Excerpt: Logitech have being offering great multimedia gear for many years now, but most recently we have seen the Ultimate Ears range of audio products. If you recall we took a look at some of the more modestly priced earphones from this range some time ago with good results. Inside we have a pair of 40mm high sensitivity drivers that we would certainly expect to be of a really good quality.
