I'd be interested to know how those tips turn out. I was also thinking of changing tips recently. The stock grey triflanges (modded to biflange) lose their suppleness over time and don't keep a seal quite as well I'm finding.
Has anyone cut the stock ety foams for a deeper fit?
Edit: Just tried the stock ety foams and they're too wide to fit into my ear canal past the second bend. :/
