Head-worn Microphone for presenters and sports


AKG by Harman Professional recently launched the AKG HC644 MD, successor to the C544 and C555 head-worn microphones. This high-performance head-worn condenser microphone is the perfect tool for presenters in the corporate market but also ideal for sport applications like aerobics with a sweat-resistant design and the ability to fit to all major wireless systems on the market.

The new HC644 MD is well protected against problems which are normally faced by other wireless systems in the low to mid-price range because mostly they are based on on 2,4 GHz technology causing nasty interference with microphones.

The main improvements of the new version are a smaller capsule design with a higher sensitivity, an exceptional RF shielding, a sweat-resistant design and the ability to fit to all major wireless systems on the market.
