It utilizes an over-eared construction to achieve passive, acoustic noise reduction of 14 dB, making this headset quite suitable for use in noisy environments. The microphone also aids in capacity, as its electret, unidirectional boom mic also features onboard noise-reduction. The LA-454 sports a 3.5mm TRRS connection point compatible with many two-way systems. Giving you a microphone bandwidth of 120 Hz to 6 kHz, as well as a frequency response of 80 Hz to 15 kHz in the headphones, this unit will come in handy in loud scenarios, facilitating both hands-free communication and audio quality.
