for KZ ZSN Pro X& Linsoul KZ ZS10 Pro/Pro 2...

I have almost every after-market eartips out there. Once you understand the physics of it, it is pretty clear why Tennmak Whirlwind is the best sounding: a wide-bore eartip sounds like a speaker in a large room whereas a glossy-bore eartip sounds like a speaker in an under-dampened room. Tennmak Whirlwind checks both boxes: 6mm inner diameter makes it one of the widest bore on the market, and it has a glossier bore than other 6mm eartips like TRI Clarion, Whizzer SS20 and BGVP W01, maintaining a good bass and treble impact. It is technically not the glossiest wide-bore eartips ever, as that title goes to Corier Brass, but the Whirlwind is much more ergonomic. Once you are used to the sound of Tennmak Whirlwind, it is hard to go back to a narrower bore eartip. The openness and the soundstage is simply unmatched.Cons:1. Beware of counterfeit. The ones sold on KZ, NiceHCK and other random aliexpress stores are not the same as the Tennmak Whirlwind you get here. The KZ Whirlwind is less rigid, the bore is less glossy, and the overall finishing is poorer. A good rule of thumb is to only get the red/black variant. All other color variants that I have gotten, red/white, black/black, black/white, blue, etc., are the KZ Whirlwind. But even the red/black variant from NiceHCK are the KZ Whirlwind. So yeah, it's tricky...2. Limited sizing. The jump in sizing from S to M is too steep and L is too big for anybody. To help with fitting, try adding o-ring to the end or the front of the IEM nozzle.

I was looking for an excellent set of replacement tips for my IEM collection, and the RHA CL2 planar IEMs specifically.These fit the bill to a T.Well made, comfortable, easy to put on IEMs (tried them on the BGVP DM6/7, TinAudio T2/3, LH Labs Stella, and a few others).And they come in an excellent and highly reusable case. Highly recommended

Bought these to replace the ones that came with my KZ ZS10 Pros (lost one while cleaning). They fit great and the carrying case is a bonus.

There’s nothing not to like about this product! Im honestly satisfied with y purchase!! Thank you again!!

Perfect! Replacement for Ikko OH1 original eartips(vocal). Turns out included case is also perfect for the IEM and spare tips. Case is worth the price alone.

They tone down the sizzling highs a little bit and increase the lower end while allowing the mid range to shine through.

These are fantastic! Comfortable and sound better than most stock tips.

Very good quality. 3 of the sets fit perfectly with my ears.
