Good seal, feel great. Like them very much
As the title says, it's super comfy. Not too tight or loose in the ear. Easy to clean. No issues to report. Used for Moondrop Blessings 2.
Used these on Moondrop S8 and Noble Falcon Pro (TWS) which have 6mm nozzles. Better seal than 145's. However, I switched to the JVC spiral dot fx10's which can go deeper in the ear with their smaller size. The Spinfits are more reasonable priced.
