My current favorite tip for everything, from fit, isolation to sound quality is Nostalgia Audio's XWB tips. They are one of the few tips that sit at a sweet spot in their sizing between other companies, where their medium isn't as big as others mediums but not too much smaller where I don't get a good seal. SQ wise, they are incredibly transparent with no coloration and let the iem shine through as intended, just the right thickness on the nozzle, incredible hold (never slips, even on nozzles with no notched grip) and they don't make my ears itchy like some other silicone tips do. Highly recommend these guys.
On the topic of Nostalgia Audio, those who know me know I'm a giant fan of the Tesseract and spent half my CanJam attendance at NYC trying to get fellow WCer's to listen to it
. I recently got a demo of the Camelot and also instantly fell in love with it, and luckily unlike the Tesseract, the Camelot can be a CIEM, so guess which guy has THREE CIEMs currently in the works
.
Nothing but praise for the Camelot really, incredibly transparent and uncolored, absolutely fantastic with neutral sources for just being accurate and great timbre with a nice wide/deep and relatively tall soundstage and great resolution. The bass is fast, tight without being overly in your face or punchy, one of the best DD bass out there, mids are neutrally placed, never recessed or too far forward with a nice airy but cohesive and detailed sound while the treble is decently well extended but not over present or piercing to those who may be sensitive. I'd say the only place this set lags behind some of my others in overall technicality is it's imaging, while still great for it's price range, it's no Indigo or Viking. Highly recommend to anyone who just wants a very neutral, accurate and easy listening set, the UIEM (while large, but not as big as Tesseract) is one of the most comfortable UIEMs I've owned, Nostalgia certainly knows how to make a shell AND eartips now.
