The Kz Starlines and Blue-core Turbine looking things are my go to tips now. out of the box the starlines are a bit stiff but after a while they become nicely pliable, at first I didn't like them but now I find they're the ones I am on the floor with a torch peering under the bed and under various furniture if I drop them.
The blue Turbine Lords are the Widemouth Ez-Fit fast tips, I think these are insane but don't suit all Phones and certainly don't suit every users neewds but They can be found for just under a couple of US Shillings. which is good if you learn to rip them from the nozzle and not under the gills in case you rip the super turbo fins.
example. they open up zs6's with a more spacious airy treble (which is a tough burn in - hang in there)... AND baseus EL-01 - WHich i hated and now after about 2 or 3 hours they've smoothed out to some Velvety Rnb - Reggae phones, THe Blue-Core turbo's opening these otherwise Very closed sounding phones to the point where I can listen to these happily now... and actually really like them, not the most revealing or detailed phone but velvety smooth and Vintage warmth... pretty happy.
I mention the blue turbines on zs6's because some peoiple might think it's counter intuitive to allow more treble through and I would agree, IF you weren't able to EQ the sound down, These wide nozzles on the zs6 with the treble smoothed with EQ makes for some nicely Airy sound shapes, especially nice for those who block the vents off because you like that low end, WIth the vents blocked and the Blue-Core Turbo's strapped on, EQ'd top end you have a very cool experience, at least to my ears.
