James444, i am thinking of getting UE tips for my HJE900 as well. What type of UE tips are you using? From UE website, there are basically two types: black one for Triplefi and transparent one for Superfi. trying to figure our which one gives better seal. Would really appreciated if you or someone else could give me some advice. Thanks!
Thanks for the suggestion. i bought Sony Hybrid. the medium works perfectly for me, and it's really comfortable. would highly recommend it to anyone who is looking to replace the stock RE-ZERO tips. it is so much easier to get a good seal, and i can wear it for a very long time without any pain. probably not good for my hearing tho. :-)
