Ultimate Ears

Ultimate Ears is one of the most well-known and respected names in the custom in-ear monitor (IEM) market (part of the general class: headphones). While historically custom IEMs were targeted at music and sound industry professionals, manufactures have more recently started marketing their monitors to audiophiles, recognizing that many of their attributes might be valued by this community as well. I recently had the opportunity to take a look at UE's entry level 4 Pro Custom IEM and am excited to pass along some thoughts.
