Seller notes

NEW !! JUST LISTEDChallenge Pro X. Same generation as the Challenge 2X but with a lower cost overseas Microprocessor. Not a mini speaker as in the last generation but a true microprocessor. The cord now uses the same HD Blue cord as the higher priced Challenger2X. Smaller diameter processor so it’s easier on the ear canal. Replaceable foams for years of use. Louder than the original Pro series and just a few decibels lower than the higher priced Challenge2X. This is a real bargain for the week...
