Panasonic Retro Wireless ANC Headphones

UPDATE: After just a few short months of use, these have stopped working. Even when fully charged, the headphones will turn on and then immediately turn off, still saying "Battery High". Maybe I just got a glitchy pair, but it's frustrating that I only got a couple solid months out of these. Definitely a waste of money. The seller also never reached out about the original box being tampered with. Pretty disappointing and a waste of money! Do not recommend. These are decent headphones with solid ANC and sound quality, especially for the price. I'd describe listening quality as better than standard airpods. The design is also really cute, and the headphones are comfortable. I didn't expect the ANC to completely silence everything around me (and they don't, because they're $50 headphones), but they do a really great job! On medium volume with ANC, I couldn't make out what the person next to me was saying. They do a decent job of noise cancelling even with ANC off. Battery life is great, bass feature works well, and the headphones have minimal sound leakage. The reason I'm giving these 3 stars is because the way the headphones arrived was pretty sus. The seal on the box had been cut, which seems very odd for a new product, and the charging cord is missing. It only came with the AUX cable. I'm not sure if these are rip-offs or if they were previously owned, but it's super lame that I bought them new and didn't receive everything I paid for, and that the box was cut open. I'm hoping that the seller will reach out to me to provide some information or support.
