I purchased these as souvenirs during a trip abroad, but never had the chance to give them away, so they've been stored at home. They are in good condition, having only been opened to check the functionality. Please consider purchasing them. 【Description】 ・They feel comfortable to use. ・The sound quality was immersive, with a clear reproduction of even the deep bass. ・They have many features, and in my personal impression, the sound ranges from deep bass to high frequencies. ・These are not Apple AirPods Pro. If you are looking for a perfect product, I recommend going to the Apple Store. 【Packaging】 ・Due to previous complaints about the box, the item will be shipped without the box to avoid unnecessary issues. ・If you don't mind minor dents or damage to the box, and you won't complain about it, I can ship it with the box (no extra charge). ・The item will be wrapped in bubble wrap before shipping. ・A power cable is included. ・Shipping will be via Yu-Packet Post within 1-2 days. 【Function List】 When you put them in your ears, they will appear for new Bluetooth connection.
