#665 Ultimate Ears UE4 Pro Discontinued eBay
Pros: Its tonal tilt of -0.27 sits close to the target, so the overall balance is neither dark nor bright. It uses 2 x balanced armature with an easy 17.5 ohm load.
Cons: Discontinued, so it is mainly found used. A Harman score of 60 places it in the lower part of the in-ear rankings.
