I see this is on warehouse for $247. I bought mine used at this price! These are great iems, I just bought an Es100 recently turning it up to another level. The Soundstage is great, definitely the highlight after the great slam and attack at every frequency. Edit: Here I previously mentioned my difficulty enjoying classical and jazz. I realize now that I'm listening simply to these iems too loud. I still think piano comes in and out of the forward staging too much, but this is mainly because of the great dynamics on this iem, when someone pounds on the keys, you'll know. So unfortunately, on some recordings I have to turn the volume down so low it sounds like I'm outside the hall waiting to be seated, but somehow I can hear every detail and stroke of bow on a string and every press of a piano key. (end edit) The subbass is amazing, mid bass is less so than the subbass but still present. I'm currently trying to find a nice copper cable because the lower mids could use a little love, but vocals (upper mids) are the main draw with this iem. There is a small peak around 5k which brings out cymbals are some bell tones. This causes me to turn down the volume sometimes These get a huge recommendation from me for hip-hop, rap music, and surely pop as well. If you love hearing the production on hip-hop tracks with lifelike detail and immersive soundstage, you gotta buy these. Jpegmafia sounds incredible on these, and so does any other eclectic or seemingly unfocused production like some nujabes, dilla, and madlib. I recommend symbios eartips. (the mediums are tio fat for me so I'm using smalls). If you love acoustic music i suggest try to find some decent foam tips which will bring out the double bass and low end on orchestral instruments. At $247 these are a steal, I like them more than the MD+ which has annoying and unnatural subbass. P. S. I'm a profesional violinist and my favorite over ears rn are the hd600

I also got symbios, small is definitely the way to go I think. Medium didn't work for me. I love these iems, but they have a strange peak that doesn't work with classic music very well for some reason. Most everything else sounds great. Quite detailed but the Soundstage is the real draw here. Quite deep and wide with a decent amount of bass for a neutral /balanced iem

the last thing I wanted to point out is that the best feature of these IEMS for the price is definitely the soundstage, which is deep and wide. Sounds constantly begin behind my head, and the depth of the soundstage makes me question if sounds are originating in real life rather than in the Iems. These qualities, paired with the natural/realistic tone of the T88k suspend your belief to the point when you take them off you just want to put them back on!
