Pro IEMs for a Song
Get professional Westone in-ear monitoring quality at an entry-level price with the UM1. UM1s provide you with some of the characteristic benefits of Westone IEMs that many of us at Sweetwater consider the most essential. For instance, they didn't scrimp on the drivers — these include Westone's signature balanced-armature drivers, which deliver stellar sound quality and clarity, without the bulk of traditional earphones. True-Fit technology not only ensures you'll find a comfortable fit for your ears, but you'll also get up to 25dB of noise reduction! Add to that MMCX connectors for the removable cable and a great accessory bundle, and you really can't beat the value of Westone's UM1 in-ear monitors.

Balanced-armature drivers offer comfort and detail
Unlike traditional earphones, which use moving-coil speakers, Westone UM1s feature their innovative balanced-armature drivers. These remarkably compact and incredibly efficient transducers take up far less space than typical drivers and won't lose the slightest bit of sonic detail. Even in Westone's single-driver earphones, the size difference makes a huge impact, allowing the earpieces to sit comfortably in your ears while providing superior isolation.

True-fit universal design for comfort and isolation
Short of their Custom-fit personally molded earpieces, Westone's True-fit technology delivers the best acoustic seal and comfort Sweetwater has found in an in-ear monitor. Drawing on over 50 years of experience crafting earpieces for highly technical and medical applications, no one knows ear ergonomics like Westone. Coupled with their excellent eartips, the UM1's low-profile and lightweight earpieces are so comfortable you'll hardly feel them. And they can easily block out up to 25dB of external sound.

Essential accessory kit included
For starters, the UM1 comes with a removable MMCX Audio Round Cable. This system lets you replace your cable at any time — allowing you to switch to a backup cable mid-gig or upgrade your cable anytime. On the other end, your UM1s come with a Fit Kit of tips including five sizes of both True-Fit foam tips and Star silicone tips. And you can keep everything organized and handy with the included monitor pouch.
