I have been using the W40's for about 5 months now. Love them, have no complaints and think they are one of the greatest values in audio at their pricepoint. I came into some money recently and couldn't resist checking out the SE846.
SE846's arrived today! Have played around with all the filters and tips and have settled on the factory installed blue filters with the Westone Star tips. The filter concept is nothing new for Shure. For those of you that remember the E4, it was basically the same concept. Nice touch in the event you bust a tip where you don’t trash the whole housing.
I have only had about 30 minutes or so with them so these thoughts are strictly preliminary. Source is an Ipod Classic (little to no difference amped or unamped). Yes, they sound excellent but no I am not blown away. I think this has more to do with how great the W40 are than anything inherently wrong with the SE846. Yes, it is basically a SE535 with an improved enveloping fullness of sound. From memory there does not seem to be any other changes to treble, midrange, soundstage or general tonality. Its surely still the Shure house sound. For me this is a very tough pill to swallow for $1000 when I find the W40’s just about as good or 90-95% as good. A quick rundown on comparing the two:
Overall, the W40 is smoother without a doubt where the SE846 is slightly brighter making it slightly more fatiguing at higher volumes.
Treble: W40 has more shimmer and extends a little bit more yet is STILL smoother. Pretty amazing actually.
Midrange: Both are excellent. It is definitely a preference thing. The SE846 is MORE forward which I do NOT like, but the W40 has the lower midrange veil which is a drawback as well. I will call it a draw.
Bass: Slight edge to SE846. I have played several key excerpts of music which are really hard hitting multi layered drums and percussion and the SE846 and W40 sound very similar with a little more dynamics on the Shure. Nothing close to a night and day difference. More of a slight improvement, slight edge to the SE846. I would love to measure both to confirm what my ears are hearing.
Soundstage: W40 is somewhat intimate and on the smallish side. SE846 is slightly larger but not BIG by any means.
The Shures are not known for extended treble. Instead, their house sound incorporates an upper midrange spike that gives a “brightness” to the presentation with sort of an illusion of extended treble. At high volumes it can come across a little harsh or fatiguing. Westone takes a different approach of extending the treble but softening the lower midrange to give an overall warmth and lushness which offsets any fatigue from the extended treble.
Given the pricetag if I had to make a choice right now…..I would send the SE846 back and keep the W40. But I need to spend a lot more time with them and more comparisons to the W40. This should NOT be read as a negative review on the SE846. They are great sounding IEM’s. But If you want to take anything away from this preliminary review, it should be that the W40 is one hell of an IEM in the $400 range. Or maybe I just prefer the Westone sound sig? And no, the SE846 is NOT at the level of the JH16. JH16 was more detailed and holographic sounding.
I will surely post more comments after much more listening.
