I purchased Samson SR950 Professional Studio Reference Headphones - Open Box. The non open box product was not available at that time. Bajaao claimed it to be checked as working fine, and I trusted the claim and purchased the headphones. On use, I discovered that there is noticable vibration and distortion from the right side ear piece. It appears even at moderate volumes and when connected to any of the several music systems that I have. There is a definite problem with the headphone. But alas, the open box terms of purchase do not allow me to ask for a replacement.
