A dual cup headband is now available for the SRX3 devices. This allows workers
to hear voice directions generated by a voice–directed or voice–guided workflow
clearly and has an increased capacity, compared to the single cup headband
(HD–1500–113), to reduce user noise exposure by including a cup on each ear.
Using Test Standard ANSI S3.19–1974, the SRX3 Dual Cup headset was
determined to have an NRR of 12 dB.
