Enjoy rich and vibrant sound that is delivered from a surprisingly diminutive and light package with the Sony ECM-HW1 channel strip wireless consumer microphone. The ECM supplies you with condenser microphone technology that is capacitor based and offers a robust transient response to sharp sounds and has extra sensitivity to higher frequencies. This lends your recordings a level of fidelity that can be hard to find and is brought to you using Bluetooth communications. The ECM may be small, but it is solidly constructed from ABS plastic, so it will keep capturing audio for you for a long time to come. With an operating range of up to 30 meters and only requiring three AAA batteries for long lasting usage, you'll be able to cover a wide area with more efficiency than ever.
