Choosing replacement ear tips for an IEM is less about picking the most feature-packed description and more about matching the stated fit and earphone model. In the iem cables & ear tips category, the key choice is between a six-pair Medium option for Astell&Kern AK ZERO1 and AK ZERO2 and a four-pair option identified for KZ ZS10 Pro X.
Quick verdict
The 6-Pair Slow Memory Foam Tips for AK ZERO1 & 2 is the stronger all-around choice if you want the larger listed pack and a Universal compatibility designation. At USD 12.55, it is USD 3.27 below the 4-Pair Memory Foam Tips for KZ ZS10 Pro X, making the price gap straightforward to weigh.
Choose the 4-Pair Memory Foam Tips when your setup is specifically the KZ ZS10 Pro X and the blue finish or 5mm-6.5mm wording suits your matching process. Both use memory foam, so the meaningful difference is the stated compatibility and format rather than the basic tip material.

Product notes
6-Pair Slow Memory Foam Tips for AK ZERO1 & 2
The 6-Pair Slow Memory Foam Tips for AK ZERO1 & 2 is the clearest match for Astell&Kern AK ZERO1 or AK ZERO2 earphones, since both models are named directly and the compatibility designation is Universal. Its slow-expanding memory foam is described as molding to the ear canal, with sound isolation, enhanced bass, and all-day comfort among the intended benefits. The listed version is Medium and Light Gray, with a 4.5mm inner diameter, 12.5mm exterior width, and 11mm exterior height. Those measurements give the choice a defined fit profile. The limitation is that Medium and those dimensions describe the available format, so shoppers seeking a different size profile should weigh that specification carefully before choosing. At USD 12.55, it also has the lower listed price.
4-Pair Memory Foam Tips for KZ ZS10 Pro X
The 4-Pair Memory Foam Tips for KZ ZS10 Pro X makes the most sense for a KZ ZS10 Pro X setup: KZ, the specific model, and the product line are all named in its compatibility attributes. Its blue color and 5mm-6.5mm wording provide two concrete identifiers for matching the replacement to an existing setup. The soft memory foam is described as helping with seal, comfort, and bass response, while the tips are removable and easy to clean. That combination gives listeners a clear reason to choose it when the KZ model match matters. The main limitation is its stated KZ ZS10 Pro X compatibility pairing, so that model reference should lead the decision. Its listed pack is four pairs at USD 15.82.
Final choice by use case
- For Astell&Kern AK ZERO1 or AK ZERO2: Choose the 6-Pair Slow Memory Foam Tips for AK ZERO1 & 2 because those models are explicitly named.
- For KZ ZS10 Pro X: Choose the 4-Pair Memory Foam Tips for KZ ZS10 Pro X for its direct KZ model-line match.
- For a Medium-format specification: Choose the 6-Pair option, which lists Medium plus 4.5mm inner diameter, 12.5mm exterior width, and 11mm exterior height.
- For the blue 5mm-6.5mm format: Choose the 4-Pair option, provided its KZ ZS10 Pro X compatibility matches your earphones.
