Ultimate Ears is back with a bang, literally, with the UE 4 Pro in-ear monitors that will cost you a cool four Benjamins. The reason behind the high price point is the extreme level of customization one has to go through before bringing a pair of UE 4 Pros home – you will need to make a trip to a recommended audiologist so that molds of your ear and ear canals can be made. These molds will be shipped to Ultimate Ears for the final production of custom ear monitors which were made to fit exactly within your ear.
