i'm using the JVC Spiral dot which is wide bore. i have very limited experience with IEMs only went for the True-wireless route. Its a lot brighter than my Sony WF1000XM3 and Momentum TWE (unfair comparison i know) but clarity is there and the sound stage is better than the Sony, Momentum is better in every way sounding more natural. i cant seem to enjoy them due to the brightness. coming from a AKG owner thats saying a lot lol.
