I've had the nocs 400 which was alright. The only problem I had was that it doesn't fit my ear canal very well. I have narrow canals and even the smallest tips were uncomfortable. I liked the small form factor of buds themselves though.
I'm looking to spend up to $100 for some IEMs that are around the same size as the nocs 400 or smaller and has tips for nanrrow canals. Any suggestions?
