The BXH3 headset has all of the features of the BXH1 but incorporates a silica gel cap that allows you to remove the ear hook and provides a comfortable and secure in-ear fit, making the headset easier to use while wearing glasses or sunglasses. The original design has passed FCC, and CE standards, as well as voluntary RoHS standards. Currently under application for BQB as well. Minimum order quantities apply.
