I recently purchased a set of Comply TrueGrip Pro foam tips for my Samsung Galaxy Buds+ https://www.complyfoam.com/products/tg-truegrip-pro-for-galaxy-buds/
Sound quality is MUCH better, with massively better stereo imaging and sound isolation.
Sometimes these are available from UK sellers like Amazon. I ordered them direct from the States, and did get stung for customs charges - so keep that in mind.
Thanks for the feedback
