I picked up the 535 red special edition about a week ago now and it's probably the best iem I've heard to date. Which includes the w4r. I'm not putting down the w4r I just like the 535 reds better. The bass is great. Tight and fast and very accurate. The mids are great like the se535 ,, which I have had two pairs of. The highs are more sparkly then the se535 . They ain't as soft that's for sure. And there is more detail and better seperation.
I don't know I'm loving these things. I'm not to sure it's really worth the extra 500 bucks or so to go to the 846. Or the w60 when they come out or if they are already out. All these companies have priced me right out of their TOTL stuff. I don't know. After having and hearing these I really don't think it's worth it. Just my opinion though
great phone .. Very happy listener.
