I think you are perfectly fine with your Ts. Not like it would be a night & day improvement in any regard.K's Bell-Ti is way out of my budget as of the moment. This Blur where can I check it out? I supposed it is custom-made and not sure if I would want a high impedance earbuds since I don't use a dedicated DAP after I sold my stuff. Pixel phone + Amazon's USB-C mini amp or ES100 + SoundID App is enough for me right now for portability and convenience. My Turandot with the above setup + Koss KPH7G preset sounds very good - impactful, big bass and wide soundstage with smooth yet natural tonality. Listening right now to Alan Walker and some good BTS music.
You can catch up on Blur here and here. Wong's custom made models range from 16Ω up to 400Ω in either PK or MX shells.
