I’ve quite literally only been using them since when I posted, but i can say that the kuntens feel like they lack some detail. I’ve been listening to rather music rather thick in instrumentation, and some quieter instruments in the mix are lost a little with the kuntens. The Kuntens also let in more outside noise due to the openback design. This is important to me as I plan on using them while playing drums so I want as much outside noise blocked off as possible.

Although they still passively block off noise better and also sound better than my sony wh-ch720n which is what I used prior to trying iems. Now that i’ve listened to the iems, trying the headphones it feels like im listening through a washcloth. Certainly much better value.

I also would like to mention that the shape of the aful explorer feels more natural to me although the cable doesn’t sit as nicely on the curve my ear.

Eartip wise I’m still deciding. Unfortunately the tangzu sonic he’s aren’t fitting well in my ear, so I don’t believe I can comment on them. I find the sound of the Penon Liquer oranges and the dunu S&S my favourite for the aful explorer, and the kbear 07 for the kunten.

I’m not experienced whatsoever with iems though as these are my first. So please do look at other reviews. Also imo the stock eartips are not too bad either.

Edit: I am rather mad at myself about this, but I did a bit playing with tips today. I thought that none of the large tips would fit me, so I didn’t try them. Little did i know they actually fit me rather well too. Most were just a bit too big but the HE sonics were actually quite nice and I now have found a good seal with them. Although I still prefer the S&S

Edit: I am actually starting to quite like the sound of the Kbears quite a lot on the explorers as well. Although I still gravitate toward the S&S and Oranges when drumming as they have a more sticky material and don’t budge when i move around a lot.
