I am shocked that there isn’t more buzz about the Tripowin x HBB Kailua. I got mine late Friday, but Greta Van Fleet’s new album came out Friday, and my only listening time on Sat. was that with the Tea2 ( a known transducer for the 1st time ). So this morning I am finally getting some time to listen to the Kailua.
The Kailua mostly does what you think it should base on the graphs. It staked out a middle ground on the treble tuning somewhere between Mele ( or Z300 ) and Olina, and the result is that the bass represents well, but the treble details aren’t lost. I am not sure why, while it has plenty of bass, the slam or impact seemed less than I expected. My guess is that it something to do with Ti coating, but I am don’t know enough about how that impacts the sound. Speaking of the sound, I really enjoyed it, the timber was very natural, it was clean with fast bass, but not tight, and the drivers worked well together. For people who thought Olina was a bit too bright at times, this will be a good choice.
I am impressed at how comfortable these are for me. They are small, much smaller than I expected a 2DD ( 10mm & 6 mm ) to be. The nozzle is small but has a pretty aggressive angle, and they stay in my ears well as a result, but the angle might not work for every ear. I think the angle did force me to go up from a small to medium on the ear tips. I did find that after tip rolling a bit, that I like the sound best with the Final E, or the Dunu S&S, but I am usually a Spinfit CP100+ fan.
The cable will probably be polarizing. It is the thinnest cable I own, but it isn’t bad, just different. Note there is no case with it. I think the cable and case were just trying to put the money into the IEM, not the accessories. If so that works for me.
I really like the Kailua, it is another well made Tripowin IEM, and the HBB tuning we expect. It is probably in my top 3 under $100, which is some ordering of Olina SE, EA500, and the Kailua. I am looking forward to seeing what mods might happen with it too.
…The ‘Hobby’

that thread reads like watching grade schoolers playing “Top Trumps”.
that HFGF would take over as ‘the’ forum for music loving audiophiles to discuss their passion for transducers, hardware or just good ol’ music from Head-Fi and god dang you were right…honest music loving folks are now leaving that sinking ship in droves…
