Here's a nearly new pair of Skullcandy Crusher ANC headphones, a gift that I've used a few times. 【Product Description】 The Crusher ANC boasts the most powerful sensory bass in Crusher history. The latest sensory bass reproduces frequencies from 10Hz to 200Hz, expanding the range. Damping has also been dramatically improved, creating powerful, distortion-free vibrations even at high volumes. The stepless slider on the earcups has significantly improved precision, allowing you to adjust the vibrations to your liking depending on the content. Active Noise Cancellation: Newly adopted digital hybrid ANC. It can cancel noise over a wider range, providing overwhelming silence even on trains and airplanes, which further enhances the sensory bass vibrations. Touching the side of the earcups allows you to instantly let in ambient sounds. Your Own Personal Soundstage with the Dedicated App: Everyone hears differently due to the shape of their ears and the range of audible frequencies. The Crusher ANC's dedicated app allows you to create an optimal sound profile tailored to each user through a hearing test. Personal sound will lead you to a new dimension of listening experience with tones you've never heard before. The Crusher ANC can run for 4 hours with a 10-minute charge. It supports rapid charging technology. The Bluetooth codec newly supports aptX HD, allowing for high-quality transmission of up to 48kHz/24bit when connected to compatible devices. This item is a gift and has only been used a few times since purchase, so it's in very good condition, as you can see in the images. However, it is a used item, having been opened and used a few times. I have confirmed that it works without any problems, but please understand that it is a used item. It is not new. Please purchase only if you understand the description. m(__)m
