If you listen to music or watch a video the sound was very good until one earbud got very quiet. If you send a voice message the quality is very bad. The battery was at the beginning comparable wir the Apple AirPods but got worse with every charge.
The sound is okay if you listen music or watch videos but if you have a call or send a voicemail on whatsapp the quality of the sound is really bad. Its not worth the price.
