40mm Dynamic Driver 3.5mm Compact Portable Headphones: The [Old Fashioned] headphones feature a large 40mm dynamic driver. A compact internal structure allows for the realization of a large-diameter unit. By optimizing the diaphragm's damping characteristics and the unit's f0, it pursues deep bass resonance that is difficult to achieve in small, open-type headphones. It combines a classic, relaxed listening experience with high-quality sound performance. Comfortable fit & freely adjustable: While inheriting the retractable headband and flexible joint structure of conventional small headphones, the appearance and housing details have been redesigned. A new damper design has been introduced to improve the feel of the joint and the operation when extending or retracting. 0.78mm 2-pin direct-plug detachable cable design & modular separation structure: Adopting a 0.78mm 2-pin detachable cable design, the recessed socket structure further enhances the durability of the main unit. With its more compact detachable cable design, the [Old Fashioned] can flexibly adapt to various usage scenarios by simply changing the cable. Retro-designed compact headphones with excellent frequency response: The [Old Fashioned] headphones combine a uniquely developed open acoustic structure with a specially designed extra-large dynamic driver to achieve excellent frequency response for open-type compact headphones. Even the 3.5mm single-ended version delivers a frequency response faithful to the DF-HRTF characteristics. 【Package Contents & 12-Month Product Warranty】This product comes with a 12-month warranty from the date of order.
