This is really helpful, thank you. I didn’t know that Final supplied alternative tips. The adjustment to the signature that you’ve described sounds perfect for my tastes. I just ordered some of the E-type clear tips (without red axis) and am looking forward to trying them. Impressions to follow.
Please do follow up!
My E4000s that I love are locked up at work until next year on account of Covid. I hate boomy base like you (ie. most bluetooth speakers, IEMs, and consumer headphones that are tuned for pop/R&B/EDM). I can't decide if I want to go cheap for 6 months with E1000s or take the opportunity to upgrade to E5000s or something in the $300 range. If you like the E5000s with the clear tips I might upgrade to the E5000s.
