After testing soooooo many my recommendation would the ear soft fx. they are comfy and give good sound reduction. If by basic ones you mean the EAR classic with a flat end then I found those the worse. I started with those many years ago as they were the most well known -go-to - get them everywhere but struggled with fit for various reasons I then went on a long quest to find something better, after many years trying different ones I had another go with them and realised they were not very good, for me anyway.
To get a good sound reduction obviously you need to have a good fit and that is the problem with those classic ones.I have tried making my own outer ear ones with silicone putty (ebay )and were great while it was setting but moved around very slightly in the ear while riding (signing mostly or yawning on the straights ), maybe not soft /rubbery enough.My lid is a good fit and very tight getting it on and some plugs get dislodged at that stage, I have narrow ear canals and one bent ear canal and also get a build up of wax time to time so I do not like plugs all the way down. From an ebay seller I got a tester pack of 5 different ones, there are loads of different shapes and sizes.Always been too tight to pay for the proper made to measure ones.
