If you get the bottle of foam spray then you can just spray a little on a cloth (microfiber preferably) and then clean the IEM by rubbing it. You don't need to soak the cloth, just enough to dampen it. If you use the powder you can use it just straight out of the can on most things but for what...

BKF stuff is amazing. I first learned of it when I was bartending back in the day (yeah yeah I know lol) and I've used it around my house for as long as I can remember.

For those who may be looking for a nice carrying case for your KZ IEMs...I just got one of these to hold my PR2s with 784 core cable and it is VERY nice. Probably going to order another one for my Castor Bass when it finally arrives. Hopefully the link works...

Oh okay. Sorry...I can't read minds. "The expensive one" could have meant anything. 😂

Just looked...yes it is. The official KZ silver/blue hybrid 784 core cable is really nice and should work on the Hydro. I just got one for my PR2s and it's great. You can find it at the official KZ store, Amazon, Aliexpress and several other places and it's not too expensive.

Isn't it just the same QDC / C-pin connector that CCA / KZ use on most all their IEMs?

Buy a new cable. I know it's an obvious suggestion but yeah...buy a new cable.

Ummm...I said I was looking for something for my PR2s.

Yeah...I was actually looking at that one yesterday. It's definitely one of the many options that is making this decision a bit more difficult. I still think I'm leaning towards the KA11 though. 😁

Yeah...I'm just about ready to pull the trigger on the KA11. Just kinda making absolutely sure of everything before I do so. If that's the way I go ill be sure to check back in and let y'all know how it goes. Thanks for the detailed post.

If only you could find any real info about it other than it's $5. Doesn't seem to be any specs listed online that I have found.

Thanks for the detailed explanation. Seems between the two the KA11 would be a better purchase.

Okay...I just found a Tempotec Sonata HD Pro direct from the Tempotec website for $39.90 and of course the FiiO KA11 is $30 so which would be better for my PR2s? Or would I still be better off getting something in the budget category that has a 4.4 mm balanced output (like the Moondrop Dawn Pro...

Yeah...I've been mainly focusing on DAC amps with CS43131 chips. Haven't really looked at too many with AKM chips...any budget minded ones you can recommend.

Unfortunately well above my current budget.
