Anker Bluetooth Earphones, Soundcore Liberty 4 Pro! Soundcore Liberty Everything in the photos is included. The M-size ear tips were used a few times. The others are unused. Currently, I've replaced them with Azla ear tips. These have also been used a few times. The fit has improved with these ear tips. The sound quality has also improved. They work well with iPhones and can be paired quickly. I think the connection is better than AirPods. Also, they support multi-device connection, and connect perfectly with a MacBook and a Let's Note. Anker is amazing. I've also used them for Teams meetings. I checked the recording, and my voice was heard without any issues. I'm selling them to organize my equipment!
