I´m thinking about to get my first pair of custom IEM, but there are so many options! I want an IEM with good bass (quality and quantity), but also as detailed as possible into $700-800 price range. After reading a lot, finalist are UM Merlin, Dream Earz AUD-7x and recently launched 1964 Ears V8. I can´t listen to them before, so I´d like to know what do you recommend between them and/or if you recommend another options. My favorite headhones/earphones have been Stagediver SD3, RE400 and LCD-2.
