I got a pair of SE 846s today to use with my stock un-amped AK120. I had been using SE 535s with the brown dampers. I thought the sounded pretty good, but they lacked the bass extension I was looking for. The 120 was running Listrid 2.0 on top of v1.11. I thought that config was helping round out the low end a bit compared the the normal 1.37.
The 846s certainly provide the extended low end as advertised on the box. However, the far upper mids and highs sounded a bit muffled.
I was going to try swapping out the filter, but first I figured I'd try updating the firmware since I remembered the 1.37 having a bit more up top.
Cheese and crackers! I thought my head was going to split in two. The shrillness was what I had feared from what some others had said about the 846s. I put back the 1.11 and then Listrid 2 and then changed out the filter to the white one. Darker firmware, brighter filter was my plan. The nozzle is very well designed, I thought. Made for taking apart.
WOW. The end result was really incredible. I got the nice extended yet punchy low end and the and the upper regions were really just beautiful. For a minute I forgot I was listening through IEMs because it really did sound like a nicely dialed sub. I cant wait to see what they're like after they burn in. Maybe I've just been naively buying the wrong ones, but I didn't know that IEMs could be like this.
I know that the impedance is mismatched according to the 8x rule, but I think I don't care.
I buy a lot of various technological tidbits up to and including eight Leica cameras with a collection of lenses. Of all the "junk" I've accumulated, this is the first time I can think of that an item exceeded my expectations and didn't have some various stuff that bugged me.
