UE FITS / Ultimate Ears Ultimate Ears Not sold in Japan Ear tips are pre-molded. I am selling these as I have no opportunity to use them. I confirmed playback before listing, and it played without any issues. The sound quality is as good as when I purchased them. I have also confirmed that they work with the UE FITS app. I have not tested all the features, so please refrain from making claims or returns after purchase. These are rare, so don't miss this opportunity. I will consider a price reduction only if you can purchase immediately, make payment, and provide a prompt receipt evaluation, so feel free to comment. Bluetooth 5.0 compliant, supporting SBC, AAC, and aptX codecs. The earphones alone provide up to 8 hours of continuous playback, and up to 20 hours with the charging case. The earphones have a built-in microphone for calls and using Siri or Google Assistant. The body is IPX3 sweat-resistant. logicool
