I can easily recommend the KB04. It offers a more mature sound signature compared to the majority of IEM in its price range. It is well built, comfortable to wear, and offers a variety of tuning with some ear tips rolling. It does girl-and-a-guitar and your classic jazz trio beautifully, but multi-instrument, high-paced music is where the KB04 truly excels. Take it a step further and feed the KB04 with clean, high-amplitude signal, and you will be pleasantly surprised.
