Product Description:
With the Panasonic Deep Bass Wireless Bluetooth Immersive Headphones you'll revel in powerful, heavy bass playback with their exceptional, deep bass response through Panasonic's XBS DEEP (Extra Bass System Deep), developed for full immersion with optimal tuning of the housing structure, a driver equalizing function and an equalizing function. Plus, with built-in augmentation, you can your bass to an even higher level of low frequency satisfaction with the simple touch of a button on the earcup housing. The Panasonic immersive headphones also include Harmonic Tuning EQ to clearly play back heavy bass sound by adjusting harmonic overtones, magnifying bass sounds below 100Hz and conversely suppressing bass above 100Hz that can create muffled, noisy sound. A Free-Edge Driver System enables more air to move in the powerful 40mm Neodymium driver units to pump out satisfying bass level more evenly through their distortion-resistant diaphragms, while a Bass-Blow Port provides optimal positioning of the air outflow port in the cabinet, the diaphragm’s precise piston movement crisply reproduces low-end frequency outlines. With a full charge, the Panasonic high-capacity battery provides up to 30+ hours of playback. A handy Quick Charge feature helps keep the bass flowing for up to 2+ hours. Soft, cushioned headband and earpads fit gently over the ears and for hours and hours of anytime, anywhere bass-loving comfort. Adjusters apply even pressure on the head and around the ears for a firm, personalized fit. To help save power when power is low or when fully depleted, an included, detachable 6. 6 ft. cable lets you connect your headphones to devices and home audio systems. A 1. 6 ft. microUSB charging cord is also included. Available in Black and Sand Beige.
