Audio quality, superior. I must admit that I am quite a fan of the brand for its surprising quality in the hearing section. However, this is the 3rd package I receive from the company, following certain inconveniences possibly in the hearing aid software. The battery is decent, but it is not the best (it lasts a long time if you turn off the LDAC codec and the audio quality is still spectacular). The Edifier application is a jewel and the headphones are as is the description. I would like to leave more opinions, but I still use them and see if there are imperfect ones like in the packages received previously, anyway; The shipment was fast and properly sealed. I love this product!
