Critic Reviews

The Neumann Killer Has Arrived, and it's from Austria! - Nethervoice

nethervoice.com

Austrian Audio's OC18 microphone is a striking debut that merges tradition with modern craftsmanship. With its C12-inspired CKR12 capsule, it delivers an impressive sound that many find warmer and more balanced than its pricier competitors, like the Neumann TLM 103. However, some users noted slight sibilance issues and a less flattering performance compared to other high-end mics, like the Gefell M930 Ts. At $699, the OC18 offers substantial value for voice-over artists and musicians alike, though its unique design may challenge compatibility with standard shock mounts. Overall, it stands as a formidable contender in the microphone market, promising to win over professional audio enthusiasts.

Austrian Audio OC18 and OC818 Review

musictech.com

Austrian Audio's OC18 delivers an impressive sonic performance with its bright, clear output, making it ideal for vocals and acoustic instruments. Its straightforward design includes useful features like a pad switch and high-pass filter. However, the OC18's tonal differences compared to its sibling, the OC818, may cause confusion for those expecting identical sound profiles. While both mics excel in quality, the OC18's brightness may not suit every application, highlighting the necessity for careful selection based on recording needs. Priced attractively for its caliber, the OC18 is a solid choice for those seeking high-end performance without the premium price tag, but potential buyers should be aware of its unique tonal character.

Austrian Audio OC818 & OC18

soundonsound.com

Austrian Audio’s OC18 condenser microphone delivers impressive sound quality and innovative design, reminiscent of vintage favorites like the C414. Its CKR12 capsule provides consistent performance, making it a stellar choice for studio applications. However, the fixed cardioid pattern limits versatility compared to its sibling, the OC818, which offers multiple polar options. Some might find its unique shape a challenge for compatibility with standard mounts. Despite these drawbacks, the OC18 stands out as a robust and reliable option for serious musicians and engineers, blending classic tones with modern reliability.

Austrian Audio OC18 Cardioid and OC818 Multipattern Condenser Microphones Review — Classical Guitar Tones

classicalguitartones.com

Austrian Audio's OC18 and OC818 microphones are modern champions in sound capture, offering a smooth, detailed audio experience that rivals classic models. The handmade ceramic capsule delivers a consistent performance, while the sleek design and practical features like dual outputs enhance usability. However, some may find the lettering on the OC818 slightly hard to read under certain lighting, and the shock-mount could use a design upgrade. Ultimately, these mics provide a rich and nuanced recording experience, making them a favorite for classical guitarists. If you're after versatility without compromising on quality, the OC818 stands out, though the OC18 offers a more straightforward but equally impressive option for those who don't need extra polar patterns.

In the official live performance video for "Loneliness" by Birdy on YouTube, the microphone used is not the Austrian Audio OC18. Upon closer examination, it appears to be a JZ Microphones model, possibly the Vintage 12, 47, or 67, as the features and logo match those models more closely.
