Additional Information

Customer Review Summary

The Earthworks Audio SR20LS is a microphone that has garnered mixed reviews. While it has been praised for its clarity and definition, especially in capturing sound without the need for equalisation or compression, there have been significant concerns regarding its performance under certain conditions.

Some users have reported that the microphone struggles to deliver satisfactory bass response, particularly when used for specific applications like recording bass instruments. This has led to suspicions of defects in some units, as the expected performance did not match that of other Earthworks models, such as the SR25.

Temperature sensitivity has also emerged as a critical issue; the microphone reportedly operates poorly in cooler environments, requiring it to warm up to optimal temperatures before it functions effectively. This can lead to frustrating delays, as users have noted the need to wait for it to acclimatise, sometimes up to an hour.

Despite these drawbacks, the customer service experience seems to have improved for some, with reports of responsive support that offered replacements when problems were identified. However, this hasn’t mitigated the disappointment expressed by others who felt they wasted their investment, highlighting the importance of careful consideration before purchasing.

In summary, while the SR20LS has potential for high-quality recordings, prospective buyers should be aware of its limitations and ensure that it meets their specific needs and environmental conditions before committing to a purchase.
