Silicon is best
When I got my iQboost ear buts I could appreciate how well they worked but had trouble with keeping them comfortably in my ears for long periods. Once I got the silicon bud tips it changed everything. I can now wear them for a until the battery expires without issue.
The only thing I could improve on is getting the correct size. If you could select a sample pack across 3 sizes it would make it easier to get the best fit.
Now it’s all fitted correctly it’s great.
