The latest Comply foam ear-tip versions are compatible with the Pixel Buds A

Hearing Components is a company that makes the Comply-brand replacement ear-tips that, as it claims, provide an enhanced fit and comfort level compared to the first-party counterparts typically packaged with TWS earbuds from various different OEMs. 

The Comply products set themselves apart in that they are made of memory foam that mold themselves into the wearer's ear in response to body heat. Therefore, their maker asserts that they will stay in place regardless of whatever a TWS enthusiast wants to do with their peripherals in.

The latest generation of these Comply Foam accessories are the TrueGrip Pro 2.0s, which are now available in variants compatible with Google's new Pixel Buds A (and, thus, the higher-end Pixel Buds by default). Hearing Components claims that they also fit into the accessories' charging cases, so that they need not be removed every time they need to power up.

They also come with TechDefender, a feature that apparently helps repel dust and debris from the earbud in question and also discourage "wax build-up". The new COMPLY TrueGrip Pro Tips 2.0s for Pixel Buds-series earphones are available in a 3x pack from complyfoam.com for US$24.99.
