4 Balanced Armatures, Comfortable Fit

Aiming for the sound of a custom in-ear monitor with the convenience of a universal fit, the Ultimate Ears UE900s is well suited for personal listening and professional applications alike. The IEM features a small shell that rests comfortably in most ears, regardless of size or shape, thanks to the proprietary fit tip system. With nine different tip sizes to choose from, you can simply lift up the tip sticks and find the best fit. The tips sit on the tip sticks in a unique angle to create an excellent seal. This IEM has four proprietary balanced armature drivers: two for bass, one for midrange, and one for treble. The quad design delivers rich, clear audio, while the three-way crossover and dual bore sound channels keep the highs, mids, and lows phase aligned. Finally, the removable MMCX cable is equipped with an inline mic and iOS controls.

Got mine yesterday, yay my custom tips from my old Super 5s fit! Great packaging and generous supply of tips/extras. Definitely lives up to their original pricing from that standpoint. Here's my quick first impression: Sound Q... is OK. I'll need to put a some hours on them and compare them to few of the IEMs & cans I have, give a go with a few tips, sources, and see if the other cable matters. Keep in mind I'm not intending on listening to anything beyond 320 MP3s on an iPhone 7+ with them so YMMV if you use better source material, amps, etc. I'll probably give them a go on my PC setup (onboard>optical>HK 6xx avr) just to see if a decent amp makes a difference, I recall the Supers responded well to some amping giving a small, but noticeable, improvement. I just don't plan on using them like that on a daily which is where I'm keeping more of my focus. Right off the bat though I'm pretty darn sure these are NOT like my Supers which had a pretty flat, analytic, sound that I compared to AKG K701 at the time (~10yrs ago jeez!). They seem a little bright, not painfully, just a bit more emphasis on the upper range; sound stage is something I don't typically think about but in this case I noticed it feels like it's all right on top of me - it's a bit claustrophobic if that makes any sense. Like I don't need Mark Foster in my lap man, get back on stage. I'm not a big believer in break-in but hopefully these do a bit. Just to give you an idea of where I'm coming from Grado SR-325i, Westone ADV1s, Koss Porta-Pros, and Apple buds are the most common I use. The Grados have my ideal sound signature but I did like my old Supers for the occasional analytic session. I'll do my best to swing back with more thoughts once I've given them a fair shake.
