The ER2XR presents a super clean, extremely detailed and highly natural sound for the price. In fact, I’m hard pressed to think of an IEM under 200 bucks that can beat it in terms of skill.

the ER2XR gets my absolute highest recommendation if you have around $150 or so to spend and you prefer a more natural and slightly warmer than neutral presentation.
You’ll either love them or hate them. The fit won’t be for everyone and I think that you will need to have a real appreciation of good sound quality to be willing to get used to the unique fit. Saying that, if you do get used to it, you will be one of the lucky ones.
