Unfortunately, we are unable to offer a 'small' memory foam ear tip for the Melomania 1. It is sadly not possible for us to physically manufacture a foam tip any smaller in size than the 'medium' size foam ear tips that already exist (and which come packaged with the Melomania 1).
This is due to the nature of the materials being used as well as the unique size and shape of the tip that is required to fit comfortably on the earbud itself.
The only sizes of memory foam tip that we currently are able offer for the Melomania 1 are medium (which come in the Melomania 1 box when purchased), and large. 10-packs of the large foam tips are available for purchase from Amazon and our CA website https://www.cambridgeaudio.com
