Ultimate Ears

I have 2 pairs of UE IEMs, both wired. I use pair one with a standard 3.5mm plug for my Android phone and 1 pair with a 2.5 mm "balanced" plug for my Astell Kern audio player. Since Apple removed the 3.5mm plug from their iPhone I've been looking for an IEM I can use without the stupid dongle and still achieve audiophile sound during my commute. I was hesitate to spend the 1849.00 on a pair of the CSX 18+, but love my other UE IEMs so much I figured I'd take a chance, after investing in B&O, Flares Pro, EOZ, and numerous other Bluetooth compatible IEMs. Well, I've got to tell you, I should have never wavered. The investment was well worth it! I put the UE 18+ IEMs in my ears for the first time, and firing up my iPhone was a relation. The sound quality, sound field, and detail are unparalleled. It was like a blanket was removed from the music, plus the isolation from outside noise is excellent. I don't hear my morning and afternoon train rides at all. The bass is deeper, the highs higher, the mid-range punchier, and the overall clarity outstanding. I can also lower the overall volume, since there is little outside interference to compete with the music. I love these things! BTW, I download my music to the iPhone either at 24 bit FLAC files, or AppleLoss, so the quality of the source material is pretty high. If you are wondering whether you should buy these, or not, do not hesitate. You will not regret the decision.

I've wanted a custom fit set for a long time and finally pulled the trigger. They sound so good and feel comfortable all day! Don't hesitate like I did, buy them now! You will be glad you did.

Flat and phenomenal, but they will take some adjustment once you get them. Many people like the idea of a "flat" response, but many times when you hear it, that won't be what's actually desired. That's where these, and other high end audio gear, begin to shine. These UE 18+ CSX earbuds can not only deliver the sparkling highs, but are very "thumpy" and can handle rollers. But if that's what you want, be prepared to use the really awesome app (JayBirds users will be familiar with it) or another EQ. I found that I have have a mild midrange boost which favors certain vocals and electric guitars, along with low and mid-bass boosts to bring the thundering lows from electronica, industrial metal, and various aggressive rap/trap tracks to life while being delicate enough for stuff from Clannad and This Mortal Coil, among others. Spoil yourself. Do it.

The attention to detail and customer service is above reproach. Sound quality and fit is fantastic. Bose and the rest take a back seat to these ear pieces.

Unbelievable auditory depth and breadth! And they look awesome, too!
