their size and weight. They only fill up a small portion of the ear. On the downside the nozzle is very short, making them very tip dependent...
Summary: So when I got the earphones my expactations where really high. These were to be my best and last earphones I'll have but it didn't happen. Overall the sound is warm and smooth . It is balanced and nothing really jumps out at you. The bass is as fast and snappy as I've ever heard , the midrange was sweet and nice and the treble quantity was just perfect.
Summary: *I listened to the Westone 4Rs using iPhone 4S and the latest iPod Classic (6th Generation). The below sums up my listening experience from these sources only.*
The Westone 4Rs fit my ears better than any other earphones. With good tips, like Shure’s Grey Flex or ‘Olive’ tips, they feel snug without causing any discomfort.
