Wired earphones featuring a 10mm driver and an Extreme Deep Bass Port for enhanced deep bass. The outer box was opened for photography, but the item is unused and in excellent condition, so you can purchase with confidence. I purchased these at Yodobashi Camera in August of this year, but they have been sitting in a drawer, so I am selling them. Please note that the outer box will be removed and folded for shipping. - Model Name: HA-FX33X-R - Driver Unit: 10.0 mm - Features: Extreme Deep Bass Port - Metal Housing: Yes - Tangle-free protector: Yes Thank you for viewing.
