Both earbuds charge without issue, but the right earbud doesn't work. The right earbud sometimes connects via Bluetooth, but no sound is heard. The left earbud connects and plays audio without any problems. The instruction manual is included. The charging cable is not the original, but a new, commercially available cable will be provided. The ear pads are also not the original, but will be included. The charger is the genuine product. I'm hesitant to send it in for repair, and I'm listing it for those who have lost their left earbud, or for those who will send it in for repair. Since it's outside the manufacturer's warranty period, the warranty card is not included. The following is an excerpt: Equipped with DSEE HX(*2) in a completely wireless format, which complements the high frequencies of compressed audio sources such as CDs and MP3s, allowing you to enjoy high-resolution sound quality. Significantly improved connection stability thanks to the adoption of a new Bluetooth chip and optimized antenna structure. Reduced video delay. Touch sensor operation on the main unit, and the ability to use only the L or R side. "Quick Attention Mode" allows you to instantly hear the surrounding sounds without removing the headphones, and hands-free calls and single-ear use are also possible. All noise collected by two sensors (microphones) placed on the outside and inside of the headphones, and the player's music signal are digitized. The DNC (Digital Noise Canceling) engine integrates the feedforward and feedback methods to generate reverse-phase sound that cancels out noise with high precision. Enables clearer music playback in a quieter environment. Other features: Noise canceling
