Additional Information

Customer Review Summary

The Earthworks Audio TC 20 microphone has received mixed feedback during testing. While some users have praised its remarkable sound quality, describing it as a perfect extension of the human ear with impressive naturalness and detail, others have encountered significant issues.

One tester highlighted the microphone’s high-resolution capabilities, noting its ability to capture sound without distortion or colouration, providing a wonderfully neutral tone akin to having an additional ear. Additionally, its robust construction has been commended, suggesting that it is nearly indestructible.

However, there have been recurring concerns regarding quality control. Some users reported that the microphone produced unwanted noises shortly after use, leading to frustration and disappointment. In particular, one individual experienced issues with signal quality and had to return multiple units, indicating a potential problem with consistency in manufacturing.

In summary, while the Earthworks Audio TC 20 has the potential to deliver exceptional sound, potential buyers should be aware of the possibility of encountering quality-related issues.
